I am getting an error while trying to open aspnetdb.mdf and PTracker.mdf .I am using SQ: Server 2008 R2 express. Here is a part of the error message:
cannot be opened because it is version 655. This server supports version 611 and earlier. A downgrade path is not supported
According to this info version 611 is SqlServer 2005 Express and NOT using SqlServer 2008 R2. http://weblogs.sqlteam.com/dang/archive/2011/07/17/internal-sql-server-database-version-numbers.aspx
Plaease make sure that your selected SqlServer Express, in Visual Studio 2010 - goto Tools - Options - Database Tools - Data Connections is set to an instance of SqlServer 2008 Express R2 and you may have to edit the connection string in web.config too.
Jonny is corrrect. And I just went through this too, because I reinstalled Win7 on my laptop. What a pain!
My frustration (and solution) is here:
Thanks for the info. But since the solution involved reinstallation(s), I thought I would try that as a last resource. So I looked for more info from the web. I found this article which enable me to open protracker.mdf file from sql server 2008 express.
After that I tried similar approach to connect from Visual studio 2010 and it worked. Then I modified the connection string to use correct server name. Then I was able to run project tracker successfully.
