Conversation
Adds a 'Project structure and Dockerfile' sub-section to the web app hosting section covering: - WebApp.Testing must use Sdk="Microsoft.NET.Sdk.Web" or wwwroot content items are excluded from the publish output (symptom: StaticFileMiddleware warning in container logs) - ReferenceOutputAssembly="false" on the production project reference also suppresses content items - launchSettings.json is ignored in containers; default port is 8080 - Razor views are pre-compiled in Release; .cshtml files absent is expected - DataProtection and libgssapi_krb5 warnings are harmless in test containers Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Adds a "Project structure and Dockerfile" sub-section to the web application hosting section of the getting-started guide, covering the common pitfalls when containerising an ASP.NET Core web app that also hosts NServiceBus:
WebApp.Testingmust useSdk="Microsoft.NET.Sdk.Web"— using the plain console app SDK excludeswwwrootcontent items from the publish output. The symptom isThe WebRootPath was not found: /app/wwwrootin the container logs.ReferenceOutputAssembly="false": must not be set on the reference to the production web app project (it also suppresses content items). This attribute is only correct onWebApp.Tests→WebApp.Testing.launchSettings.jsonis ignored in containers; ASP.NET Core defaults to port 8080 on .NET 8+..cshtmlfiles in the publish output is expected.libgssapi_krb5.so.2are harmless in test containers.Test plan
