Sign your assemblies with a strong name

[rdvanbuuren-gasunie]

What would you like to be added:
Please sign your assemblies with a strong name.
See https://learn.microsoft.com/en-us/dotnet/standard/assembly/sign-strong-name for more info.

Why is this needed:
So our strongly named assemblies can also use your nuget packages. Currently this is not possible and will throw a build error.

This was done with #2044, will be part of the upcoming 8.0 release.
