AppHarbor pre-compilation error

Question

While deploying to AppHarbor, AppHarbor gave me the following compile output:

Microsoft (R) ASP.NET Compilation Tool version 4.0.30319.17929
Utility to precompile an ASP.NET application

This error can be caused by a virtual directory not being configured as an application in IIS.

Website precompilation failed with exit code 1. Precompilation can optionally be disabled in application settings

After searching in the internet, I found a few solutions pointing me over to clean my solution and to configure my app folder as a virtual folder within IIS.

I did the first (and it didn't work) but I have no idea how to do the second from within AppHarbor, any suggestions?

Edit1: Web.Config

Answer 1

You can disable view pre-compilation in application settings. That should steer you clear of the problem.

But I recommend that you check your code because eventually when used, will be thrown this exception again, I recommend some tracers like elmha to help you find the problem in detail. Your webconfig error is steel there
