New Post: Installing WebAPI on C1 4.2 Update 1

I'm trying to install WebAPI on 4.2 update 1 and I'm getting an error saying that you can't have the App_Code folder when your application is pre-compiled. I'm not able to get back to the frontend or backend of C1 without removing the App_Code folder or the PrecompiledApp.config file, then uninstalling the WebAPI plugin.

So I removed the PrecompiledApp.config file and WebAPI installs successfully. However on the frontend I get a 500 error. No idea how to resolve that.

Thanks for any assistance
