The name of the parameter with which corresponds. Attribute used to indicate a source generator should create a function for marshalling arguments instead of relying on the runtime to generate an equivalent marshalling function at run-time. This attribute is meaningless if the source generator associated with it is not enabled. The current built-in source generator only supports C# and only supplies an implementation when applied to static, partial, non-generic methods. Initializes a new instance of the .
