Attribute constructor has a 'ByRef' parameter of type '<typename>'; cannot use constructors with byref parameters to apply the attribute
An attribute is applied to a programming element using an attribute constructor that takes a ByRef parameter.
Attributes are applied at compile time, and the compiler needs concrete values to pass to the attribute constructor. A ByRef parameter takes a pointer to a value, which cannot be evaluated at compile time.
You can define an attribute constructor that takes a ByRef parameter, and you can use it for purposes such as inheriting, but when you apply the attribute you must use a constructor that does not take any ByRef parameters.
Error ID: BC36006
To correct this error
- Apply the attribute using a constructor that does not take any ByRef parameters, or do not apply the attribute at all.
