Summary

This PR successfully implements the requested feature to include known/registered providers in error messages when a provider is not found.

Key Changes:

  1. Enhanced error messages in both DefaultClientServices.cs and DefaultSiloServices.cs
  2. Error messages now include a sorted, comma-separated list of known providers for the requested kind
  3. Fixed a pre-existing typo in DefaultClientServices.cs where "or" was missing
  4. Fixed using statement ordering to comply with .editorconfig
  5. Added comprehensive tests in ProviderErrorMessageTests.cs

Example Output:

Could not find Clustering provider named 'NonExistentProvider'. This can indicate that either the 'Microsoft.Orleans.Sdk' or the provider's package are not referenced by your application. Known Clustering providers: AzureStorage, Default, DynamoDB.

Fixed using statement ordering to comply with .editorconfig (System.* namespaces first, then alphabetically sorted). See commit cd40fc7.

Look at the build errors

Fixed the build errors in ProviderErrorMessageTests.cs. The issues were:

  1. Using AddConfiguration() on IConfiguration instead of using ConfigureAppConfiguration() on the host builder
  2. Using parameterless UseOrleans()/UseOrleansClient() which aren't available on IHostBuilder
  3. Missing #nullable enable directive for nullable reference types

See commit 221f423.
