阅读更多关于 ASP.NET MVC5/IIS Express unable to debug - Code Not Running

问题 I start a VS2013 VB.Net MVC5 Web Application, set a breakpoint in HomeController About method and run "Start Debugging", navigate to About page and receive the message "Code not running - The current Thread is not currently running or the call stack could not be obtained" preventing any debugging. If I set a breakpoint in Global.asax Application_Start, the breakpoint works fine. Changing the "Enable Edit & Continue" makes no difference. Anyone have any ideas what is happening? Update : My

Now anytime I try and debug it says no source available on all BCL stuff For example, on a debug.print I get that message with Locating source for \'f:\\dd\\ndp\\fx\\src\\CompMod\\System\\Diagnostics\\Debug.cs\'.

问题 I have a solution in Visual Studio 2008 which has multiple projects. One of the projects is a WCF project.

Can I find out the return value before returning while debugging in Visual Studio?

阅读更多关于 Can I find out the return value before returning while debugging in Visual Studio?

Take the following function: DataTable go() { return someTableAdapter.getSomeData(); } When I set a breakpoint in this function, is there a possibility to inspect the returned value? go() is directly coupled to a datagrid in an .aspx page. The only way to inspect the returned datatable is to use a temporary variable. However, that's a bit inconvenient. Isn't there another way? Marc Gravell Not that I know of. Note that if you do add a variable, it will get removed by the compiler in release builds anyway... Update: This functionality has been added to VS2013 . You can see the return values in
