This is partially correct as you cannot directly delete a component. A component is removed from the project when its attached resource (file/registry) is deleted.
The solution is to move the components from the feature, once its empty you can delete it.
yes you are right . it dont have any components attached inside the "MainFeature" because that it is preloaded . but my only problem is i cant make it be removed . in someway how can i delete or remove this "MainFeature" ? .
,tnx sir for ur reply but how exactly can i go to the context you are saying ? . i seem to not understand the correct steps in deleting a unnecessary Feature.
