One note - we did not create templates named
DurableFunctionsEnttiyClass-CSharp-1.x
DurableFunctionsEntityFunction-CSharp-1.x

We only created the -2.x variants.
Just want to expressly check that this is not an issue

Hey Andy, which template pkg will these be available in? I want to make sure we don't deploy ahead of these templates being available
