Mono 1.1.2 is the second release on the development series of Mono and it is not intended to be used for production as it is undergoing internal changes. Those interested in a stable release should use the Mono 1.0.xx series.
The Mono 1.1.xx series will eventually lead to the next stable milestone: Mono 1.2.
The following is a high-level description of the changes in the development release of Mono since the previous development release in September 22nd.
Although this a development version, this release contains mostly bug fixes, speedups and tuning in every subsystem of Mono. In addition to that, some key new changes are:
The C# compiler now supports anonymous methods, you can now write code like this:
Button b = new Button ();
b.Clicked += delegate {
Console.WriteLine ("I got clicked");
}
For more information on anonymous methods, you can read this introduction or read the C# 2.0 specification (Miguel).
Today Mono 1.1.2's C# compiler supports anonymous methods, iterators, partial classes, static classes and inline warning control from the 2.0 specification. Generics are supported as well on the branched `gmcs' compiler (included).
Added support for encoding security permission attributes as part of the ongoing CAS support in Mono (Marek).
Still missing for full 2.0 support: nullable types, namespace alias qualifier, external assembly alias, property accessor accessibility, covariance and contravariance, fixed size buffers and friend assemblies.
Many new errors and warnings reported.
Improved the compiler performance by back porting some improvements from mcs to mbas, compilations that used to take thirty seconds now take one second (Jambunathan).
Anirban continued making improvements to the language support and Jambu redesigned the test suite layout.
We no longer depend on Cairo internals.
Work on the new managed implementation of Windows.Forms continues, we hope that by the next release the new implementation completely replaces the existing version during the build process.
Although there is a lot of progress in this area, Windows.Forms is not yet ready for most people testing it.
Folks interested in helping with the implementation might want to go to the #mono-winforms channel on the irc network at irc.gnome.org.
Chris and Martin worked on the debugger support, the runtime now contains some of the new hooks required by the new debugger. The debugger currently can only be obtained from CVS.
The debugger is available from CVS, in the module `debugger'.
Zoltan has added various Reflection.Emit features from the 2.0 API.
Extensive changes to the Mono runtime for improving our generics support.
The web support has been fine tuned and optimized, the number of requests per second went from 70 to 550.
A big memory leak that would show up on long running servers has been plugged.
The Mono XQuery implementation has moved to a separate assembly Mono.Xml.Ext in lieu and will be available for both the 1.x and 2.x profiles.
Updated the PowerPC, SPARC, AMD64 ports of Mono.
S390 port by Neale got its exception handling and prologs fixed.
Cesar has implemented late binding support for the JScript compiler.
Important: Mono 1.1.2 can not be installed in parallel with Mono 1.0.x series on the same prefix. To work around this issue, you must use a different prefix at configure time, for example:
$ ./configure --prefix=/devel
You can then setup your PATH to include /devel/bin to access the Mono 1.1. Alternatively you can replace your Mono installation with 1.1.2.
Binary Packages:
Pre-compiled packages for SUSE 9, SUSE 9.1, Red Hat 9, SLES 8, Fedora Core 1, Fedora Core 2 and MacOS X are available from our web site from the download section. A Red Carpet Mono channel is also available on these platforms.
Source code:
- Mono Runtime: mono-1.1.2.tar.gz
- Mono C# sources: mcs-1.1.2.tar.gz
- GDI+ library: libgdiplus-1.1.2.tar.gz
Dependencies
If you are installing from source code, there are a few optional dependencies that you will want to consider installing.
icu 2.6.1 or later Optional: for supporting string collation.
Cairo 0.1.23 Required to install libgdiplus.
Quick source code installation:
If we have no packages for your platform, installing from source code is very simple.
mono:
$ tar xzf mono-1.1.2.tar.gz $ cd mono-1.1.2 $ ./configure $ make install
Optional Packages
Libgdiplus is an optional packages, you only need those if you intent to use System.Drawing or Windows.Forms.
libgdiplus:
$ tar xzf libgdiplus-1.1.2.tar.gz $ cd libgdiplus-1.1.2 $ /configure $ make install
