] > The wix task has an option to run lit.exe rather than light.exe now. The C# compiler uses gmcs on Mono by default now. A new F# compiler task has been added. A new tallow task has been added to ease creation of WiX built installers. The wix task has new nested elements that allow users to send addtional command line arguments to candle and light. The include and exclude arguments to NUnit were broken (they had a leading ","). The /noconfig argument must be used outside of a response file. CSC of .NET 3.5 doesn't support the /incremental argument anymore, only set /incremental+, but never /incremental-. The compilation tasks failed if the source files resided in a directory with spaces in its full path and a response file was used. The NAnt and MSBuild task have new attributes failonerror and errorproperty that allow users to fine-tune Ant's behaviour if either of both signals an error. The NUnit task has a new attribute errorproperty that allows users to set a property if NUnit signals a test failure.
