ROSLYN.RELIABILITY.CA2007 : Consider calling ConfigureAwait on the awaited task (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.RELIABILITY.CA2007 : Consider calling ConfigureAwait on the awaited task (C#)

See Roslyn-Detected C# Warning Classes for more information.

Summary

When an asynchronous method awaits a Task directly, continuation occurs in the same thread that created the task. Consider calling Task.ConfigureAwait(Boolean) to signal your intention for continuation. Call ConfigureAwait(false) on the task to schedule continuations to the thread pool, thereby avoiding a deadlock on the UI thread. Passing false is a good option for app-independent libraries. Calling ConfigureAwait(true) on the task has the same behavior as not explicitly calling ConfigureAwait. By explicitly calling this method, you're letting readers know you intentionally want to perform the continuation on the original synchronization context.

This check corresponds to Roslyn rule CA2007. For full rule details, see the Microsoft website: CA2007.
