A new version of Portable.NET, the Free implementation of Common Language Infrastructure, is finally available. The new version features numerous performance improvements, fixes for WinForms and Xml, and many other changes - read the full list of changes. The new release also brings a new runtime package (at this stage for Windows systems only) - at just under 2MB its goal is to solve the problem of redistributing large runtimes. More details. Full Portable.NET SDK for Windows will be available by the end of the week, so check back for updates :)
