When i open the designer it gives me this error.
Could not load file or assembly 'Windows, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
if i ignore the error and try to add an item (I.E. button, label, etc.) it crashes and gives me the same error. I saw some things on how it was the Entity Framework but theres not a way to update that that I've found.
Edit: It wasn't a runtime error or a compile error it only kept the designer from working.
