Question

I am using the create user wizard of C# asp.net 4. I want to change its default database (i.e. ASPNETDB.mdf) to my own created database (i.e. test.mdf).

How can I do this? and one more thing.

Answer 1

2 step required .

First need to run aspnet_regsql.exe tool which is located in [YouWinDrive]:\Windows\Microsoft.NET\Framework\v2.0.50727 and in this wizard while you target your arbitrary database create necessary objects .

Step2 : you need to config your asp.net membership provider . as you may know web.config file inherites from Machine.config file which is locatd in [YouWinDrive]:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG

if you look at that file you will find out Default AspNetSqlMembershipProvider is targeted in sqlserver express and aspnetDB :

    <membership>
        <providers>
            <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="LocalSqlServer" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" applicationName="/" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10" passwordStrengthRegularExpression=""/>
        </providers>
    </membership>

So you need to override this membership in your web.config file like this :

<membership defaultProvider="MyMembershipProvider">
            <providers>
                <add name="MyMembershipProvider"
                     type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
                     connectionStringName="YourConnectionToArbitraryDatabase"
                     enablePasswordRetrieval="true"
                     enablePasswordReset="true"
                     requiresQuestionAndAnswer="true"
                     applicationName="YourAppName"
                     requiresUniqueEmail="false"
                     passwordFormat="Encrypted"
                     maxInvalidPasswordAttempts="5"
                     minRequiredPasswordLength="5"
                     minRequiredNonalphanumericCharacters="0"
                     passwordAttemptWindow="10"
                     passwordStrengthRegularExpression=""/>
            </providers>
        </membership>

and you can change it as you would like .
