I am creating vsix project that is Editor Classifier (a template for managing editor content). I executed the project, the plugin was installed in that experimental window. It always worked properly. but when I install another plugin (e.g. a menu command or a tool window), the previous plugin overlaps the current one.
I tried to uninstall the plugin directly from experimental window from Manage Extentions menu. All the previous extensions got uninstalled properly by doing this, but when I try to reinstall them, It could not be installed.
