Major Highlights

Mono 2.4.2 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 2.4.0:

  • We now ship Microsoft's ASP.NET MVC stack and ASP.NET MVC applications can run with Mono.
  • xbuild has been updated
  • Removed non-free amqp0-8.xml documentation.

Changes in Mono 2.4

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.

Installing Mono 2.4.2

Binary Packages and Source Code Downloads:

Source code and pre-compiled packages for Linux, Solaris,
MacOS X and Windows is available from our web site from
the Downloads section.

Quick source code installation:

If we have no packages for your platform, installing from
source code is very simple.

Compile libgdiplus to support System.Drawing:

    $ tar xzf libgdiplus-2.4.2.tar.gz
    $ cd libgdiplus-2.4.2
    $ ./configure
    $ make
    $ make install

Then compile Mono itself:

    $ tar xzf mono-2.4.2.tar.gz
    $ cd mono-2.4.2
    $ ./configure
    $ make
    $ make install
