I know this question has been posted elsewhere here, but can't find a working solution. I have 2 applications: 1 is an older version of the other and runs a SignalR chat app just fine from VS2015 (using IIS Express), the other app is basically the same except for changes elsewhere (its a shopping cart), but the chat pages, scripts, and references are identical (including the path). Web.config, global.cs, startup are all identical and both run MVC5. The older app uses a standard HTML page and references the SignalR/Hubs just fine (no 404 error) with the following: Here's the agent.html page:

There's more, all of the code works fine on the old version, but not on the new. All the required DLLs are in the BIN folder. The package.config is identical (except an older version of OWIN - which may be suspect). I just don't know where else to look for a difference that would explain why the old version of the Application works and the new one does not (everything loads in the new one, scripts, css, pages, etc. except the dreaded SignalR/Hubs). Is there a setting somewhere that I missed?
