Mono Migration Assistant
Jonathan Pobst released the Mono Migration Analysis tool as part of the Mono 1.2 launch, and we were able to get a tremendous amount of feedback on what features people depended on.
Both features that were known to have limitations in Mono (they are called "MonoTODOs") as well as APIs that we have not yet implemented.
This release addresses many of the issues that were reported: implementation of many APIs that developers needed, removal of incorrect MonoTODOs that we had accumulated over the years and clarifications to many of the MonoTODOs to actually describe the limitations found.
Specifically, this release:
- 496 new methods implemented.
- 212 removed bogus TODOs.
- 65 removed NotImplementExceptions.
New in Mono 1.2.2
This release contains many bug fixes to the C# compiler, Windows.Forms and ASP.NET. Developers and users are encouraged to upgrade to this release.
This release also includes a critical fixe to the runtime startup. Heavily multi-threaded applications would have crashed otherwise.
A new version of Moma, available with this release has been prepared: it has been updated to use the 1.2.2 API, contains an updating mechanism (so we can update the APIs without releasing new Momas) and we optionally allow developers to enter information that you want to send to the Mono team [Jonathan Pobst].
Jonathan Pobst implemented many new classes from Windows.Forms 2.x. Mono now supports ContextMenuStrips, ToolStripContainers, ToolStripDropDownButtons, ToolStripManager, and ToolStripSplitButtons.
Many updates and bug fixes, specially to MDI code.
We found another series of problems with anonymous methods. Martin fixed all the known problems.
We strongly encourage developers to upgrade to this version of Mono and the C# compiler as the code generated between 1.1.18 and 1.2.1 would not have the proper activation semantics for variables captured by anonymous methods [Martin Baulig].
In addition, the merging of the MCS and GMCS compilers continued. The tokenizer is now shared, which only leaves the parser and the generics support as a difference between the two compilers [Marek Safar].
We continue to improve the ASP.NET 2.x implementation.
Support for registering controls from within Web.config (if that went into the release), several improvements to handling of App_Code and fixed support for in Web.config [Marek]
Our internal cairo implementation has been upgraded to version 1.2.6.
Improvements to 2.0 classes dealing with X.509 certificates [Sebastien].
mkbundle now can generate code that can be embedded into an application (in addition to generating standalone applications) [Joshua Tauberer].
Under the 2.0 profile, we now do lazy initialization of the Console, so the new code is only activated if the user actually needs some of the new features, reducing memory consumption, but also keeping the semantics of 2.0 compiled applications inline with Unix unless new features are requested (Gonzalo).
Many improvements and bug fixes to the VB runtime, and it is now running IBuySpy, DevZone (Based on DotNetNuke)
The ASP.NET sites were tested with Grasshopper, as Mono does not yet have a complete VB compiler available to compile Visual Basic applications on the server.
