I have a project with a bunch of controls. All of those controls inherit from a single base class: ControlBase. ControlBase inherits from UserControl.
Every time I reference one of my custom controls in ASP.Net markup, I get the following error and warning
Id attribute is invalid for tags that are not inherited from Control
Runat attribute is neglectible for tags that are not inherited from Control
ReSharper should check further up the chain to see if the attributes are valid or not neglectible (is neglectible a word? I think neglectable is).
