What is "UseRANU" parameter in Visual Studio

I have created a package in VS2010 RC using the MPF (Managed Package Framework) and I get the following error. Can somebody help me out with this ??

Th开发者_StackOverflowe "UseRANU" parameter is not supported by the "VsTemplatePaths" task. Verify the parameter exists on the task, and it is a settable public instance property.

The "VsTemplatePaths" task could not be initialized with its input parameters.

It seems that your .vstemplate contains a "UseRANU" parameter for the VsTemplatePaths task, which is obviously invalid. Open the .vstemplate and remove that parameter.

I was using a wrong MPF. There are two, one for VS2008 and another for VS2010. I changed the MPF and the problem never occurred. Thanks for your answers
