| Title | Method uses runtime marshalling when DisableRuntimeMarshallingAttribute is applied |
| Category | Interoperability |
| Fix is breaking or non-breaking | Non-breaking |
| Enabled by default in .NET 8 | As suggestion |
A method uses runtime marshalling, and runtime marshalling is explicitly disabled.
If a method uses runtime marshalling when runtime marshalling is disabled, it can cause unexpected behavior differences at run time due to different expectations of a type's native layout.
Enable runtime marshalling or use features like sizeof and pointers to ensure accurate results.
Don't suppress a warning from this rule.
The following code snippet shows a violation of CA1421:
:::code language="csharp" source="snippets/csharp/extra-rules/ca1421.cs"::: :::code language="vb" source="snippets/vb/extra-rules/ca1421.vb":::
To fix the violation, remove the xref:System.Runtime.CompilerServices.DisableRuntimeMarshallingAttribute attribute on the assembly.
