Visual Studio 2015 keeps switching startup project
Visual Studio-2015ProjectStartupVisual Studio-2015 Problem Overview
When changing startup project for the solution from project A (initial startup) to project B (newly added project) the change of the startup project does not appear to be saved.
When running F5 VS always change back to original setting of project A.
I have checked the settings and also options build and run (for new solutions use the currently selected project as startup project) is not checked.
I have tried to delete the .suo file and so far no luck so any other ideas whats going on ?
Visual Studio-2015 Solutions
Solution 1 - Visual Studio-2015
Resharper , run configuration was the culprit in this case. The change was caused by that
Solution 2 - Visual Studio-2015
ReSharper -> Tools -> Run Configurations...
I like to delete all the run configurations I find in that menu.
Solution 3 - Visual Studio-2015
I had this experience after using the Resharper command 'Create Run Configuration' on a unit-test project. Thereafter, using F5 would always try (unsuccessfully) to run that project, and switch my default. I worked around it by running 'Create Run Configuration' again on the project I want to run.
