Since last Friday (04/01/2016) we are using sonarqube in our company. Somehow one of our project\'s issues got all closed (without actually being fixed). And now the project
We encoutered the same problem. Upgrading to sonarqube 5.6 with C# 5.3 plugin did solve our problem.
Thanks to @fluf we found out that the install of visual studio 2015 update 2 caused these problems.
What the root issue is here is still unkown, but its working now.
Workaround: Remove the update 2 installation of visual studio 2015 and replace it with either the update 1 or the one without the updates. Both work well enough to preform the builds en generate the code coverage files in TFS.
Is it possible that the Quality Profile for the project has/was changed?
