ASP. Features need application Service database support

The build Web program appears as shown in the errorreason programs use the following ASP . NET Attributes

• membership (The SqlMembershipProvider Class).

• profile (The SqlProfileProvider Class).

• web Events (The SqlWebEventProvider Class)     

By default, each of the SQL Server provider stores data in an automatically generated database using a local Microsoft SQL Se RVer Express installation. Each feature can is used individually, or in conjunction with other features. For example, you could use role management by itself or in conjunction with the user information managed by the membership Feature

There are two ways to solve this problem

1:asp.net includes a tool for installing the SQL Server database used by the SQL Server providers (aspnet_regsql.exe)

2:web.config
