VS2022 Service Reference Error MSBuild & SvcutilBootsapper

Question

I'm using VS 2022 (17.3.4) to add a Connected Service WCF Web Servcie to a .net standard 2.0 project. The Service reference configuration progress page shows an error while creating the service reference:

MSBuild version 17.3.1+2badb37d1 for .NET
C:\Users\efi.nuget\packages\system.io.hashing\6.0.0\buildTransitive\netcoreapp2.0\System.IO.Hashing.targets(4,5): error : System.IO.Hashing doesn't support netcoreapp2.0. Consider updating your TargetFramework to netcoreapp3.1 or later. [C:\Users\efi\AppData\Local\Temp\WCFConnectedService\2022_Sep_26_09_48_22\svcutil_bootstrap\SvcutilBootstrapper\SvcutilBootstrapper.csproj]

Build FAILED.

Failed adding service reference(s). Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

How can i fix this issue, or is there a workaround to add an external WCF Web Service Connected reference?

Hi @Jiayao Wu-MSFT ,

Thank you for your response.

Unfortunately the dotnet-svcutil tool will not run in my netstandard2.0 project. See https://github.com/dotnet/wcf/issues/4766

I'm using the Visual Studio 2022 Connected Services to add the new reference. No coding involved in this:

Hi @Eric Fitskie ,

Depending on your situation, try using the dotnet-Svcutil tool to update the service reference for your scenario.

In addition, if possible, please provide some code to reproduce your problem.
