Introduction

Web services have revolutionized the way applications and platforms communicate and exchange data. With their ability to transcend platform and application boundaries, web services provide numerous advantages that have made them an integral part of modern technology.

Advantages of Web Services

Web services enable communication between any third-party application by using the Simple Object Access Protocol (SOAP) over HTTP.
In addition to including the endpoints for the send request, they offer a uniform set of rules for communication. For Web services like WCF, we don’t require a lot of configuration.

Web Services can be used as web page requests and help us to receive data.
They support faster communication.
They support the highest priority of interoperability.
By using Web services, applications can easily communicate and exchange data among themselves.

Disadvantages of Web Services

While web services offer numerous advantages, they are not without their drawbacks. It’s important to consider these limitations when evaluating the suitability of web services for specific applications

The request for Web services is larger than that encoded with the binary protocol. It does matter when there are low-speed connections or busy connections.
Web Services do not have any other way to discover the service.
It uses XML, which needs to be processed in order to be read. It supports many standards, that should be followed while creating an application.

By considering these limitations alongside the benefits, developers and businesses can make informed decisions about when and how to leverage web services effectively, striking a balance between functionality, performance, and compatibility.

A subset of XML called Web Services Description Language (WSDL) is used to transmit XML communications. The behaviour of a web service is described using the WSDL. An XML-based interface supports it.

E.g.

The above example is a sample of the WSDL.

The address element contains the endpoint of the client.

We can view the WSDL directly on the browser window, as mentioned below.

http://domain.com/webservices?wsdl

How to add a web service using WSDL?

For Adding Web Service in the project, we have to use the following steps.

1) Right-click the project in which you want to add the service and click on “add” option.

2) Next, select "Service Reference" from the following dialogue box.

3) A new dialog boxwill open after clicking on the “add service reference: option.

In the above example, the address will contain a WSDL path. It may be from the local system or any online URL. After clicking on the “ok”, Button, the service gets added to the project.

For security, we can use an SSL certificate at both the ends. It is an asynchronous request and response while calling the SAP endpoints. The SAP gateway port should always be open while sending the request and receiving the response.

We can call endpoints using the following sample code.

If we are using an old version of the dot net framework, we have to use the following code for sending requests to SAP gateway:

Tips to Choose the Right Software Development Company for Your Business in the UK

As a business owner in the UK, you know that having the right software solutions can give you a competitive edge in the marketplace. Finding the right custom software development company can be a daunting task, but with the global nature of the technology industry, you’re not limited to companies located only in the UK.

Here are some tips to help you choose the right custom software development company for your UK-based business.

1. Look for a Company with Relevant Experience and Expertise

When looking for a custom software development company for your UK business, it’s essential to find one that has experience working with businesses similar to yours. The company should have a track record of delivering high-quality software solutions and have expertise in the specific technology stack you need.

Here are some questions you can ask to help you evaluate a company’s experience and expertise:

Can you provide examples of the types of businesses you have collaborated with in the past?
What technology stacks are you proficient in?
Can you show me examples of software solutions you have developed for businesses similar to mine?

2. Communication is Key

When working with a software development company, especially one that is based outside the UK, communication is critical. It’s essential to find a company that communicates clearly and regularly throughout the development process.

Here are some questions you can ask to evaluate a company’s communication:

How often will you provide updates on the progress of the project?
Who will be my primary point of contact during the development process?

3. Look for Custom Solutions

It’s essential to find a software development company that offers custom software development solutions tailored to your specific needs. Avoid companies that offer one-size-fits-all solutions, as they may not be able to meet your unique requirements. A bespoke software development company can help you create software solutions that are tailored to your specific needs and can give you a competitive edge.

Here are some questions you can ask to evaluate a company’s ability to provide custom solutions:

What is your process for understanding my business requirements?
How do you ensure that the software solution you develop meets my unique needs?

How do you ensure quality when outsourcing software development?
Can you provide examples of successful outsourced software development projects?
What is your process for managing outsourced software development projects?

5. Post-development Support and Maintenance

Software development is not a one-time project. After your software is developed, you’ll need ongoing support and maintenance to ensure it continues to function properly. Outsource your work to a software development company that offers post-development support and maintenance services. Make sure the company you choose has a clear support and maintenance policy and offers a range of support options.

Here are some questions you can ask to evaluate a company’s post-development support and maintenance capabilities:

Choosing the Right Software Development Company for Your Business in the US – What to Consider?

meta_prasad — Mon, 08 May 2023 10:05:26 +0000

As technology continues to shape the way businesses operate, software development has become a critical aspect of any business. However, not all companies have the resources or expertise to develop custom software in-house.

This is where software outsourcing comes in. Hiring a bespoke software development company for your US-based business can help you obtain high-quality software solutions that meet your unique needs.

However, with so many software development companies available in the US and abroad, choosing the right one can be overwhelming. Here are some key factors to consider when selecting a custom software development company for your US-based business:

1. Experience and Expertise

When outsourcing software development, it is crucial to choose a company with a proven track record of delivering quality software solutions. Location does not matter; look for a company with experience in developing software in your industry. They should also have a team of skilled developers who are well-versed in the latest technologies and programming languages.

2. Effective Communication and Collaboration

Any successful outsourcing partnership heavily relies on effective communication as a key factor to ensure that the project is completed on time, within budget, and to the satisfaction of the client. The software development company you choose should be able to communicate clearly and regularly about the progress of your project. This is important especially if you are outsourcing to a company outside of the US. They should also be willing to work closely with your in-house team to ensure that the final product meets your expectations.

