i have downloaded the source for nopCommerce 4.0 and opened the solution in the latest Visual Studio 2017. Build works fine, but when i press F5 nothing happens. Right click on the Nop.Web Project, the submenuitems of debug are disabled. Also in the main menu i cannot start debug. After choosing the run button in the toolbar a message appears that i have no start project. But i have tried several times to select the nop.web project as start project, but everytime i want to start the project i get the same error message.
Somebody knows how to solve this problem?
