A recent Razor refactor removed public APIs that ASP.NET Core's runtime view compiler depends on, forcing an emergency restore.

The Razor declaration/implementation split that flowed into the VMR [1] stripped out two critical public members: RazorCodeDocumentExtensions.GetCSharpDocument() and RazorCSharpDocument.GeneratedCode. ASP.NET Core's Mvc.Razor.RuntimeCompilation.RuntimeViewCompiler relies on these APIs and broke in the product build [2]. Chris Sienkiewicz restored both public members to unblock the product [1]. Separately, Viktor Hofer fixed an official build failure in Roslyn by removing stale SDL validation parameters that Arcade had already dropped from its post-build template [3]. The msbuild updates continue flowing through the VMR codeflow pipeline into dotnet/dotnet [4], with aspnetcore dependency updates from the optimization channel keeping pace [5]. All four commits across these repos landed cleanly overnight.
