Microsoft recently released the developer preview of the next version Windows as well as a developer preview of Visual Studio 11 for building apps on the new version of Windows. Some of you may have noticed that the “New Item” template for creating a WCF Data Services isn't working correctly (this is pre-release “preview” software after all). We have created a fix for these templates that you can use to unblock creating a WCF Data Service. The details of apply the fix are below – keep in mind this version of Visual Studio is a preview release only and the fix should only be used with that version of Visual Studio and should not be applied to any other beta/RTM version of Visual Studio.

Installation Instructions for Updates Templates:

1. Download and unzip the templates attached to this post.

2. Install the new templates. There are 4 templates to install, and installing them simply requires that you copy the attached templates over the ones in the Visual Studio directory. The names of the templates and the location to copy them are in the table below (each location is relative to the base Visual Studio install directory).

Template Location <Program Files>\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\CSharp\Web\1033 <Program Files>\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\VisualBasic\Web\1033 <Program Files>\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\Web\CSharp\1033 <Program Files>\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\Web\VisualBasic\1033

3. Update Visual Studio.
     a. Close any active instances of Visual Studio 2011. 
     b. Open an elevated Visual Studio 2011 Developer Command Prompt. You can find a tile for this from the start screen, right-click the tile, select the Advanced button and select Run as administrator. 
     c. In the developer command prompt enter the command “devenv /installvstemplates”
     d. Wait for the command to complete and then start Visual Studio and the Item Templates should be working.

If you have any comments or questions on using WCF Data Services in the developer preview of Visual Studio please don’t hesitate to send them to us.
