Release notes for MonoDevelop 2.0 Beta 1

MonoDevelop 2.0 Beta 1 (1.9.2) has been released. MonoDevelop is a GNOME IDE primarily designed for C# and other .NET languages.

This is the third release of a series of releases that will lead to MonoDevelop 2.0, hopefully around the end of March. This release contains lots of new features and improvements. Read below.

Installing MonoDevelop

Compiling the following order will yield the most favorable response.

  • Gtk# 2.8.0
  • Mono.Addins 0.3.1
  • Monodoc 1.0
  • MonoDevelop 2.0 Beta 1 Source

It is highly recommended to use Gtk# 2.8.4 or later, since it includes important memory use and performance improvements.

You can download MonoDevelop 2.0 Beta 1 source from here. The Mono download site contains packages for everything for many popular distros.

This release of MonoDevelop needs at least Mono 2.0 to run.

Installing Add-ins

There are some add-ins which are distributed as separate packages. Those packages are:

  • monodevelop-boo: Boo language binding.
  • monodevelop-java: Java language binding (with IKVM).
  • monodevelop-database: database management add-in.
  • monodevelop-vala: Vala language add-in.
  • monodevelop-debugger-mdb: Mono debugger support.
  • monodevelop-debugger-gdb: Native debugger support with GDB.

Other add-ins are available using the MonoDevelop Add-in Manager (in the Tools menu, click on ‘Add-in Manager’ and then on ‘Install Add-ins’).

New Features and Improvements

Per-project/solution Policies

Many of the settings that were previously only available in the user’s global preferences can now be set per-solution and per-project. Those settings are grouped in what we call policies.

Policies include:

  • Text style: tabs to spaces, tab width, etc.
  • Standard header
  • Default namespaces for projects’ directories
  • Resource naming styles
  • Commit message formatting
  • ChangeLog location and formatting

Policies can be applied to solutions, and can be overridden on child projects or solution folders.

The default policies for new solutions, or solutions without policies applied, can be edited in the Edit->Default Policies dialog.

Project System

This release includes full support for multiple target frameworks. The .NET 3.0 and 3.5 target frameworks are now explicitly supported. MonoDevelop will now detect inconsistencies in project references. For example, a project targeting the 2.0 framework won’t be able to reference projects targeting 3.0 or 3.5.

Compatibility with the MSBuild project format has also been improved. (Lluis Sanchez)

Web Development

ASP.NET code completion better supports child controls and custom controls. Tags in standalone HTML documents are now autocompleted. (Michael Hutchinson)

Source Code Editing

Source Code Editor

The source editor now has an indication in the margin of lines that are dirty or changed.


The performance has also been improved. (Mike Krüger)

C# Code Completion Improvements

There have been many fixes and improvements to C# code completion. Code completion is more reliable and works in more contexts. Autocompletion of constrained generic parameters is now supported. (Mike Krüger, Lluis Sanchez)

vi Modes Support

Several missing commands have been implemented, and mouse selection is handled better. (Michael Hutchinson, Levi Bard)

Gtk# Designer

Better support for moving files. When moving a window or widget implementation from one project to another project, the design will also be automatically moved. (Mike Kestner)

Go to File Dialog

The Go to File/Type dialog has been greatly improved. It now supports acronym matching. The filtering algorithm tries to find the best match, not only by searching substrings, but also by splitting the search string in several parts and trying to match them through all the words that compose the string being checked. (Lluis Sanchez)

Integrated Debugger

The integrated debugger keeps improving. The new Exception Filter dialog allows selecting a set of exceptions, and the debugger will stop when any of those exceptions is thrown.

The new Expression Evaluation window allows to quickly evaluate an expression while the debugger is stopped.

The expression evaluation engine now supports asynchronous evaluation, so execution of methods or properties won't freeze the IDE anymore.

(Lluis Sanchez)

Vala Support

Added support for valac --thread flag. Errors generated by gcc are now properly shown. (Levi Bard)

Other Improvements

  • Improved key binding customization. The stock key binding schemes have been cleaned and corrected. The key binding customization panel now detects conflicts. (Lluis Sanchez)
  • Find in files: matches are now highlighted in the results list. (Lluis Sanchez)
  • Shortcuts for switching pads. It is now possible to define shortcuts for activating pads. (Lluis Sanchez)
  • Assembly browser: Navigating through definitions by clicking on identifiers is now supported. (Mike Krüger)

To all of our wonderful testers, who had the patience to use unstable versions of MonoDevelop for everyday use, and managed to post nice bug reports.

To Mike Krüger and the rest of the AlphaSierraPapa team for giving us a great codebase to start from, and continuing improvements.

To Pedro Abelleira, Todd Berman, John Luke, and other early contributors who started this adventure 5 years ago, and who believed in the feasibility of the project.

To all of the active and not so active (we miss you!) MonoDevelop developers.
