Best Practices for Performance Optimization in .NET Applications

meta_prasad — Mon, 30 Oct 2023 08:14:04 +0000

At MetaSys, we had the opportunity to transition a legacy application, initially constructed with the .NET Framework 1.0, to the more modern .NET Core. We put into practice some of the relevant strategies detailed in this blog post. In a landscape where both the application and the business are in a state of evolution, the focus is to get the new features into production. However, during this rewrite, we paid special attention to performance optimization across the modules that were upgraded. Subpar performance can exasperate users, potentially driving them away and exerting a negative impact on customer retention and overall business success. Performance optimization will remain an ongoing effort, however, rewriting the application in .NET Core presented a significant boost.

In today's digital era, users have come to expect websites and online applications to load quickly and function seamlessly. For businesses utilizing .NET Core in their web development, emphasizing performance optimization is essential to delivering a flawless user experience. This blog aims to be a guide to best practices, exploring critical aspects such as start-up time, database access, query efficiency, and caching for ASP.NET web applications.

Improving ASP.NET Web Application Start-up Time

The start-up time of your ASP.NET web application significantly impacts user acquisition and engagement. You can enhance this aspect by implementing the following methods:

Utilize the .NET Core Runtime: In our experience, leveraging the improved performance of the latest .NET Core runtime version significantly reduced application start-up time.
Implement Dependency Injection: Incorporating dependency injection simplifies the management of object dependencies, offers better control over application initialization, and results in quicker start-up times.

Optimizing Database Access and Query Performance in ASP.NET Applications

Efficient database access and query execution are crucial for enhancing the overall application's response time. Implement the following techniques to optimize these areas:

Employ Asynchronous Database Calls: Use asynchronous database calls to release the main thread, increasing program responsiveness and improving performance.
Optimize Database Queries: Enhance database performance by optimizing queries, utilizing appropriate query patterns, and generating suitable indexes to lessen the burden on the database server.

Leveraging Caching to Enhance ASP.NET Web Application Performance

Caching is a powerful tool for boosting ASP.NET web application performance by reducing unnecessary calculations and database requests. Employ the following caching techniques:

Output Caching: Cache the rendered output of web pages to serve subsequent requests faster and alleviate server load, resulting in a more efficient user experience.
Data Caching: Implement data caching to reduce database hits and enhance response times for frequently accessed data, contributing to a more responsive application.

Minimize the number of HTTP requests and reduce the size of resources in ASP.NET web applications

To speed up application load times, it is essential to minimize HTTP requests and optimize resource size:

Bundling and Minification The number of HTTP requests and the total amount of resources can be decreased by bundling and minifying numerous CSS and JavaScript files.
CDN Integration Use a CDN to offer static materials from geographically dispersed servers, lowering latency and speeding up loading times.

Optimize the performance of data binding and data controls in ASP.NET web applications

The speed and general performance can be affected by data binding and controls:

Use Server-Side Data Binding Judiciously Often, Server-Side Data Binding outperforms Client-Side Data Binding, particularly for large datasets. Depending on the specific application being developed server-side data binding can degrade performance. Hence this aspect needs to be thought through.
Reduce the Use of Unwanted Controls Make sure that controls are only applied when necessary and avoid the use of unrequired controls.

Recommended techniques for optimizing session state management in ASP.NET web applications

For the maintenance of user-specific data and preferences, effective session state management is necessary:

Consider Session State Modes Based on the needs and scalability requirements of your application, select the appropriate session state mode (InProc, StateServer, or SQL Server).
Place Cookies Don't store excessive quantities of data in cookies because doing so increases the size of HTTP requests and responses. Best practices for optimizing the performance of client-side scripting in ASP.NET web applications The user experience and application performance can be significantly impacted by client- side scripting:
Reduce DOM Manipulation DOM manipulations can be resource-intensive, so try to do them less frequently. Cache items instead, and whenever you can, update in bulk.
Async and Defer Use the "async" and "defer" properties to load scripts in order to prevent rendering-blocking and speed up page loading.

Optimize the performance of AJAX calls and asynchronous operations in ASP.NET

While asynchronous actions are necessary for responsiveness, they also need to be optimized:

Batch AJAX calls To cut down on round trips and overhead, combine several AJAX calls into a single batch request.
Implement Cancellation Implementing cancellation will improve user control and the user experience by giving users the ability to stop lengthy asynchronous activities.

Leverage browser caching and HTTP compression to improve the performance of ASP.NET web applications

For repeat visitors, load times can be greatly lowered by utilizing HTTP compression and browser caching:

Set the Right Cache Headers Set the right cache headers to allow the user's browser to cache static resources.
Enable HTTP Compression Minimize the size of the data transfer between the server and the client by enabling HTTP compression.

