that issue made me crazy, I have done a project named Project1 and I have used Microsoft visual basic power packs for drawing rectangles .
then I have added that project to the Team foundation server under project2 and I Have added the Dlls and then i open it again from the server connection , then suddenly the error appears that the form is missing namespace reference and the Power Pack not showing in the toolbox.
I have tried it from other PC by connecting to the TFS then it works fine.
What is more strange , if I open Project1 it shows the PowerPack in the toolbox, but if I open project2 by connecting to the TFS it doesn't show..
I have tired a lot of adding a references manually , I tried to register the assemblies but all not working...
any suggestions ?
