VS2010 breakpoints do not work when developing AutoCAD. NET application debugging

vs2010+ AutoCAD 2012 Development debugging process, found that the normal class inside the breakpoint can be traced, may be to create a custom form interface is, Form1.cs code breakpoints are not used. The reason for this is the fiber (Fiber) of AutoCAD. Yes, it's a fiber (Fiber) instead of a thread. There are problems with VS2010 's debugger working with AutoCAD fibers. The solution is to close the AutoCAD fiber. Through the system environment variable Fiberworld to see if the current fiber is open, if it is 1, you can set the system environment variable Nextfiberworld to 0.

Autodesk.AutoCAD.ApplicationServices.Application.SetSystemVariable ("nextfiberworld" 0
