Problem
I am trying to add a user control in Web.Config file as below,
It gives me following error,
Configuration Error: The relative virtual path 'MyUserControl.ascx' is not allowed here.
Solution
To resolve this issue, move your WebUserControl from root directory to a sub directory. For example in my case, I would copy MyUserControl.ascx to sub folder "Controls". So my Web.Config entry should look like below.
Notice how value of src parameter is changed.
~ indicates relative path from root folder.
This is one of the limitation of ASP.Net application. It does not allow you to register user control in Web.Config file unless it's in a subfolder.
