Many .Net developers use to say “if you’re a serious developer, then you MUST Reflector”.

I would like to add another statement: “if you want to have an insight and powerful look at how things works internally, use Reflector Professional”.

Last Wednesday, RedGate released a new version of Reflector. You’re probably going to download it soon or later because your actual version is going to expire. When you’ll download the free version, you’ll automatically get a trial (14 days) of the professional edition. Nice, but what’s so special about this edition ?

Let’s see a demonstration of what can be done using Reflector Pro. The following is not an ad for RedGate, I’m just totally amazed by their new feature

1. Reflector is now integrated into Visual Studio (2005, 2008 and 2010 RC):

2. Select the “Choose Assemblie to Debug…” option to select .Net assemblies for which you don’t have the source code. In this example, I’m using one of the Blend3′s assemblies:

3. Once the process is completed, select the “Explore Decompiled Assemblies” option:

4. Browse to your target assembly and select an interesting type:

5. Put a breakpoint in the code, like you do every day when you debug an app:

6. Run the executable

7. Debug Blend3′s source code ! Use breakpoints, step into methods, inspect variables…

And that’s it. With Reflector Professional, you can:

• Decompile third-party assemblies from within Visual Studio
• Step through decompiled assemblies and use all the debugging techniques you would use on your own code. This is incredibly powerful as we saw by debugging Blend3″s source code !

Reflector Professional is available for about 195$ on RedGate website

I’ve already blogged about R# a couple of times. There is no doubt: it’s a must have for any serious .Net developper. A few weeks ago I learned and setup new shortcuts to improve my navigation skills in Visual Studio.

Here are the results… If I want:

• to find a Type I hit Ctrl+T
• to find a File I hit Ctrl+Shift+T
• to find a Member (in a file) I hit Ctrl+Alt+T (Note: I setup this one on my own using Tools/Options/Keyboard)

A search box opens and I can start searching instantaneously.

Here are the basic scenarios :

• I want to open the ViewModelBase class, I hit Ctrl+T and then VMB (R# is able to search using capital letters)
• I want to go to the OnPropertyChanged, I hit Ctrl+Alt+T and then OPC (same as previous example)
• Finally, to open the file in the Solution Explorer I hit Shift+Alt+L

It’s simply amazing the time we can save using those simple shorcuts. Of course, you need to be quite familiar with your codebase (if you just arrive on a project it will be harder :p)

MIX09 is now over and the good news is that we can watch all sessions that have been recorded online !

I didn’t have time yet to watch all sessions I’m interested in, but I already saw “What”s new in WPF 4″ video (available here).

Here are the important points of this session regarding the future of WPF:

• Lot of new things are coming in WPF4: Text clarity improved, Multi-touch, Windows7 integration, Ribbon control, Focus management improvements, Visual State Manager, Client profile, Themes, Chart controls and a lot of bug fixes…
• WPF4 will come together with .Net4 which brings its own set of cool new stuff: Dynamic Language, MEF, F#, parallel library
• WPF will be the best choise for RAD under Windows7: Multi-touch, Taskbar integration, Ribbon, Common dialogs, File explorer customization…
• Multi-touch support: UIElement changes to manage touch related events, touch support is added for some controls (ScrollViewer)
• New composition API: developers can control graphical elements cached in video memory
• Controls that are currently available in the WPF toolkit will be integrated into the platform (DataGrid, DatePicker…) – moreover an update of the toolkit has just been released
• Developers tools are improved: VS2010 and Blend3 helps the usage of WPF (databinding support…)
• .Net4 will come with a new XAML parser: faster, extensible, public API to manage BAML format
• .Net4 XAML language has new XAML features: support for generics, better references by name

I hope will see a CTP soon so that we’ll start playing with those new features
