Release executable fails with "TcDUT cannot be serialized / parameterless constructor"

[FellowWithLaptop]

Hi there,

I tried to use the latest release (v0.7.3) of protoc-gen-twincat.exe on Windows, but it crashes immediately when processing enums or messages.

The Error:
System.InvalidOperationException: TcHaxx.ProtocGenTc.TcPlcObjects.TcDUT cannot be serialized because it does not have a parameterless constructor.

The Solution:
I was able to fix this locally by cloning the repo and running dotnet build -c Release. The locally built executable works perfectly.

Thanks for this great tool!

Hi @FellowWithLaptop,

this should be fixed with the latest release v0.7.4.
Thanks
