Answer 1

You need to alter it slightly to not wait on the web server to die, like this

<Exec Command='start /B $(WebServer) /port:3811 /path:$(Path)' />   

I'm not sure exactly why you're starting a Web Server as part of the build, but the default behavior is going to be MSBuild waiting for the WebDev.WebServer.exe to exit/close. You can read more about how START works here and here. It basically kicks it off as a separate process, not one it waits on.

Answer 2

becouse of Invalid switch i try now like

<Exec Command='start /B $(WebServer) "/"port:3811 "/"path:$(Path)' /> 

but i get The system cannot find the file /port:3811. If i run without start /B works but never end again
