Depressed, an error is reported between the projects in use. All forms created in the project cannot be used.
The following error is reported: "the type or namespace name 'windows' does not exist in the namespace ...."
Development Environment vs2010 + sql2008
The project has been correctly referenced
The V4 path of system. Windows. forms is correct.
System. drwaing
Using e system. Core ....
Correct reference in code
Using system. Windows. Forms
Have you ever encountered such a situation? Thanks, TMD's inexplicable error.
No changes were found compared to versions on TFs.
There are two winform projects under this solution. This is one of the errors reported. The project after the error cannot create a new form, but the other project can, in addition, I compare the referenced system class libraries one by one :(
I posted a help post on csdn just now, and then I was wondering what I was trying to do, and finally locked it in a reference class library X. sytem, my Kao, is actually a namespace conflict that can also cause such a problem, crazy!
