Raise better error messages on mismatching Fabric version

[revoltez]

after adding StreamPrinter.cs and calling it in deploy.cs : await PerperContext.CallAsync("StreamPrinter");
running the project should print:

Hello world from Deploy!
Hello world from StreamPrinter!

but executing dotnet run will result in the following Error:

Using:
Perper version 0.8.0-rc1 (previous versions do not implement ConfigurePerper() extension for HostBuilder)

Make sure the Fabric version you are using matches the version of the agent library. E.g. use perper-fabric:0.8.0-rc1 (:

working now, thanks

Sweet! Going to repurpose the issue to be about error messages, if you don't mind 😁

@bojidar-bg sounds great
