+## Cause
+
+A `Task` whose continuation behavior has not been configured is awaited.
+
+## Rule description
+
+The continuation behavior for a `Task` should be configured by calling `ConfigureAwait` prior to awaiting the task. This
+diagnostic is reported if an `await` expression is used on a `Task` that has not been configured.
+
+## How to fix violations
+
+To fix a violation of this rule, use `ConfigureAwait(false)` or `ConfigureAwait(true)` as appropriate for the context of
+the asynchronous operation.

+## How to suppress violations

+```csharp
+#pragma warning disable UseConfigureAwait // Use ConfigureAwait
+await Task.Delay(1000);
