Cannot Create BizTalk Project from VS 2008

After a new installation of BizTalk 2009 with all the prerequisites steps from microsoft i was not able to create a new biztalk project from Visual studio 2008.When you try to create a new Biztalk project using

File -> New Project -> Any BizTalk Project Type

You get the error message: Creating project ‘project name’… project creation failed.

most of the users tells me reinstallation of BizTalk that was not a good solution for me as i have been fixing many errors during the BizTalk installation and i don't want to go through the same process again and i need to finish with this implementation as it is dependent on few other projects. oh i am stuck again.

again the registry change . though it is not preferred always if you know what you are doing it then go for it. it could come handy.here is what i did. search for {FAE04EC0-301F-11d3-BF4B-00C04F79EFBC} under projects

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Projects\{FAE04EC0-301F-11d3-BF4B-00C04F79EFBC}]

the value for "PossibleProjectExtensions"="csproj" change it to "csproj;btproj" remove the "

for 64 bit versions of Visual Studio the path is

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0\Projects\{FAE04EC0-301F-11d3-BF4B-00C04F79EFBC}

now restart the Visual Studio it works. what i came to know is Biztalk installation modifies the reg value to register its project extension with the C# project factory.thanks to the blogger.
