 When `GetLeisureHours` is called from within an await expression in the `ShowTodaysInfo` method, the await expression retrieves the integer value (the value of `leisureHours`) that's stored in the task returned by the `GetLeisureHours` method. For more information about await expressions, see [await](../../../../csharp/language-reference/keywords/await.md).  
 
-You can better understand how this happens by separating the call to `GetLeisureHours` from the application of `await`, as the following code shows. A call to method `GetLeisureHours` that isn't immediately awaited returns a `Task<int>`, as you would expect from the declaration of the method. The task is assigned to the `integerTask` variable in the example. Because `integerTask` is a <xref:System.Threading.Tasks.Task%601>, it contains a <xref:System.Threading.Tasks.Task%601.Result> property of type `TResult`. In this case, TResult represents an integer type. When `await` is applied to `integerTask`, the await expression evaluates to the contents of the <xref:System.Threading.Tasks.Task%601.Result%2A> property of `integerTask`. The value is assigned to the `ret` variable.

 > [!IMPORTANT]
 >  The <xref:System.Threading.Tasks.Task%601.Result%2A> property is a blocking property. If you try to access it before its task is finished, the thread that's currently active is blocked until the task completes and the value is available. In most cases, you should access the value by using `await` instead of accessing the property directly. <br/> The previous example retrieved the value of the <xref:System.Threading.Tasks.Task%601.Result%2A> property to block the main thread so that the `ShowTodaysInfo` method could finish execution before the application ended.
