Thank you for your interest in the .NET 4.0 Framework enabled to use Software Transactional Memory (STM.NET). The incubation has concluded. 

We appreciate all the feedback we have received since STM.NET was released; it truly helps us define our product decisions and technology investments. STM provides ease-of-use and safe, compositional synchronization. Both MSR and the parallel-programming team in Microsoft will continue to research and incubate various technologies to help the developer safely and easily scale their application; your input is important.

You can follow future efforts at the Parallel Computing Developer Center. We will continue to have our blog Transactional Memory.  Our STM.NET forum will be locked but you can participate in the Parallel Extensions to .NET Forum.

While the .NET download and samples have been removed, you can still download the STM Programmer’s Guide.
