A new version was released yesterday. The version is not yet supported by .netstandard2.0 and consequently the old .net framework 4.6.2 is no longer supported by Microsoft.
You can use the library with .NET6 but I recommend upgrading to .NET8.
I’m working on a REST Api gateway for CasparCG Server, let me know if you’re interested in this project. I can create a new post on this topic.
Best regards.
