Parameter type. The constructor deliberately prevents the use of value types. Because ICommand takes an object, having a value type for T would cause unexpected behavior when CanExecute(null) is called during XAML initialization for command bindings. Using default(T) was considered and rejected as a solution because the implementor would not be able to distinguish between a valid and defaulted values. Instead, callers should support a value type by using a nullable value type and checking the HasValue property before using the Value property.

Initializes the attribute with the specified return value condition.

The return value condition. If the method returns this value, the associated parameter may be null.

Gets the return value condition.

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).

Initializes a new instance of the class with the specified member types.
