How to add user control in Sitecore? -

I have created a user control outside of Sitcom CMS, now I would like to import it into Sitcom.

You can do that in core database

it tells you:

Log in the Sitcom and select the core database.
Add a new app below the sitcom & gt; Content & gt; Application - In the newly created element, search the data process in the "Application" input field and fill the application path. This example can be a \ MyCompanyName \ Administration \ Default.aspx
Select a display name and icon for the application.
Next go to the sitecore - & gt; Content - & gt; Document & amp; Settings - & gt; All users (if all users need access to it) - & gt; Start menu - & gt; Add the left and your new shortcut.

If you have created an XAML application, you can find more information.
