Managed implementation of the blocks as defined in the Language Specification for Blocks[1]. Even if the implementation strictly follows the Block Implementation Specification[2], it is restricted to global block for the moment.
The block bridging allow a delegate function or action to be marshalled as a native block. Its implementation points to a proxy invoker that will forward the native block invocation to the delegate function or action.
Currently, any delegate can be passed to create a block. For example:
| Delegate | Equivalent block signature |
|---|---|
| Action | void (^)() |
| [!:Action{T1,T2,T3}] | void (^)(T1, T2, T3) |
| [!:Func{TResult}] | TResult (^)() |
| [!:Func{T1,T2,TResult}] | TResult (^)(T1, T2) |

 | Block(Delegate) |
Initializes a new instance of the Block class.
|
 | BlockInvoker |
Gets the block invoker.
|
 | Dispose()()()() |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
|
| Dispose(Boolean) |
Releases unmanaged and - optionally - managed resources
|
| Equals(Object) | (Inherited from Object.) |
| Finalize()()()() |
Releases unmanaged resources and performs other cleanup operations before the
Block is reclaimed by garbage collection.
(Overrides Object.Finalize()()()().) |
| GetHashCode()()()() |
Serves as a hash function for a particular type.
(Inherited from Object.) |
| GetType()()()() |
Gets the Type of the current instance.
(Inherited from Object.) |
| Invoker |
Gets the invoked delegate.
|
| MemberwiseClone()()()() |
Creates a shallow copy of the current Object.
(Inherited from Object.) |
| NativePointer |

|
| ToString()()()() |
