FindToolWindowAsync (like ShowToolWindowAsync) - More probably this is a VS bug because it uses CreateToolWindow and this failed only when ToolPane is not activated after starting VS IDE.

That is, I have no problems when CreateToolWindow is used from different thread outside InitializeAsync() from our plugin with JoinableTaskFactory.

protected override async Task InitializeAsync(CancellationToken ct, IProgress<ServiceProgressData> progress)
{
    await this.JoinableTaskFactory.SwitchToMainThreadAsync(ct);

    // UI thread

    CreateToolWindow(typeof(StatusToolWindow), 0); // <<< await FindToolWindowAsync()

Same result for updated VS 16.1.2

For today, I think I will use an old FindToolWindow() byound InitializeAsync() thread. After cb8d9d8 works well.

Any suggestions are welcomed.
