.NET Framework 4.5 Built-In Activity Library

.NET Framework 4.5 introduced a new activity library with expanded functionality. The types of activities include the following:

• Control Flow

• Flowchart

• State Machine

• Messaging Activities

• Runtime

• Primitives

• Transaction

• Collection

• Error Handling

• Migration

The activities in the built-in activity library can be composed into workflows, or used alongside custom activities. The activities in the built-in activity library are sealed; they are not intended to be used to create new functionality through inheritance.
