DSH Open File Bridge for Visual Studio
This VSIX supports Visual Studio 2022 (17.x) and Visual Studio 2026 (18.x). It 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 Visual Studio 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.
