MVC 5.0 500 - Internal server error

Question

I have created an MVC 5 website using Visual Studio 2015 on a Windows Server 2016 Machine.

I build and run the application from VS and it works great.

I published it locally, pointed IIS to the root folder.
The Application Pool is set to .Net CLR Version v4.0.30319.

When I try to access the page on the web, I get a generic error 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.

There is nothing in the IIS logs.

Not sure how to get this error so I can see it...or if it is a more basic issue. Any ideas on the best way to proceed?

To configure within Microsoft Server 2016, do the following:

• Make sure you've installed the feature set for Web Server & Hosting are installed.
• If those are installed, create a directory such as: "C:\Program Files\Sample"
• Publish your application to the directory
• Open Internet Information System
• Disable Default Site
• Create a New Site
• Create a Site Name "Sample" (Take note of the Application Pool Name)
• Now link "C:\Program Files\Sample" in Physical Path
• For now leave the binding defaulted, this will trigger wildcard
• Uncheck Start Website Immediately
• Navigate back to "C:\Program Files\Sample" (Accessible through IIS also)
• Right-Click and go to Permissions
• Choose add new user
• Type in "IIS AppPool\Sample"
• Choose access your application will require.
• Apply those changes, then navigate and start your web-site.

If that doesn't work, you can check the following:
