Indicates that certain members on a specified are accessed dynamically, for example through .

This allows tools to understand which members are being accessed during the execution of a program. This attribute is valid on members whose type is or . When this attribute is applied to a location of type , the assumption is that the string represents a fully qualified type name. When this attribute is applied to a class, interface, or struct, the members specified can be accessed dynamically on instances returned from calling on instances of that class, interface, or struct. If the attribute is applied to a method it's treated as a special case and it implies the attribute should be applied to the "this" parameter of the method. As such the attribute should only be used on instance methods of types assignable to System.Type (or string, but no methods will use it there).

When applied to an attribute class, instructs the compiler to flow applications of that attribute, from source code down to compiler-generated symbols. This can help IL-based analysis tools.

One example where this attribute applies is in C# primary constructor parameters. If an attribute marked with gets applied to a primary constructor parameter, the attribute will also be applied to any compiler-generated fields storing that parameter.

Initializes a new instance of the class.

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.
