Loading

  • Make new parameters on Router nullable
  • Move check for OnNavigateAsync == null below await previousOnNavigate to ensure that previous on navigates complete even if onNavigateAsync parameter is removed
  • Use ExceptionDispatchInfo.Throw instead of ExceptionDispatchInfo.Capture.Throw for re-throwing errors and preserving context
  • Throw JSException from getLazyAssemblies on-call for invalid inputs
  • Change constructor for LazyAssemblyLoader to take injected IJSRuntime
  • Use Assembly.Load to verify if assemblies have already been loaded during pre-rendering
  • Add tests for catching exceptions thrown for invalid inputs

Does this need to be returned?

Yeah, I don't see how this can work asynchronously without doing so.

We return a promise in L305. This is the same thing we were doing before for this scenario.

Do you mean that we need to return a Promise in the scenarios where we are currently throwing an error?

This is the main change in this commit since we previously returned a dummy Promise.resolve(0) if the parameter was invalid.

Sorry, yes I think you're right @captainsafia. There was something about the diff (the removal of line 348) that made it look as if we were now discarding this promise. I didn't read it clearly enough.
