I've been looking for a application that I can run on Mac and looked through the jet brains and found rider. Now I created a new file in the .NET core and opened a project. As I saw in your video about Rider that there is a default setting to run the project, however I need to create it all by myself. I've looked through the support on the forums here where I saw a somewhat equal solution but going to my RiderProjects/ClassLibrary1/bin I could not click on the OK button to set the exe path. I am not sure but I also believe you need to fill in a working directory which I do not know if I have.
I'd like to hear from you soon.
