Solution 1

Your error has its solution.. Make sure that in your database is not opened anywhere else or say you can't keep two databases with same name in one application folder.. This leads to conflicts...

Hope this info will help you..

First of all, Share your code here and I'll not download any file.

Perhaps according to your error your solution is here-
An attempt to attach an auto-named database for file ... failed[^]

An attempt to attach an auto-named database ....\aspnetdb.mdf failed[^]
