at Microsoft.VisualStudio.Design.Serialization.CodeDom.VSCodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager serializationManager)
at System.ComponentModel.Design.Serialization.BasicDesignerLoader.BeginLoad(IDesignerLoaderHost host)

error list say this:
Warning 1 Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)) 0

if i ignore the error my form goes blank so what i wanna know is how do i go about fixing this with the information provided as i have no clue.

I did the same deleteing of the ncb and it solved the problem. Wierd Science i guess.
