Ok, here is my current connection string. I now throws the error:

Invalid value for key attachdbfilename

Connection string: (this is where the rest of my databases are located)

<connectionStrings>

<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA;Initial Catalog=aspnet-learning1-20130420131735;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-learning1-20130420131735.mdf" />

<add name="WingtipToys"

connectionString="Data Source=C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA;AttachDbFilename=|DataDirectory|\wingtiptoys.mdf;Integrated Security=True"

providerName="System.Data.SqlClient " />

Havent moved my VS project yet.

If I created the folder you suggested (c:\SQLData) and put my project there will it clear the attachdbfilename error?
