Data Services Release Plan Update

DB Blogs

We’ve heard a lot of feedback since we first discussed our plans to create v1.5 of Data Services (  Since that time we’ve been busy improving the quality of the product, adding features and solidifying our release plans.   The remainder of this post discusses our target release plan for the next version of Data Services and when the final bits will be available.  

One area we heard consistent feedback on was the desire to limit the number of Data Service releases where possible.  To address this need we have decided to change the ship vehicle for the release to be an in-place update of the data services binaries that shipped with the .NET Framework 3.5 SP1 (instead of a SxS release as was the case for the v1.5 CTP1 release).  The release will ship as a redistributable update to the .NET Framework 3.5 SP1, which will include enhanced data services runtime assemblies and an updated datasvcutil.exe command line tool.  As you’d expect, since the release is shipping as an update to the .NET Framework 3.5 SP1, all the binaries shipped with the release will be named as they were in the .NET Framework 3.5 SP1 release (i.e. System.Data.Services.*.dll).  In addition to shipping an update to the .NET Framework 3.5 SP1, we’ll release a new Silverlight 3-compatible client library and the .NET-related client and server features from the .NET 3.5 SP1 update release will be directly included in the subsequent .NET Framework 4.0 release.   

We will also be changing the release name to better convey that it is an in-place update to the .NET Framework 3.5 SP1. We’ll be dropping “v1.5” from the name and simply calling it  the Data Services Update for the .NET Framework 3.5 SP1

We aren’t yet ready to talk about a specific release date (we’re getting close 🙂 ), but we are focused on this calendar year as our target window to release the update to the .NET Framework 3.5 SP1.  After that, as mentioned above, the feature set will be directly included in the subsequent .NET Framework 4 release.

The feature set for the release will include the features we have already discussed on the data services blog ( & )
