Question re dotnet-svcutil and bootstrapper

I'm trying to run dotnet-svcutil in the debugger and have an issue with the bootstrapper and package restore.

If I build the tool and run it from the command line, e.g.

dotnet-svcutil "http://localhost/WCFTest/Service1.svc?wsdl -d D:\WCFTest -r "C:\Users\passp\source\repos\WCF_Test\SharedDataContracts\bin\Debug\netstandard2.0\SharedDataContracts.dll" -v debug"

This works fine. I get a bootstrapper created at say "...\AppData\Local\Temp\dotnet-svcutil-lib_Temp\2020_Jul_15_14_44_27\SvcutilBootstrapper\bin\Debug\netcoreapp3.1" and this is fully populated with dependent assemblies like NewtonSoft.Json.dll (9.0.0.1).

If I run the same in the VS debugger the console output looks identical, up to 'Invoking bootstrapper...'. But none of the packages get restored in this case so the tool fails with " System.IO.FileNotFoundException: Could not load file or assembly 'Newtonsoft.Json, Version=9.0.0.0...".

Any ideas?

I was hoping to see if there was anything I could do about [https://github.com/dotnet/wcf/issues/3812](https://github.com/dotnet/wcf/issues/3812).
