%windir%\Microsoft.NET\Framework\v4.0.30319

Find the aspnet_regsql.exe file and double-click on it to open the wizard.

3. Follow the Wizard:
The wizard will guide you through the process of configuring the stored procedures and objects in the database.

4. Roles and ASP.NET MVC:
Ensure that roles are enabled in your ASP.NET MVC project prior to creating the aspnet identity table.

5. Verify Database Changes:
After running aspnet_regsql.exe, refresh the database connection in your application and verify that the necessary stored procedures and objects have been created.
