New Post: DB connection issue

Hi, I solved the issue before of reading your post and the linked page, by attaching manually the mdf database in app_data and naming it BugNet. To avoid to edit permissions I copied it into the MSSQL data folder.
I edit also the ConnectionString in this way:

<add name="BugNET" connectionString="Data Source=localhost;Initial Catalog=BugNet;Integrated Security=True;" providerName="System.Data.SqlClient" /> 

Although I didn't find it in MSDN or other official Microsoft documentation, I read on many forums that attachDbFileName in connectionstrings is allowed only in the EXPRESS version of SqlServer. For example you can find it here:

I don't know if this is right or wrong, but attaching manually the DB and modifying the connectionstring as above my installation works fine! :)
However... thank you for your response! ;)
