I want to generate a proxy class for the external wcf service of SAP. All goes well but the generated code can't be build in VS2022 in a 8.0 project and also not in standaard 2.1 framework.

Has anybody had the same problem with packages that point to 6.0.*

I want to generate a proxy class for the external wcf service of SAP. All goes well but the generated code can't be build in VS2022 in a 8.0 project and also not in standaard 2.1 framework.

Has anybody had the same problem with packages that point to 6.0.*

• wcf
• -8.0
• svcutil.exe
• dotnet-svcutil

• You may use donet-svcutil with traget framework 8.0 and you can post specific errors in the code to find a solution. Finally, update your VS 2022. – Jiayao Commented Feb 3 at 4:16

I'd normally say you should explain what you did, and post the code as text, not images. That image shows you already found that svcutil has problems with .NET 8 and tried to use the preview 2.2.0-preview1.23462.5 that was supposed to fix it - but didn't.

Right now there's a newer version in NuGet, 8.0.0-preview1.24619.5, released 20 days ago. You should upgrade dotnet svcutil to the latest pre-release and try again with :

dotnet tool update dotnet-svcutil -g --prerelease

There's no guarantee this will fix all issues as this is still a preview. It should remove references to obsolete packages at least

The solution was to add the correct missing namespaces
