.NET

Describe the problem you are trying to solve.
We want to use Google.OrTools but there are company policies that require third-party code to be authenticode signed.

Describe the solution you'd like
Authenticode sign the assemblies inside Google.Ortools.

Additional context
Protobuf already has authenticode signing support, we can get implementation information from them protocolbuffers/protobuf#5756 and grpc/grpc-dotnet#24.
