Field 'ConsoleRunnerPackage' not found.

Error message

Field 'ConsoleRunnerPackage' not found.

What it means

DotMemoryDiagnoser.GetRunnerPath reflects into JetBrains.Profiler.SelfApi's DotMemory type to find the private static field 'ConsoleRunnerPackage'. It throws when that field no longer exists, meaning the bundled SelfApi package layout has changed from what this BDN build expects. GetRunnerPath runs from SnapshotProfilerBase.Init right after InitTool (DotMemory.InitAsync) succeeds.

Solutions

1. Use the JetBrains.Profiler.SelfApi version that ships with / is referenced by your BenchmarkDotNet.Diagnostics.dotMemory build (do not independently upgrade it).
2. Clear the cached prerequisite (delete the SelfApi download cache) so InitAsync re-fetches the expected package.
3. Upgrade BenchmarkDotNet to a release that matches the SelfApi layout you have installed.
4. If patching BDN, update GetRunnerPath to match the current SelfApi field/method names.

// Init() already retries InitTool 5x; GetRunnerPath failures surface there. At the call site:
try { diagnoser.Handle(...); }
catch (InvalidOperationException ex) when (ex.Message.Contains("ConsoleRunnerPackage"))
{
    log.Error("dotMemory SelfApi layout mismatch - align JetBrains.Profiler.SelfApi version with your BDN build.");
}

When it happens

Trigger: The loaded JetBrains.Profiler.SelfApi assembly (downloaded/updated by InitAsync, or pinned via NuGet) is a version where 'ConsoleRunnerPackage' was renamed, moved, or removed. Happens after a SelfApi package upgrade, a forced NuGet override, or a corrupted/again-downloaded prerequisite.

Common situations: Upgrading the dotMemory SelfApi dependency independent of BenchmarkDotNet; offline/cached prerequisite that is a different build; running against a preview/insider build of the JetBrains profiler.
