Unable to open a specific .tstest file with the desirable editor in VS2010 (using Telerik TS plugin, 2012.2.1527.0 version).
When the file is double-clicked it is being opened with the XML editor when it should be opened with WebAii Test Editor.

To work around, do tghe following:

Right click over the .tstest file --> Open With... --> select "WebAii Test Editor" --> click on "Set as Default" --> OK.

The files opens with the WebAii Test Editor as expected then, but if we close the tab and double-click the .tstest file again, it will re open again with the XML editor. If we select "Open With..." again, we see that the WebAii Test Editor is set as default already, but it is not working as expected for that specific file (it does for the others).


------ Solution

1) Close Visual Studio.
2) Open the .csproj file for the project.
3) Find the test having the issue.
4) Remove the XML associated with it entitled: "<SubType>Designer</SubType>"
5) Save file and reload project.
6) Attempt to double click .tstest in UI again.  Opens with Webaii Editor as expected.
