…em.Net.Http ref - Build each target framework sequentially in daily CI to avoid OOM kills, matching the approach used in pipelines/ci-build.yml - Revert agent pool back to windows-latest (sequential builds fit in memory) - Build and test the test project explicitly by path - Remove unnecessary System.Net.Http 4.3.4 PackageReference (NU1510 warning) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Sequential TFM builds alone are insufficient — even a single TFM compilation exhausts memory on the standard windows-latest agent (95%+ usage, canceled after 30 min). The larger agent provides enough RAM for this SDK. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Use the same compute pool as pipelines/ci-build.yml, which has sufficient memory for compiling this large SDK. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
The daily CI build was failing due to out-of-memory (95%+ memory usage) causing the build to be canceled after ~54 minutes.

The daily CI was running
dotnet build Microsoft.Graph.Beta.sln --no-restorewhich builds all 4 TFMs in parallel, exhausting memory on the standard hosted agent. The official CI pipeline (pipelines/ci-build.yml) already solved this by building each TFM one at a time.Microsoft Reviewers: Open in CodeFlow
