I ran into the same issue today. The documentation here: https://docs.microsoft.com/en-us/dotnet/core/additional-tools/dotnet-svcutil-guide?tabs=dotnetsvcutil2x seems to indicate that it should work with later versions.

It doesn't. Here is my output on dotnet core 5:

dotnet svcutil

I was able to work around this by downloading a 2.1.x version of the .NET Core SDK. The exact version I downloaded was 2.1.300 from this page: https://dotnet.microsoft.com/download/dotnet-core/2.1

All of our systems are at 3.1 since it came out. The current release is 5.0. 2.1 capabilities for us are not enough.

@imcarolwang can you please look into this and see if you can repro?

[dsimanis]

I have installed version 2.0.2 and it is finally working.
