The June 2008 CTP of the Managed Services Engine is now available for you to download from CodePlex. For those not familiar with MSE, it is a framework for developing Enterprise SOA :
The MSE fully enables service virtualization through a Service Repository, which helps organizations deploy services faster, coordinate change management, and maximize the reuse of various service elements. In doing so, the MSE provides the ability to support versioning, abstraction, management, routing, and runtime policy enforcement for Services.
Originally developed by MCS, the MSE is now freely available for download on our Open Source repository at CodePlex.
