Original post content:
In web. config
Add

XML Code

      <  Anonymousidentification  Enabled  = "True"  />    <  Profile  Enabled  = "True" >    <  Properties  >    <  Add  Name  = "Mynewproperty"  Allowanonymous  = "True"     />    </  Properties  >   </  Profile  >   

In each page. aspx. CS

C # code

    Access through profile. mynewproperty

Can this be achieved smoothly on other machines?

However, my machine, for any page in the project, appears during debugging:
UserCodeHttpexception not handled
Cannot connect to the SQL Server database.

When browsing directly:
Do not generate user instances in SQL Server. Use sp_configure 'user instances enabled' to generate a user instance.
