 An async method can return any type that has an accessible `GetAwaiter` method that returns an instance of an *awaiter type*.

You can learn more in the article on [Attributes read by the compiler](../language-reference/attributes/general.md#asyncmethodbuilder-attribute) or the feature spec for [Task like return types](~/_csharplang/proposals/csharp-7.0/task-types.md).

 .NET provides the <xref:System.Threading.Tasks.ValueTask%601?displayProperty=nameWithType> structure as a lightweight implementation of a generalized task-returning value. To use the <xref:System.Threading.Tasks.ValueTask%601?displayProperty=nameWithType> type, you must add the `System.Threading.Tasks.Extensions` NuGet package to your project. The following example uses the <xref:System.Threading.Tasks.ValueTask%601> structure to retrieve the value of two dice rolls.
