Upgrade WCF application to .NET 6.0

We have a WCF application developed with .NET Framework 4.6.1. We have already a modernization project going on to migrate to .NET 6. This modernization project will take a year or more to complete.

Because the supporting for .NET Framework 4.6.1 is ending soon, we need to urgently migrate this WCF application to .NET Framework 4.8 or .NET 6. Half of our apps and services are in both .NET Framework and .NET Core 3.1. We are thinking about migrating all apps and service to .NET, but I read that WCF service is not supported in .NET 6.

  1. Can .NET Upgrade Assistant migrate WCF app to .NET 6?

  2. Is there a migration utility available to migrate WCF to .NET 6?

  3. Is it safe to migrate the WCF app to .NET Framework 4.8 and get support from Microsoft for the next 1-2 years at least?

Hi @WonderfulWorld-6345,
If you want to use .NET 6, I recommend you to use an alternative to WCF: gRPC,CoreWCF,ASP.NET Core MVC.
Or use the WCF Web Services Reference Provider Tool, a Visual Studio Connected Services extension that lets you connect .NET 5+, .NET Core, or ASP.NET Core projects to web services.
https://docs.microsoft.com/en-us/dotnet/core/additional-tools/wcf-web-service-reference-guide

The original implementation of Windows Communication Foundation (WCF) was only supported on Windows. However, there is a client port available from the .NET Foundation. It is entirely open source, cross platform, and supported by Microsoft. The core NuGet packages are listed below:

 System.ServiceModel.Duplex
 System.ServiceModel.Federation
 System.ServiceModel.Http
 System.ServiceModel.NetTcp
 System.ServiceModel.Primitives
 System.ServiceModel.Security

The community maintains the server components that complement the aforementioned client libraries. The GitHub repository can be found at CoreWCF. The server components are not officially supported by Microsoft. For an alternative to WCF, consider gRPC.

You can consider gRPC + Web API combination by following microservice architecture in .net 6 with visual studio 2022.
