GitHubModel enum cannot use implicit using while builder method can

[maddymontaquila]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

When using the GitHubModel enum, it cannot be referenced with an implicit using, even though the AddGitHubModel builder method itself works with an implicit using. This inconsistency forces explicit namespace usage for the enum.

Example (fails without explicit using):

Example (works with explicit using):

Expected Behavior

I expect the GitHubModel enum to be usable with an implicit using, just like the AddGitHubModel builder method, so that explicit namespace imports are not required.

Steps To Reproduce

1. In a project with Aspire and GitHubModel, attempt to use the enum in a file relying on implicit usings.
2. Observe that AddGitHubModel works, but referencing GitHubModel.OpenAI.OpenAIGPT4oMini requires an explicit using.
3. See screenshots for reference.

@davidfowl I also feel like it should be in the same namespace as the extensions or the ns be implicit.

However when you are at var chat = builder.AddGitHubModel("chat", and intellisense tells you it accepts a GitHubModel, as soon as you type it it's automatically added (C#SDK at least) and it's smooth.

Make the package add the implicit using.
