Targeting release/13.5 based on the source PR milestone 13.5.

Why

PR #18981 moved the experimental DotnetProjectResource type from the shared Aspire.Hosting.ApplicationModel namespace to the integration-specific Aspire.Hosting.Dotnet namespace and applied the ASPIREDOTNETPROJECT001 experimental diagnostic, aligning it with the Go, Python, and JavaScript hosting integrations. The PR body's "User-facing usage" section shows C# consumers now need using Aspire.Hosting.Dotnet; to reference the resource type directly (e.g. IResourceBuilder<DotnetProjectResource>).

What changed

• src/frontend/src/content/docs/integrations/frameworks/dotnet/dotnet-host.mdx — added a short code sample, right after the existing experimental caution note, showing the using Aspire.Hosting.Dotnet; import needed to reference DotnetProjectResource directly in C# AppHosts.

Files modified

• src/frontend/src/content/docs/integrations/frameworks/dotnet/dotnet-host.mdx

No new pages were created; this is a targeted addition to the existing Dotnet hosting integration reference page.

Pull request overview

This PR updates the .NET / C# Dotnet hosting integration documentation to reflect that the experimental DotnetProjectResource type moved to the Aspire.Hosting.Dotnet namespace, so C# AppHosts must import that namespace when referencing the resource type directly.

Changes:

• Adds guidance that DotnetProjectResource should be imported from Aspire.Hosting.Dotnet.
• Adds a short C# snippet demonstrating using Aspire.Hosting.Dotnet; when using IResourceBuilder<DotnetProjectResource>.

I checked the C# and TypeScript snippets against the new APIs and namespace move. This looks good.
