In visual studio 2017 community edition,when click the "start"button to start debug,VS will launch rhino to debug,and than I open gh doc related to developing component,and then stop in the break point…this works very well for a long time,but today,when start to debug,in rhino ,i launch gh,the VS show this:

 ![%E5%9B%BE%E7%89%87](https://global.discourse-cdn.com/mcneel/original/3X/c/a/ca4d6adbd37a631a55a49fd7b1e5ee203d541a0c.png)

then i try several time,these problem still exist…  
i copy the code to another computer,it can debug as usually,so I am sure that the problem is inside the Gh,but i dont how to reinstall gh…  
Who know where is the problem in?  
Thank you very much!

i solved the problem by reinstall rhino 5.0.
