I'm getting this error on my build:

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

The way I see, there is something wrong with your roslyn exe.

    The problem with the default VS2015 templates is that the compiler isn't actually copied to the {outdir}_PublishedWebsites\tfr\bin\roslyn\ directory, but rather the {outdir}\roslyn\ directory. This is likely different from your local environment since AppHarbor builds apps using an output directory instead of building the solution "in-place".

    We're working on a way to make the build process work better with the new templates, but right now you could get around it simply by copying the files to the expected directory as a post-build event in your web project file using for instance xcopy.

    I've made a quick sample MVC5 app based on the VS2015 templates where you can see how this is done. You can likely just copy-paste the lines added in this commit in the bottom of your web project file to fix this issue.

    Hope this helps!

    I was able to build the Project, but it entered a infinte loop of build and precompilation, like this:

    We're working on addressing the issue that prevents the builds from completing in some cases. It's intermittent though and will only happen on some builds, so it should be possible to get the deployment through despite this. It also looks like the last built went through OK?

    Hi Rune,

    I've modified my csproj as suggested but it doesn't seem to make any difference.
