Describe the bug

I tried the new minimal API code generated validation. Everytime I call any endpoint, I have this exception.

Here are the versions I use

<PackageVersion Include="Microsoft.AspNetCore.Mvc.Testing" Version="10.0.0-preview.3.25172.1" />
<PackageVersion Include="Microsoft.AspNetCore.OpenApi" Version="10.0.0-preview.3.25172.1" />
<PackageVersion Include="Microsoft.EntityFrameworkCore.SqlServer" Version="10.0.0-preview.3.25171.6" />

The test is done in a dev container, using mcr.microsoft.com/dotnet/sdk:10.0.100-preview.3

Expected Behavior

No exception occurs

Steps To Reproduce

• add builder.Services.AddValidation(); in startup
• add <InterceptorsNamespaces>$(InterceptorsNamespaces);Microsoft.AspNetCore.Http.Validation.Generated</InterceptorsNamespaces> in the csproj
• Implement a handler that looks like

    private static async Task<List<TodoItem>> Handle(ApplicationDbContext dbContext)
    {
        return await dbContext.TodoItems.ToListAsync();
    }

• Call the handler

Exceptions (if any)

System.InvalidOperationException: Property 'Microsoft.EntityFrameworkCore.Storage.IDatabaseFacadeDependenciesAccessor.Dependencies' not found on type 'DatabaseFacade'.