Delivering a superior user experience requires optimizing the speed of your ASP.NET web application. You can speed up response times, boost user satisfaction, and enhance business results by implementing these best practices and strategies.

Overview of Swagger

meta_prasad — Tue, 28 Feb 2023 12:47:05 +0000

Testing web APIs is indeed a challenging task, especially when compared to testing traditional user interfaces. The absence of a graphical interface makes it difficult to test the functionality and reliability of an API, which can lead to potential issues and a poor user experience. This is where Swagger comes to the rescue.

Swagger is a game-changer in the world of web API testing. It simplifies the testing process by providing a user-friendly interface for testing web API endpoints. With Swagger, developers no longer have to rely on third-party tools such as Fiddler or Postman to test their APIs. Instead, Swagger provides an all-in-one solution that allows developers to easily test and validate their APIs, ensuring that they are working as expected.

What is Swagger?

Swagger is an open-source framework that helps developers to design, build, and document RESTful APIs. It provides a simple and interactive way to describe the structure of an API, allowing developers to visualize and test the API’s endpoints.
It provides a UI representation of the Restful API without any implementation logic.
Swagger generates UI using the Swagger specification file (swagger.json), which is generated by Swagger tool based on service code.

This file describes the capabilities of the service.
It also specifies the methods supported by the service.
Moreover, it provides information about method parameters.

Swagger also generates documentation for the API that can be accessed by other developers, stakeholders, and end-users, making it easier for everyone to understand how the API works.

How Swagger Works?

When you open a webpage that uses a RESTful API, the browser will first request the webpage from the web server. This request will trigger a separate request to the API server, which will provide the necessary data for the webpage.

Swagger UI is automatically generated from the API server’s OpenAPI specification, which is a standard for describing RESTful APIs. This UI can be viewed within a browser and provides a comprehensive and interactive documentation of the API’s endpoints, parameters, request and response examples, and other related information.

Benefits of SwaggerUI:

SwaggerUI has several advantages over other frameworks, making it a popular choice for Web API development. Some of the key benefits of SwaggerUI include:

User-friendly interface: The visually appealing and intuitive interface allows for easy collaboration and input from various team members during the design process.
Improved Documentation: The comprehensive documentation feature not only facilitates internal communication within the team, but also supports the automation of dependent processes.
Convenient Testing and Debugging: The user-friendly interface and testing capabilities of SwaggerUI make it a valuable tool for quickly resolving any Web API issues that may arise during development.
Ease of Use:

SwaggerUI is useful for testing and debugging Web API problems.

How to Install SwaggerUI?

To install SwaggerUI in an Asp.net core Web API project, use the following command in the Package Manager Console:

Install-Package Swashbuckle.AspNetCore

This will add the necessary dependencies and configure SwaggerUI in your project, allowing you to easily document and test your APIs.

How to configure Swagger in Asp.net Core Web API?

To configure Swagger, we have to add the AddSwaggerGen method into ConfigureServices.

After that, add the Swagger and SwaggerUI into the Configure method. The code will look like below:

When you run the application and navigate to http://localhost:52046/swagger/index.html:

You can see above image has ValuesController with five different endpoints.If you add a new controller, for example, CustomersController, and add methods to work with the customer data, these will automatically begin to appear in the SwaggerUI.

At MetaSys Software, our team of expert developers is ready to help you with any questions you may have regarding Swagger. We specialize in creating custom software solutions using the latest technologies, including DotNet , Azure,FileMaker, PHP, React, and React Native.

What, Why, and How of Microservices?

meta_prasad — Fri, 09 Apr 2021 08:20:04 +0000

What are Microservices?

Historically applications were Monolithic applications where the architecture was a unified and closely coupled integrated unit. Microservices, on the contrary, are smaller independent unified business modules. Each module in Microservices performs its own unique business functionality, at times with dedicated databases.

As shown in the above image, the architecture of Microservices consists of independent smaller units, which are interconnected and managed with the help of API Gateway.

Why opt for Microservices instead of Monolithic Applications?

A Monolithic application is a big container with a collection of different smaller independent parts combined and coupled tightly together, which creates varied inseparable disadvantages.

Here are a few disadvantages of Monolithic services.

• Inflexible – Monolithic applications cannot be built using different technologies.
• Unreliable – One bug or issue in the application may result in the shutdown of the entire system.
• Not Scalable – The tightly coupled nature of a Monolithic application does not scale easily, as workloads cannot be easily distributed across multiple nodes or hardware.
• Hinders continuous deployment – Continuous delivery and deployment in short cycles of time is difficult due to the monolithic nature of the application
• Longer development timelines – The development of Monolithic applications requires lengthy timelines since every feature demands rebuilding of the entire application.
• Complex applications –Incorporating changes in complex monolithic applications become expensive and a maintenance nightmare.

