CloseActivity()

Indicates to the workflow runtime that the currently executing activity should transition to the Closed state.

Equals(Object)

Determines whether the specified object is equal to the current object.

GetService(Type)

Returns a service of the specified type.

GetService<T>()

Returns a service provider of the specified Type.

GetType()
