🔍 Build Failure Analysis

Summary — The build failed due to a transient network error while downloading a bundled component during the TestBuild_linux_x64 leg; this is not a code issue in the PR.

Root cause 1: Transient download failure in DownloadBundledComponents (infra flake)

Only one of the 24 build legs (2_1_TestBuild_linux_x64) reported an error; every other leg (AoT_macOS_x64 ×3, TestBuild_linux_x64 leg 2_0, TestBuild_linux_arm64 ×2, TestAsTools_windows_x64 ×2, FullFramework_windows_x64 ×3, AoT_windows_x64 ×3, TestBuild_windows_x64 ×3, TestBuild_macOS_x64 ×3, TestBuild_macOS_arm64 ×3) compiled with zero MSBuild errors. The single failure is an HttpRequestException/HttpIOException ("The response ended prematurely") thrown from Microsoft.DotNet.Arcade.Sdk.DownloadFile.DownloadWithRetriesAsync while the DownloadFile task executed the DownloadBundledComponents target in RestoreLayout.targets. This is a mid-stream TCP/TLS connection drop while downloading a bundled-component artifact over the network — a classic feed/CDN flake, not something caused by any source change in this PR. No other symptom (no CS####, MSB####, NU####, analyzer, or public-API error) was found in this leg or any other.

Affected files / errors

• src/Layout/redist/targets/RestoreLayout.targets:314 — DownloadFile task in target DownloadBundledComponents (project src/Layout/redist/redist.csproj) failed: HttpRequestException: Error while copying content to a stream. → HttpIOException: The response ended prematurely. (ResponseEnded)
• Build-level: redist.csproj and dotnet-sdk.proj both reported as failed as a consequence (247–250s runtime), consistent with a hang/drop partway through download rather than a fast-failing code defect.

Proposed fix

No code change is warranted — the DownloadFile task already retries (DownloadWithRetriesAsync), and this failure occurred after those retries were exhausted against a flaky connection. Recommend simply re-running the failed TestBuild_linux_x64 leg (or the whole pipeline) rather than investigating further; if it recurs consistently on retries, it may indicate a degraded upstream feed/CDN worth flagging to dotnet/arcade/infra, but a single occurrence is best treated as transient.

Build overview

• Leg: 2_1_TestBuild_linux_x64
• Failed projects: redist.csproj (247.1s), dotnet-sdk.proj (249.9s)
• Exit: build failure propagated from the DownloadBundledComponents target via the DownloadFile task
• All 23 other legs across AoT (macOS x64/windows x64), TestBuild (linux x64/arm64, macOS x64/arm64, windows x64), TestAsTools (windows x64), and FullFramework (windows x64) reported no errors.

All MSBuild errors (1)

Code	Project	File:Line	Message
(none — runtime exception, no MSBuild diagnostic code)	redist.csproj	RestoreLayout.targets:314	HttpRequestException/HttpIOException: The response ended prematurely during DownloadFile in target DownloadBundledComponents
