在调试模式下在解决方案中启动另一个项目

Question

I am working on two processes that interact with each other via named pipes. Process#1 is running in debug mode and it starts Process#2 with Process.Start("process name") I want to run this process#2 on debug mode also, using breakpoints. How can I do this?

I have tried using "Attach to Process" tool in Visual Studio 2008 but it's not very practical when you are in the development process. You need to start Process#2 in order to attach to it. I want Process#2 to be started directly in debug mode.

Answer 1

Put this line in the Main() method of the 2nd project:

  System.Diagnostics.Debugger.Launch();

That brings up the just-in-time debugger prompt as soon as the 2nd process starts running. You can pick either a new or an existing instance of visual studio to debug it. Use Debug + Step Out to get back into managed code.

Answer 2

如果对此项目有相同的解决方案，则可以在解决方案属性中使用多个启动（解决方案属性->启动项目）

Answer 3

Go to solution properties in VS. Opt for multiple startup project. Unless your requirement insist opening of second app from first, this should work fine.
