Unlocking the Power of .NET Core Web API: Connecting to a Remote WCF ASP.NET Framework net.tcp Service

Introduction

In today’s fast-paced digital landscape, building scalable and efficient web applications is crucial. One way to achieve this is by leveraging the power of .NET Core Web API and WCF ASP.NET Framework net.tcp services. In this comprehensive guide, we’ll explore how to connect a .NET Core Web API to a remote WCF ASP.NET Framework net.tcp service, unlocking the full potential of your web applications.

The Need for Integration

With the advent of microservices architecture, modern web applications often consist of multiple services and components. Integrating these disparate components is essential for seamless communication and data exchange. .NET Core Web API and WCF ASP.NET Framework net.tcp services are two powerful technologies that can be integrated to create a robust and scalable web application.

Prerequisites

Before we dive into the implementation, ensure you have the following prerequisites:

• .NET Core 3.1 or later installed on your machine
• Visual Studio 2019 or later (optional)
• A basic understanding of .NET Core Web API and WCF ASP.NET Framework

Step 1: Create a WCF ASP.NET Framework net.tcp Service

First, let’s create a WCF ASP.NET Framework net.tcp service that we’ll later connect to from our .NET Core Web API.

Create a new WCF Service Library project in Visual Studio 2019 or later:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="WCFService1">
        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:8080/WCFService1" />
          </baseAddresses>
        </host>
        <endpoint address="" binding="netTcpBinding" contract="IWCFService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
      </service>
    </services>
  </system.serviceModel>
</configuration>

In this example, we’ve created a WCF service named WCFService1 with a net.tcp endpoint.

Step 2: Create a .NET Core Web API

Next, let’s create a .NET Core Web API that will connect to our WCF ASP.NET Framework net.tcp service.

Create a new .NET Core Web API project in Visual Studio 2019 or later:

dotnet new webapi -n MyWebAPI

In this example, we’ve created a new .NET Core Web API project named MyWebAPI.

Step 3: Add WCF Client Library to .NET Core Web API

To connect to our WCF ASP.NET Framework net.tcp service, we need to add the WCF Client Library to our .NET Core Web API.

In the terminal, run the following command:

dotnet add package System.ServiceModel.NetTcp

This adds the necessary WCF Client Library dependencies to our .NET Core Web API.

Step 4: Create a WCF Client in .NET Core Web API

Now, let’s create a WCF client in our .NET Core Web API that will connect to our WCF ASP.NET Framework net.tcp service.

using System.ServiceModel;

public class WCFClient
{
    public async Task<string> GetData()
    {
        var binding = new NetTcpBinding();
        var endpointAddress = new EndpointAddress("net.tcp://localhost:8080/WCFService1");

        using (var client = new WCFService1Client(binding, endpointAddress))
        {
            return await client.GetDataAsync();
        }
    }
}

In this example, we’ve created a WCF client class named WCFClient that uses the NetTcpBinding and EndpointAddress to connect to our WCF ASP.NET Framework net.tcp service.

Step 5: Consume WCF Service in .NET Core Web API

Finally, let’s consume our WCF service in our .NET Core Web API.

using Microsoft.AspNetCore.Mvc;

[ApiController]
[Route("api/[controller]")]
public class ValuesController : ControllerBase
{
    private readonly WCFClient _wcfClient;

    public ValuesController(WCFClient wcfClient)
    {
        _wcfClient = wcfClient;
    }

    [HttpGet]
    public async Task<IActionResult> GetData()
    {
        var result = await _wcfClient.GetData();
        return Ok(result);
    }
}

In this example, we’ve created an API controller that injects our WCFClient instance and uses it to call the GetData method of our WCF service.

Conclusion

In this comprehensive guide, we’ve successfully connected a .NET Core Web API to a remote WCF ASP.NET Framework net.tcp service. By following these steps, you can unlock the full potential of your web applications and leverage the benefits of both .NET Core Web API and WCF ASP.NET Framework.
