Edit: There are other SO answers that say you simply can't do this. One is from back in 2010. That's simply not true. I've been able to run VS as non-admin and debug my web sites. It's only after upgrading to Win 10 that I've had this problem. So the answer from back in 2010, that you can't do it, is simply wrong.
When running my web app within Visual Studio, I'm getting this error:
There are about a thousand suggestions online, and none have worked for me. Well, running VS as administrator works, but I don't want to have to do that. I'd like to know what the problem is, and if there is a solution other than running VS as admin.
