                                  • [DevExpress Support Team: CLONED FROM T317724: Do I already use CodeRush for Roslyn?]
                                    Hi there
                                    I just decided to uninstall CodeRush for Roslyn because working with it has too many unacceptable side-effects.
                                    The most important is the one, that if you have a Region containing a huge amount of constants and you would like to delete then these constants, VS freezes while increasing the amount of Memory used by 10 MB/s.
                                    The only solution is to uninstall CodeRush for Roslyn and then all works as expected.
                                    The attachment contains the file with the Region named "DataSet Constants"
                                    I don't know whether it depends on the whole solution structure but maybe you can reproduce this behavior on your side by trying to delete this Region.
                                    Any Feedback would greatly appreciated.
                                    Best regards,from Switzerland,
                                    Alex

                                  Hi Pavel
                                  This fix doesn't seem to fix anything.
                                  The behavior is the same as before.
                                  Attached you will find the latest logfile.
                                  Best regards,

                                   Hello Alex,
                                  I am concerned to hear that the hotfix does not help you. I was able to reproduce this issue on my side before, but cannot reproduce any freezing after I have installed the hotfix.
                                  I have attached a screencast that illustrates my attempts. It would be a great help for us if you provide us with a screencast illustrating the problem in action. For instance, you can capture it using a free Jing tool from TechSmith.

                                  We are looking forward to your response.

                                  Hi Pavel
                                  Thanks for the update.
                                  VS doesn't crash but it still freezes.
                                  I just try to delete the mentioned constants section. The waitcursor appears and after 2 Minutes of waiting I kill the process by using the TaskManager.
                                  There's no activitylog entry written for this.
                                  Are you interested in looking on my Screen by using TeamViewer?
                                  Best regards,
                                  Alex

                                  Just restarted vs and received the attached ActivityLog

                                • Pavel A (DevExpress) 01.28.2016

                                   Thank you for the clarification and providing additional information, Alex.
                                  It is a great option to connect to your machine by using TeamViewer, but we need to do some preparation to make our session more productive.

                                  First, please clarify if you are using CodeRush for Roslyn and CodeRush Classic together? If so, unload CodeRush Classic (by clicking DevExpress -> CodeRush -> Unload ) and try to reproduce the freezing without it.

                                  Second, are you observing full freezing of Visual Studio or just a slowdown? If it is full freezing, it can be related with threads' deadlock. In this case, we would need the call stacks from you received at the moment of the freezing. To capture them, follow the steps described in the Collecting a call stack to track down the cause of VS crash or freeze issues article.

                                  On the other hand, if this issue is a slowdown in the VS operation, we need to collect information about its performance. The best way to do it is to use the PerfView tool from Microsoft. Please install it and perform the steps shown in the attached video. Or, if you have any difficulties with it, we will connect to you by using TeamViewer and will perform these steps on your side.

                                  We greatly appreciate your cooperation.