As mentioned earlier, a microservices application is a collection of small independent services designed for different business purposes. In Microservices, each individual service is self-contained. Communication with each self-contained unit is managed by an API Gateway. There are various API Gateways available, and the client can communicate with different business functions of Microservices via the API Gateway.

Features of Microservices

• Decoupled Components – Decoupled services in Microservices architecture enables the entire application to be built, modified, and scaled up quickly with ease.
• Componentization –As each service is an independent component, they can be easily individually replaced and upgraded.

• Undivided business capability –Each Microservice is effortless and focuses on a single business capability

• Autonomy – Developers and teams can work with minimal dependencies, thus increasing development speed and turnaround time.
• Continuous delivery – Allows frequent releases of features by systematic automation of application creation, testing, and approval.
• Responsibility – Microservices treat applications as products and not projects, ensuring the responsibility is in-built.
• Decentralized governance – With no fixed or standardized tool or any technology patterns, developers have the freedom to choose tools based on the requirements to accomplish the job within stipulated timelines.
• Agility – New features can be added easily and quickly developed. A Microservices architecture supports agile development.

Advantages of Microservices

• Independent development – all services are independent of their business purposes and usage.
• Independent deployment –The architecture of Microservices allows services to be individually deployed.
• Isolation of fault – the system continues to function even if one service or a part of the application ceases to work.
• Mixed technologies stack – it is not mandatory to use only one of the platforms for development. We can use multiple platforms and built Microservices architecture as per the need of the application.
• Individual scaling – scale different individual components and deploy them individually without affecting other components.

Best Practices to Design Microservices

• Separate data store for each Microservices
• Maintain the level of code maturity
• Separate build for each Microservice
• Deploy services into containers
• Treat server as stateless

Disadvantages of Microservices

• Huge number of services makes application management tough to track
• The developer will require to solve issues pertaining to Network latency and load balancing

How to create Microservices and API Gateway interface?

Note: This is for those who are familiar with ASP.Net project concepts.

In this demo, we’ll cover the following points,

1. Create two Microservices
2. Create an API Gateway
3. For creating the demo project VS2019 or VS Code, .Net Core 3.1 SDK needs to be installed on the machine

Steps to Create a Microservices Demo Project

Step 1
• Create two .Net Core web API template project for different purposes
• First, UserService project for user data purpose
• Second, ProductService project for product data purpose
• Create UserController in UserService project and ProductController in ProductService
• Add simple action into the controller that returns the string for testing purpose
• If required, connect API project with the database

Step 2 – Test the above web API project with the help of postman individually

1.) Product Service Output

2.) User Service Output

Step 3 – Create .net core web empty template project for API Gateway with the desired name. In this instance, we chose ‘APIGateway’

Step 4 – Include the dependency of ocelot API Gateway from NuGet package manager

Step 5 –
• Create a JSON file to configure API Gateway for web API and assign a name. In this instance, it is ‘ocelot.json’
• Include the following code text to the JSON file for configuring the API Gateway. In this demo project, API Gateway is used for routing purpose. API Gateway serves different purposes such as:
o Routing
o Caching
o Logging
o Authentication
o Authorization
o Load balancing
o Service Discovery

Note: In the above image, detail of ocelot.JSON are in the comments

Some details of ocelot.JSON are considered while configuring API Gateway from the ocelot package.

• The request forwarded to URL set byDownstreamPathTemplate, DownstreamHostAndPorts and DownstreamScheme
• Ocelot will use the UpstreamPathTemplate URL to identify where the DownstreamPathTemplate request is to be used.
• Ocelot uses UpstreamHttpMethod to make a difference between multiple requests with the same URLs but with different HTTP verbs. We can set a specific list of HTTP Methods or set a blank to allow any of them.

Step 6 – Configure the JSON file for application configuration as shown below in Program.cs file

Step 7 – Set Ocelot middleware ASP.Net project as shown below in Startup.cs file

Step 8 – Run the application to test the working condition of API Gateway. Before running, make sure all projects are marked as startup projects. To handle request from the API Gateway application UserService and ProductService must be running.

Note: If you are testing project through VS2019, the following steps will help you mark all projects as the startup project.

Step 9 – Right-click on the main solution and click on the property, alter the settings as shown below

Step 10 – Below screen shows the final output. When you run the project, all three startup projects will be running, at times, on different ports. We need to check if Customer and User service received a call from the API Gateway project, as shown below.

Hope this article has helped you understand the know-how of Microservices. If you have any questions, please feel free to drop them in our comments section. Happy to Help!
Happy Coding!
