  1. Set COMPLUS_FORCEENC to 1 for any process launched using "Start without debuggging"

    I assume that the fact that you spent time on engineering the 'Edit and continue on attach' feature announced here:

    https://blogs.msdn.microsoft.com/visualstudioalm/2015/04/29/net-enc-support-for-lambdas-and-other-improvements-in-visual-studio-2015/

    means that you recognise that there are circumstances where developers don't want to launch their process under the debugger even when they are planning to use it later. This is great; so thanks! Unfortunately it's a little bit awkward to use at the minute but I think this could be addressed with a minor improvement in Visual Studio...

    The ideal thing would be to simply make sure that COMPLUS_FORCEENC=1 is added to the environment of any process launched using…

    • Allow viewing async tasks in ASP.NET applications

      Currently, it doesn't seem possible to get a view of async tasks in the Tasks window when debugging an ASP.NET application. It seems that asynchronous (async/await) coding is being pushed by Microsoft and is becoming a generally accepted Good Thing for web applications in many languages, but debugging asynchronous applications with no visibility of outstanding or current tasks is very difficult.

      The Tasks debugging window only seems to work in a very simple scenario: when running an application (such as a console app) under the debugger via F5. Attaching to an existing process or launching an ASP.NET application running under…

        Thank you for using Visual Studio and for your commitment to improving it. We are currently evaluating whether we will be able to provide the ability to show outstanding tasks in the Tasks window after attaching to a running application as suggested. We will be providing an update soon.

      • Allow the debugger to stop on user/handled and thrown exceptions in MY code but NOT in third party libraries

        In the exceptions window I can set the debugger to stop when exceptions are thrown, even if they're inside a try/catch block, but I only usually care about doing this for my code. Various third party libraries throw exceptions internally for whatever reason and I generally don't care about those, as those libraries will generally allow the exception to bubble up if it's something I care about.

        I'd love it if there was an option to select exceptions that are "thrown in my code" or something to that effect.

        • Add horizontal scrolling in "Timeline details" pane of Application Timeline tool

          There needs to be a way to scroll horizontally in the "Timeline details" pane of the Application Timeline tool. When the logical tree is very deep, and the monitor size/resolution is limited (such as when remote desktopping on a laptop) it becomes impossible to see the names of the elements in the expanded logical tree of the Layout event.

          As a current workaround to this limitation, one can hobble through "blindly" and expand the tree using the arrow keys, while simultaneously looking at the complete logical tree in another tool, such as Snoop, and correlating it back to what is…

          • Allow per-project natstepfilter files

            VS 2015 added the ability to add natvis files to a project. This is great because it allows the natvis files to live near the code and automatically get imported any time the project was included.

            It would be great if the natstepfilter files were handled the same way and automatically imported as part of the project.

            With the current setup, debugging files (natvis and natstepfilter) are separated since only the natvis files can be part of the project. It would be helpful to be able to have them back in one place again.

            • Unit test configuration file .runsettings support system environment variables

              When we configure .runsettings, we have to specify the hard coded value, such as


              x64
              C:\TEMP\TestResults

              But if I use $(platform), or $(ProjectDir) variables which is defined in my system path or visual studio, it can't work.

              So, can unit test configuration file .runsettings support system environment variables?

              • Support multiple "Start Debugging" toolbar buttons that launch the app with different command line parameters

                When developing a Windows console application (in either C# or C++), my team and I frequently have to test the application with 2 or 3 different sets of command line parameters. It is very annoying to have to go to the properties window and change the command line parameters for debugging (usually it involves copying a long string from somewhere) and then clicking "Start Debugging". It would be much more efficient to associate a particular command line with a button on the taskbar and then have multiple buttons to click. This would rapidly speed up development for us.

                • option to enable std debug ("Just my code" off?)

                  João Vitor Wed, Dec 3 2014 11:39 PM

                  Paranoid people should have a option to enable std debug ("Just my code" off?).

                  I think Visual Studio should not debug std by default, it just gets in the way of debugging your logic.

                  • Don't save performance passes (.psess) in solution file (.sln).

                    There are some stuff that gets changed in the solution file if you've done a profiling session (memory or performance, doesn't matter). This is very annoying when using version control.

                    • New debugging feature: debug shunts

                      I sometimes find myself running code in a testing configuration where certain parts of the code can't be run, or certain variables need values assigned. Currently, I set a breakpoint at the start of the code that needs to be skipped, or at the point where variables need to be set up, and then I use 'Set Next Statement' and assignments in the Watch pane to set things up.

                      This works fine, except that if I need to do multiple test runs, I have to repeat these steps *every single time*. For that reason, I'd like to propose a new…

                      • automatically track down memory leaks at the end of the application

                        Vertex

                        it would be nice to automatically track down memory leaks at the end of the application (like in the output window of my native MFC application). Someone can set a breakpoint manually at the "end of an application" and when hit, take a snapshot. But an automatic (with disable option) snapshot at the end of the application would be nice. The question arises, where is the correct end at which I want to have my snapshot. In a MFC/CRT application I would trigger the last snapshot at the time the MFC/CRT memory leak thing tracks the leaks down. I…

                              For example bug in often called function F2(), that called indirectly from function F1(). I can't set breakpoint directly to F2() because it's called very often before F1(). So I need set breakpoint to F1() and then when it triggers to F2()

                              • Save and Load set of selected exceptions

                                When debugging several applications I find myself often to enable breaking on a specific set of exceptions in one application and another set of exceptions in another application. Since this is a rather work-intensive process it would be nice to save and load those selected exceptions.
                                Another helpful addition would be to support the <F3> key as an alternative to the "Find Next" button.

                                • Diagnostic Tools support for Windows Store projects that are running on a Windows Phone.

                                  I would very much like the return of the support for Diagnostic Tools in Universal Windows projects running on a Windows Phone (ARM)
                                  This feature worked on Windows Apps 8 but according to the link There is no longer this support and do not know why.

                                  • Make the QuickWatch window non-modal

                                    Currently QuickWatch opens in a modal dialog which must be closed in order to interact with the code editor.

                                    This is annoying when you have a state in your QuickWatch window that takes time to reproduce, as you have to reopen the window after doing simple debugging tasks such as stepping through code etc.

                                    • Allow Excel export for Diagnostic Tools Events

                                      Allow Excel export by Ctrl+A, Ctrl+C, Ctrl+V or some other method. Would be extremely useful for further analysis and readability.

                                      • Make the debugging Visualizers non-modal windows

                                        Quite often when debugging, I want to see the results of a dataset while stepping through code. Unfortunately the visualizer window is modal, so that is not possible. I currently get around it by taking a screenshot of the visualizer window, which is less than ideal.
