This is an msbuild target that will try to create the key file that is used by the project it is installed to when it doesn't exist already.
Which is a well known problem for open source projects:
You do want to sign your assemblies, but you don't want to give away the key file.
See the version list below for details.

dotnet add package CreateSnkFile --version 1.0.1
<PackageReference Include="CreateSnkFile" Version="1.0.1" />
paket add CreateSnkFile --version 1.0.1
