| ## Marshaller shapes | ||
|
|
||
| The set of methods that the marshalling generator expects from a custom marshaller type is referred to as the *marshaller shape*. To support stateless, static custom marshaller types in .NET Standard 2.0 (which doesn't support static interface methods), and improve performance, interface types are not used to define and implement the marshaller shapes. Instead, the shapes are documented in the [Custom marshaller shapes](custom-marshaller-shapes.md) article. The expected methods (or shape) depends on the whether the marshaller is stateless or stateful, and whether it supports marshalling from managed to unmanaged, unmanaged to managed, or both (declared with `CustomMarshallerAttribute.MarshalMode`). The .NET SDK includes analyzers and code fixers to help with implementing marshallers that conform to the required shapes. |