3. Cost and Budget

Outsourcing software development outside the US can be a cost-effective solution for businesses. However, it is essential to have a clear understanding of the costs involved and establish a realistic budget for the project. Be sure to ask for detailed quotes from multiple software development companies and compare them based on the scope of work and the quality of the solution provided.

4. Flexibility and Scalability

As your business grows and evolves, your software needs may change. Therefore, it is important to choose a custom software development company inside or outside the US that can provide flexible and scalable solutions. They should be able to adapt to changes in your business requirements and offer solutions that can accommodate future growth.

5. Security and Confidentiality

When outsourcing software development, you are entrusting a third-party company with sensitive information about your business. Therefore, it is essential to choose a custom software development company that takes security and confidentiality seriously. Look for a company with robust security protocols and procedures in place to protect your data.

6. Customer Support

Software development is a complex process that may involve unforeseen challenges and issues. Therefore, it is crucial to choose a company that provides excellent customer support. They should be responsive to your queries and concerns and offer timely solutions to any issues that may arise. If your outsourcing partner is located outside the US, ensure they are able to bridge the time-zone gaps to meet your requirements in a timely manner.

Converting an MVC web APP to .Net Core Web App

meta_prasad — Mon, 13 Apr 2020 07:56:19 +0000

History

Like many others, we have been working on MVC 5 based web applications since 2013. With Microsoft planning significant investment into the open-source development platform .Net core, we saw the advantage of migrating our current applications to the new platform sooner rather than later.
The first version of .Net Core 1.0 was released by Microsoft in 2014, followed by several versions, most recently .Net 3.1.1 in January 2020. At the time that we started the migration in 2019, we found .Net 2.2 to be a stable version with a well-developed community advanced enough to answer our queries. The web application that we decided to convert to .Net Core was developed in 2017 on the .Net 4.5.1 MVC platform.

Initial considerations
Evaluating the conversion risk is an essential first step before convincing the client to invest in the new technology. Several factors need to be considered, including the project timeline, the scale of the project and the available resources. Using a team that has worked with the technology for at least a year or two is the best option for reducing risk in such a conversion project. A great option is using interns as an additional resource, as the project provides them with the excitement of learning something new.

HOW to start?
The first step is to check the old application with the tool called NET Portability Analyzer Tool. This tool analyzes assemblies and provides a detailed report on the .Net APIs that are missing for the applications or libraries to be portable on .Net Core. It is not a tool which will automatically convert the .NET MVC app to a .NET Core, but it is a useful initial guide towards identifying the portable and non-portable items.
The tool details are available on the Microsoft website:
https://docs.microsoft.com/en-us/dotnet/standard/analyzers/portability-analyzer
The tool can be downloaded using the link: https://marketplace.visualstudio.com/items?itemName=ConnieYau.NETPortabilityAnalyzer

The screenshots below show some of the tool outputs:
Portability Summary

Details

Missing Assemblies

Creating the new project
It is not useful to open the entire MVC project as a .Net Core project immediately in Visual Studio (VS) 2017, as it will result in a huge list of errors that are difficult to address one by one. A better approach is to create an empty project and copy a few models, controllers, views or corresponding files at a time into the newly created .Net Core project in the VS 2017 environment. After each addition, build the project, analyze and fix the errors.
What were my next steps? Let me give you some technical bullets here.
One of the important steps is to move the connection strings settings from Web.Config to JSON settings in the file named as AppSettings.JSON .
It is necessary to add a middle layer file for the session and call it in the StartUp.cs file. so that all the session objects set on the Global. asax file that do not exist on the .Net Core project will go into the middle layer file and register as a service in StartUp.cs. The Session dependency is included by adding AddSession into ConfigureServices of StartUp.cs
Convert all of your class libraries created separately to .Net standard Class Libraries wherever required by creating a .NET Standard Project and add the references wherever required for the new .NET Core Web App project you have created.
All static files like Images, icons, CSS, JS, email templates need to be copied into WWWRoot. The file locations have to be changed across the project wherever they are referenced.
The Route.config file should be replaced by adding the MapRoute in the StartUp.cs file.
We can create Set and Get extension functions Like SetObject and GetObject for handling session operations as shown below

We have two parts in our project Web App and Web API so we have to add the DI (Dependency Injection) for calling WebAPIClient and HostingEnvironment (IWebAPIClient webapiclient, IHostingEnvironment env)

What can be done on SSL redirection?
We have to add following setting in AppSettings.json file

Also we have to add following code in Startup.cs

Third party Dlls
Every project has some third party Dlls used in the project for a specific purpose. For our application, the third party Dlls like EPPlus, ICSharpCode.SharpZipLib library worked on the .NET Core project without any issues. However, it is possible that certain third party tool kits are not compatible with .NET Core. Some can be downloaded from NuGet or by contacting a third party vendor.
There may be instances where third party assemblies used in the project do not work and cannot be bought from third party vendors. In this case, I would recommend finding a solution that omits the tool altogether. It pays to think of this early whilst updating any web app that might be migrated in the future. This way incompatible third party Dlls can be avoided in favor of compatible tools, in order to save work at the migration stage. One such example is Nreco PDF to Image renderer, which has a version that is compatible with .Net Core available from a third party vendor.

The technical points in this article refer to architectural changes, I will cover the common conversion issues and deployment in the next article so stay tuned…
