Minimal API Validation: Can the source-generator discover the [ValidatableType] across assemblies?

[Trivivium]

Hi, I'm trying out the new source-generated validation for Minimal APIs. It's encouraging to see development in this area! 🚀

The solution I'm working on have a lot of Minimal API endpoints across multiple modules. Each module is a dedicated C# project. This helps keep the API endpoints close to the related code and organised. The modules are referenced by a "host" project configuring shared concerns such as logging and authentication... and now the AddValidation() method call too.

Host-->A[Module A]
Host-->B[Module A]

All API endpoints in the Host project is discovered by without any problems. But the endpoints in either Module A or Module B isn't 😢

Is this a known limitation, or possibly a bug?

A possible workaround:

Repeating the AddValidation() method call in each module and adding the <InterceptorsNamespaces>$(InterceptorsNamespaces);Microsoft.AspNetCore.Http.Validation.Generated</InterceptorsNamespaces> property to the .csproj works.
