🔍 Build Failure Analysis

Summary — The dependency bump of Microsoft.DotNet.ProductConstructionService.Client from 1.1.0-beta.26374.1 to 1.1.0-beta.26413.1 introduced a breaking API change in GetBuildAsync: a new bool? includeAssetLocation parameter was inserted as the second positional argument (before CancellationToken), causing two CS1503 type-mismatch errors in PublishBuildToMaestro.cs.

Root cause: GetBuildAsync signature change — new bool? parameter before CancellationToken

The new Microsoft.DotNet.ProductConstructionService.Client package changed IBuildClient.GetBuildAsync from:

Task<Build> GetBuildAsync(int id, CancellationToken cancellationToken = default);

to:

Task<Build> GetBuildAsync(int id, bool? includeAssetLocation = default, CancellationToken cancellationToken = default);

The two call sites in PublishBuildToMaestro.cs pass cancellationToken as the second positional argument, which now binds to bool? instead of CancellationToken.

Affected errors

Code	File:Line	Message
CS1503	PublishBuildToMaestro.cs:362	Argument 2: cannot convert from System.Threading.CancellationToken to bool?
CS1503	PublishBuildToMaestro.cs:380	Argument 2: cannot convert from System.Threading.CancellationToken to bool?

Proposed fix

In src/Microsoft.DotNet.Build.Tasks.Feed/src/PublishBuildToMaestro.cs, change both call sites to use the named cancellationToken: parameter (this also passes null/default for the new includeAssetLocation parameter, which is the appropriate behavior):

// Line 362
-                    producingBuild = await client.Builds.GetBuildAsync(asset.BuildId, cancellationToken);
+                    producingBuild = await client.Builds.GetBuildAsync(asset.BuildId, cancellationToken: cancellationToken);

// Line 380
-            var build = await client.Builds.GetBuildAsync(buildId.Value, cancellationToken);
+            var build = await client.Builds.GetBuildAsync(buildId.Value, cancellationToken: cancellationToken);

Note: PublishBuildToMaestro.cs is not part of this PR's diff — the fix needs to be committed separately (e.g., pushed to this branch by a maintainer, or merged as an additional commit alongside the dependency update).
