DSH Open File Bridge for Visual Studio 2022

This VSIX is a background-loaded AsyncPackage. Each Visual Studio process enumerates its own IVsRunningDocumentTable, listens for RDT changes, and publishes one protocol-v1 snapshot. This avoids the ambiguity and integrity-level failures of attaching externally through EnvDTE/ROT.

Only absolute, existing local files are published. Dirty state is read through IVsPersistDocData; source buffers are never copied.

Build and test

Use a Visual Studio Developer PowerShell or a machine with the VS 2022 extension workload:

dotnet restore CoopWithDsh.sln
dotnet test CoopWithDsh.sln -c Release
dotnet build Prophet.CoopWithDsh\Prophet.CoopWithDsh.csproj -c Release

Install the generated .vsix from the Release output, restart Visual Studio, then type @ in DSH. The snapshot heartbeats every 15 seconds and is removed on normal package/process shutdown.
