in Mono 3.0.2
We are now on a cadence to deliver new Mono features and updates
on a regular basis. A month after our last release we are now
bringing some 363 commits, with 3055 files changed, 171240
insertions(+), 179104 deletions(-) Major Features
'Reactive Extensions': Mono now bundles the open sourced Microsoft's
Reactive Extensions
F# 3.0: We have updated the bundled F# compiler on OSX to version
3.0 (tag 3.0.22 from the open source fsharp repository).
SGen Garbage Collector: new lazy sweep strategy in Mono's new GC
that reduces the GC times for major collections significantly. We
have also tuned and improved the collector.
System.Json: We reverted System.Json to Mono's version, as it was
lighter and tolerates more input than Microsoft's one. We ship
System.Json.Microsoft as well for users that want to use the
Microsoft stack.
Runtime: Many improvements to Mono, better x86 and ARM support
across the board.
NTLM: Large upgrade to our NTLM stack.
clang: Mono now builds with Clang.

New in Mono 3.0 Major Highlights C# Compiler
Mono now has a complete C# 5.0 compiler with asynchronous programming
support.
Our C# compiler has now completed its migration from using
System.Reflection.Emit as its code generation backend to use the
IKVM.Reflection API. This functionality was previewed in Mono 2.10
and is now the default. With this functionality, developers can
use any mscorlib that they want (for example the MicroFramework
one, or a custom one) without having to build a custom compiler.
We were able to eliminate the multiple executables for the compiler,
and unify all the compilers into one as well as reducing our build
times significantly.
gmcs, dmcs and smcs are now merely aliases to call the mcs compiler
with the proper -sdk flag. Tool/Library Purpose Profile
New Backend 2.10 Backend gmcs C# Compiler 2.0

4.5 System.Reflection 4.0 Mono.CSharp C# Compiler as a Service
2.0, 2.1 and 4.0. System.Reflection 4.0 System.Reflection
System.Reflection is still used as a backend for the compiler as
a service and the C# interactive shell. Evaluation can now Compile
Types
The Evaluator.Eval () API is no longer limited to expressions and
statements, you can now pass entire namespace, class, interface,
struct definitions as a string and have the result get compiled.
This extends to the csharp command:
csharp> class X { public int a; } csharp> var t = new X () { a =
1 }; csharp> print (t.a); 1 csharp>
Instance API
The compiler as a service exposed by the Mono.CSharp library is no
longer limited to be a global compiler, now you can instantiate
multiple scopes for the compiler, each having its own set of
localized types and global variables.
For example, the following sample assigns a string in one context
and an int in another one:
using System; using Mono.CSharp;
class MyWorld {
public Evaluator Evaluator;
public MyWorld (string [] args) {
var r = new Report (new ConsoleReportPrinter ());
var cmd = new CommandLineParser (r);
var settings = cmd.ParseArguments (args); if (settings
== null || r.Errors > 0)
Environment.Exit (1);
Evaluator = new Evaluator (settings, r); } }
class X {
static int Main (string [] args) {
var first = new MyWorld (args); var second = new
MyWorld (args);
first.Evaluator.Run ("var Demo = \"hello, world\";");
second.Evaluator.Run ("var Demo = 1;"); first.Evaluator.Run
("print (Demo);"); second.Evaluator.Run ("print
(Demo);"); return 0; } }
C# Interactive Shell
New convenience function print, can be used instead of Console.WriteLine
Additionally, the C# interactive shell will by default use a terse
syntax that does not require a semicolon at the end of an expression,
for example:
csharp> 1 + 2 3 csharp>
4.5 Profile
The 4.5 Profile is a strict superset of the 4.0 API and is now the
default profile.
Because 4.5 API is a strict superset of 4.0 API they both share
the same assembly version number, so we actually install the 4.5
library into the GAC.
