My comments here are the latest focussing on your orignal issue. Either you created a problem with deployment or within Visual Studio. I have listed two common remedies. Regards, Frank
I have done all that multiple times (del .vs/obj/bin) restart VS/clean/rebuild.. I removed the buttons that were not firing and still wisej.ex is not loading.
Error 500 doesn’t depend on a button added or anything else in wisej. It’s most likely the wrong configuration in web.config. You may have mixed the aspnet core handler with the aspnet handler.
I compared the web.debug.config files between the one that works and the one that doesn’t. I made the non working one match the working one. IT STILL FAILS.
At this point I’m going have to copy folder by folder to a new project. GRRRR!!!
