Marty Humphrey and his team have released an .NET implementation of many of the popular services provided by the Globus Toolkit.

Globus Interoperability for the .NET Platform

This site provides client and server implementations of two of the most popular services provided by the Globus Toolkit. The Globus Toolkit v. 4 (GT4) implementation of GridFTP, a data transfer protocol, and GRAM, a job execution protocol, are widely deployed in many scientific grids. We present implementations of both GridFTP and GRAM, services and clients, that run on the Microsoft .NET Framework and are interoperable with their GT4 counterparts.
