Major Highlights
Mono 2.4.2.1 is a bugfix release for Mono 2.4, which is the foundation for Novell's own long-term support Mono-based product.
In addition to bug fixes, this release includes the following major changes from 2.4.2:
- We now ship Microsoft's ASP.NET MVC stack and ASP.NET MVC applications can run with Mono.
Due to an oversight on Mono 2.4.2, the ASP.NET MVC code was not actually distributed. This oversight has been corrected.
Changes in Mono 2.4.2.1
XSP now has Silverlight mime types registered.
Updated the browser database.
The C# Shell (csharp) will now accept C# scripts specified on the command line, like:
csharp demo.cs
A major bug was fixed for multi-threaded applications using XPath, if you are using XPath in a multithreaded application, we strongly recommend that you upgrade to this version.
