SYSLIB diagnostics for p/invoke source generation
The following table shows the diagnostic IDs for platform-invoke (p/invoke) source-generation analyzers in .NET 7 and later versions. SYSLIB1054 automatically alerts you to places that you can use source generation to generate p/invoke marshalling code at compile time. The remaining diagnostics alert you to errors related to usage of the source generator.
| Diagnostic ID | Title | Descriptions |
|---|---|---|
SYSLIB1050 |
Invalid LibraryImportAttribute usage. | - Method '{0}' should be 'static', 'partial', and non-generic when marked with 'LibraryImportAttribute'. P/Invoke source generation will ignore method '{0}'. - Method '{0}' is contained in a type '{1}' that is not marked 'partial'. P/Invoke source generation will ignore method '{0}'. - The configuration of 'StringMarshalling' and 'StringMarshallingCustomType' on method '{0}' is invalid. |
SYSLIB1051 |
The specified type is not supported by source-generated p/invokes. | - The generated source will not handle marshalling of parameter '{1}'. - The generated source will not handle marshalling of the return value of method '{1}'. |
SYSLIB1052 |
The specified configuration is not supported by source-generated p/invokes. | - The configuration is not supported by source-generated P/Invokes. If the specified configuration is required, use a regular DllImport instead.- The specified configuration for parameter '{1}' is not supported by source-generated P/Invokes. - The specified configuration for the return value of method '{1}' is not supported by source-generated P/Invokes. - The specified value for '{1}' is not supported by source-generated P/Invokes. - The specified marshalling configuration is not supported by source-generated P/Invokes. |
SYSLIB1053 |
The specified LibraryImportAttribute arguments cannot be forwarded to DllImportAttribute. | '{0}' has no equivalent in 'DllImportAtttribute' and will not be forwarded. |
SYSLIB1054 |
Use LibraryImportAttribute instead of DllImportAttribute to generate p/invoke marshalling code at compile time. | |
SYSLIB1055 |
Invalid CustomMarshallerAttribute usage. | |
SYSLIB1056 |
The specified native type is invalid. | |
SYSLIB1057 |
The marshaller type does not have the required shape. | |
SYSLIB1058 |
Invalid NativeMarshallingAttribute usage. | |
SYSLIB1059 |
The marshaller type does not support an allocating constructor. | |
SYSLIB1060 |
The specified marshaller type is invalid. | |
SYSLIB1061 |
The marshaller type has incompatible method signatures. | |
SYSLIB1062 |
The project must be updated with <AllowUnsafeBlocks>true</AllowUnsafeBlocks>. |