Some of the changes in the 4.5 API family include:
New Async methods WinRT compatibility API Newly introduced
assemblies (System.Net.Http, System.Threading.Tasks.Dataflow)
New Microsoft Open Source Stacks
We now include the following assemblies as part of Mono from
Microsoft's ASP.NET WebStack:
System.Net.Http.Formatting.dll System.Web.Http.dll System.Web.Razor.dll
System.Web.WebPages.Deployment.dll System.Web.WebPages.Razor.dll
System.Web.WebPages.dll System.Web.Mvc.dll System.Json.dll
(Previously available in Mono, but now replaced with Microsoft's
implementation)
We also bundle the recently open sourced Entity Framework and
EntityFramework.dll
Garbage Collector
SGen now has a new task management system that allows it to easily
scale new GC-related tasks across multiple CPUs if available:
SGen on SMP systems is able to distribute more work across the
worker threads. Previously only the mark phase was distributed.
SGen is now able to perform parallel collection in the nursery.
SGen has been ported to Win32 SGen has been ported to the MIPS
platform Precise stack scanning has been improved considerably,
and it is now supported on x86 and ARM. On OSX, SGen now uses
Mach APIs directly to speedup some tasks in the garbage collector.
Runtime Optimizations
Implemented fast version of ThreadLocal<T> (it is now a low-level
intrinstic operation)
List<T> optimizations
Support for new attributes to force inlining.
Major change in Mono to support the full table of Unicode surrogate
characters. This code was written by Damien Diederen and David
Mitchell from Logos software.
Runtime supports deferred attaching to the process (when using
suspend=n,server=y the runtime collects metadata until a debugger
is attached).
Implement tail call optimizations on PowerPC for F# (Bug #664631)
New profiler that can be used with Intel's VTune Amplifier Profiler.
Support for System.Net.NetworkInformation.NetworkChanged events on
Linux.
New tool: crlupdate this is the Mono Certficate Revocation List
Downloader and Updater and can be used to download of new, or update
of existing, Certficate Revocation List (CRL) associated with the
certificates present in the user (default) or machine stores. The
CRL present in the stores are used to determine the validity of
unexpired, trusted X.509 certificates. ASP.NET
Bring the error page to the new millenium. CodeContracts
Alexander Chebaturkin has implemented initial version of static
Code Contract analyser as part of SoC 2011. Smaller Updates
Partial support for Portable Class Libraries (details)
Updated Unicode tables, fixes long-standing 480178 MacOS X
We continue to expand significantly our support for MacOS X and
iOS.
Mono can now be compiled by users as a 64-bit binary. Mono still
ships as a 32-bit binary, as most libraries that exist today for
Mono run only in 32 bits.
DriveInfo now returns correct information on OSX. Mono.Data.Sqlite
It is now possible to configure the threading model for SQLite
using the SetConfig method in the SQLiteConnection class.
Supports iOS crypto APIs. C5 Library
We have updated the venerable C5 library to the latest version.
Breaking Changes Since Mono 2.10
In order to be compatible with Microsoft .NET's behavior, exceptions
thrown in object finalizers now cause a full runtime abort. This
behavior was already present for thread pool threads, but hadn't
been enabled for the finalizer thread yet.
Generally, one should avoid exceptions in finalizers entirely. If
you must use them, catch them so that they do not terminate the
application. GDB
GDB support has been extended with a new gdb hook that is aware
of the SGenGC internals. Added pretty printers for more runtime
data structures like MonoVTable to the mono gdb mode.
MIPS port
The MIPS port is now complete, it can do a full bootstrap, and run
the runtime/corlib test suites. Soft Debugger
Single stepping is now implemented using breakpoints in most
cases, speeding it up considerably. Calls to
System.Diagnostics.Debugger:Log()/Break () are now routed to
the debugger using new UserLog/UserBreak event types. S390x
is now supported (Neale Ferguson). MIPS is now supported.
Added new methods to Mono.Debugger.Soft and the runtime to
decrease the amount of packets transmitted between the debugger
and the debuggee. This significantly improves performance over
high latency connections like USB. Many bug fixes.
Static Compiler (AOT)
Made changes to some AOT data structures to reduce their size,
especially when using generics. This reduces the size of an mscorlib
AOT image by about 1-2%.
Many changes to the class libraries allow more core Generics code
to run on systems that do not support JIT compilation.
2.10.9
Fix a libgdiplus issue that had forced linking against Apple's X11 stack for text rendering.
Fix issue where a native crash causes MonoDevelop to hang and neither Force Quit nor kill -9 would terminate it (Xamarin #2548).
