 An async method can return any type that has an accessible `GetAwaiter` method that returns an instance of an *awaiter type*. In addition, the returned type must match the type of the parameter of `SetResult` and returned type of the `Task` property on the type specified by the <xref:System.Runtime.CompilerServices.AsyncMethodBuilderAttribute?displayProperty=nameWithType> attribute. You can learn more in the article on [Attributes read by the compiler](../language-reference/attributes/general.md#asyncmethodbuilder-attribute) or the C# spec for the [Task type builder pattern](~/_csharpstandard/standard/classes.md#15142-task-type-builder-pattern).

Generalized async return types enable the compiler to generate `async` methods that return different types. Generalized async return types enabled performance improvements in the .NET libraries. Because <xref:System.Threading.Tasks.Task> and <xref:System.Threading.Tasks.Task%601> are reference types, memory allocation in performance-critical paths, particularly when allocations occur in tight loops, can adversely affect performance. Support for generalized return types means that you can return a lightweight value type instead of a reference type to avoid more memory allocations.

 .NET provides the <xref:System.Threading.Tasks.ValueTask%601?displayProperty=nameWithType> structure as a lightweight implementation of a generalized task-returning value. The following example uses the <xref:System.Threading.Tasks.ValueTask%601> structure to retrieve the value of two dice rolls.
