Could not load file or assembly ### or one of its dependencies after publish

Question

My problem is that when I ran my project locally it worked just fine. But when I publish to my IIS server I get an error saying.

Could not load file or assembly 'Microsoft.Owin' or one of its dependencies

When I fixed the Microsoft.Owin problem there was a problem with System.Web.Http. Why is it only a problem after I publish?

Answer 1

For some reason that I can't explain (please do if you know why) it worked to use my web.release.config instead of web.debug.config. I copied my entire web.debug.config to web.release.config and it worked.
