When a control is referenced externally from the toolbox, the System prompts: Universe cannot parse the Assembly: System. design, Version = 2.0.0.0, Culture = neutral, PublickeyToken = b03f5f7f11d50a3a. After searching online for half a day, I finally found a solution, this problem occurs because I chose the framework when creating a new project. net4.0, however. net4.0 contains two types during installation, as if the default is. net4.0 Client Profile. When added below, the above error is reported.

 

Solution: Right-click the project in Solution Explorer, select properties, and change the FrameWork version of the FrameWork to. net4.
