Getting issue while trying to integrate temporal sdk with my existing project working on .NET Framework. I tried multiple versions but I am getting issue while running a worker,
Also, temporal server is running properly. Getting this issue while worker is getting created - System.ArgumentException: ‘Unable to get assembly manifest ID for build ID’

here is complete stack trace

It seems Assembly.GetEntryAssembly() is returning null in your application, can you confirm? To workaround you may have to set TemporalWorkerOptions.BuildId to a value yourself when starting a worker. It should be a unique identifier for the “build” of the worker (e.g. a version or commit hash), though it can be basically anything.
