I’m encountering a problem in Visual Studio 2010.Problem began after I hibernated my computer,and other day when i opened Visual Studio had problems with finding my existing projects.
After problem occurred I tried to reestablish my projects by using Open Existing Project dialog,an error message appears like below

c:\windows\microsoft.net\framework\v4.0.30319\Microsoft.Common.targets(1347,130):
The project file could no be loaded.The 'FindDependencies'
start tag on line 1347
position 14 does not match the end tag of '_FindDependencies'.
Line 1347, position 130
I tried to disable extensions,delete my current settings but no solution
How can solve this problem ?
File is probably corrupted. Your start tag is different than it should be (missing underscore).
I have this in my .NET targets file:
I recommend reinstalling .NET 4.0, you do not know what else can be wrong.
