ASP.NET There is a problem with your selected data store

go to
C:\Windows\Microsoft.NET\Framework\v4.0.30319 and run aspnet_regsq,exe

Then

u try editing the web.config file...

there is lot more to do with that..
hav u created ur own database for your application. If so you have to
give the connection string for that database.

This is my webconfig file. see this and try. I tried for about 3 days
to that.

if u didn't include the roleManager then we can't create the roles and
it states and error message saying "website not configured to enable
roles"
