Does appharbor always build solution using 'Release' build config ? Can I make appharbor to build my apps using certain configuration, e.g. 'Release-for-appharbor' ?
AppHarbor always builds your code in Release configuration. You can find additional resources on how AppHarbor recommends you manage environments.
We'd love to have your suggestions on how to improve this, you can add feedback on the feedback forum.
To execute the build process locally in the same fashion as AppHarbor
From the Visual Studio Command Prompt
msbuild solution.sln /p:Configuration=Release /property:OutDir=C:\temp
