So, WSRF.NET implements the support for RPs and Lifetime on *standard* 
.NET, such that developers will not have to implement the primitives, 
can easily deploy the great abstraction that they represent, and can 
instead focus on higher-level application code.

Furthermore, it will allow us to model the world the WSRF-way with the 
confidence that those developers do not face any impedance mismatch on 
the .NET platform.

Those are only the masochistic-type of programmers who do not (want to) 
look for available http-libraries that implement the stack for them...

PS. (...be careful not to give arguments in support of wsrf and wsrf.net 
;-) )
