…21570) (#21608) ## Description Mitigates #21570 (Windows hosted runner "lost communication"), tracked in #21600. **Repo lever found:** DCP 0.27 (bumped in #20874 on 2026-10-10) added WSLc support. When no container runtime is configured, DCP probes `wslc.exe` on every AppHost start. The current `windows-latest` images (`windows-2025` and `windows-2025-vs2026`) install the latest WSL MSI. Since WSL 3.0, that MSI puts `C:\Program Files\WSL\wslc.exe` on PATH. So every DCP start on Windows CI now runs `wslc version`, `wslc info` and `wslc network list`, and DCP kills the last one early ("Context expired, stopping process"). actions/runner-images#14938 reports hosted Windows workers freezing during WSL2 provisioning on the same image family. This PR sets `ASPIRE_CONTAINER_RUNTIME=docker` for Windows test jobs in `run-tests.yml` and for the Windows VS Code extension E2E jobs, using a `GITHUB_ENV` step that only runs on Windows. With an explicit runtime, DCP probes only that runtime. Docker is the only runtime these runners use, and DCP already chooses it today. ## Evidence **7-day bounded analysis.** Scope: main `ci.yml` attempt-1 jobs from 57 non-cancelled runs, about 19.4k jobs. 97 jobs carried the annotation "The hosted runner lost communication with the server". - 45 of 57 runs (79%) had at least one lost runner. - All 97 losses were on `windows-latest`. None were on Linux or macOS. - Every loss was in a test step: `Run extension E2E tests` 44, `Run tests (Windows)` 52, `Run nuget dependent tests (Windows)` 1. - Losses were declared 46–58 minutes into the job, 47 at the median. In a sample of 12 lost jobs, the test step had started 1–4 minutes into the job, so the worker stops about 45 minutes before GitHub declares the loss. These shards normally finish in minutes, and the MTP `--timeout 20m` never fires. - Losses happen only in projects that start DCP: | Project (Windows) | Lost / jobs | |---|---| | VS Code E2E (runs `aspire run`) | 44 / 1085 | | Aspire.Hosting.Tests | 16 / 399 | | Hosting.JavaScript | 7 / 57 | | Hosting.DevTunnels, Hosting.DotnetTool, Hosting.Java | 5 / 57 each | | Hosting.Dotnet | 4 / 57 | | Hosting.Azure, Hosting.Keycloak | 3 / 57 each | | Package tests (Windows) | 1 / 896 | | Dashboard, Components, Azure client and other non-DCP projects | 0 / 57 each | - No resource pressure appears in Windows heartbeats: memory about 20% of 16 GB, C: about 80% with about 30 GB free. **DCP invokes wslc on CI.** The uploaded DCP logs (`logs-Hosting.JavaScript-windows-latest`, run 40196754950) contain: ``` Running WSLC command C:\Program Files\WSL\wslc.exe version --format json Running WSLC command C:\Program Files\WSL\wslc.exe info --format json Running WSLC command C:\Program Files\WSL\wslc.exe network list --no-trunc --format json Context expired, stopping process... wslc.exe ``` `actions/runner-images` installs the latest WSL MSI (`Install-WSL2.ps1`), and `microsoft/WSL/msipackage/package.wix.in` installs `wslc.exe` and adds it to PATH. `windows-2022` does not install WSL2. **An explicit runtime stops the other probes.** Local harness with DCP 0.27.2, putting fake `docker`, `podman` and `wslc` on PATH and logging each call: - `dcp info` probes `docker --version` and `podman container ls`. The wslc probe is Windows-only. - `dcp info --container-runtime docker` probes only `docker --version`. Aspire passes `ASPIRE_CONTAINER_RUNTIME` to DCP as `--container-runtime` (`DcpHost`, `DcpDependencyCheck`). **Validation plan:** this PR's Windows DCP logs should show no `wslc.exe` invocations, and the loss rate is compared across this PR's CI runs. Results will be posted below. ## Checklist - Is this feature complete? - [x] Yes. Ready to ship. - [ ] No. Follow-up changes expected. - Are you including unit tests for the changes and scenario tests if relevant? - [ ] Yes - [x] No. This is a workflow-only change.
