I made a change that undoes the -recursive:\*.cs change that Seo committed earlier. Instead, we continue to parse the \*.csproj files to get the list of files to compile, but conditionally convert \ to / only for Mono (there’s an issue in the C# compiler that prevents relative paths from working correctly if they only contain /'s). Thanks, -John ---

It failed miserably because of case-sensitivity of file names. e.g. error CS2001: Source file `Actions/CallAction.cs’ could not be found Where file is actions/CallAction.cs (directory name in lower case) Compilation failed: 201 error(s), 0 warnings
