Parser Error Message: An attempt to
attach an auto-named database for file
D:\Projects\Damnation\Damnation.Website\Damnation.Website.Tracker\BugNET_WAP\App_Data\aspnetdb.mdf
failed. A database with the same name
exists, or specified file cannot be
opened, or it is located on UNC share.

Why could this be happening? My connection string doesn’t use |DataDirectory|, it is:

<connectionStrings>
  <add name="BugNET" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=dnmain;Integrated Security=True;"/>
</connectionStrings>

I get this error when I try to load default.aspx, after installing BugNET.

Apparently, and certainly for some obscure reason. There is a mistery connection string coming from… nowhere.

Problem solved adding a <clear/> tag.

<connectionStrings>
  <clear/>
  <add name="BugNET" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=dnmain;Integrated Security=True;"/>
</connectionStrings>
