This project is read-only.


This is a reflector addin to generate sequence diagram. It is built using the WPF renderer which removes the dependency on Gnuplot and other minor issues.



  1. A version of Reflector is included in the zip file which you can use.
  2. If you would like to use your own version of Reflector then you need to copy the configuration file (Reflector.exe.config) and the Plugin file (Reflector.LiveSequence.dll) in the same directory.
  3. If you already have Reflector.exe.config file then you may need to paste the contents of this file carefully into Reflector.exe.config. In case you don't have Reflector.exe.config file then you can safely use this config file.
  4. Restart reflector to load the updated config file and navigate to any method and right click to select "Sequence Diagram" as shown above.

Try this and for any suggestion/bug report, please drop me a comment.

Great tool. I got it to work in Windows 7, using Reflector The Reflector add-in initially failed to load, until I realized it also depends on LiveSequence.Xps.dll. After copying that DLL into the Reflector folder, it worked perfectly.

I also had NullReferenceExceptions (object not set to an instance of an object) before seeing that I needed to install GNU PlotUtils (thanks ewall). I wish that had been noted in a readme.txt or installation instructions above. After installing GNU PlotUtils, all works well. I am running Reflector version

After installing GNU PlotUtils, you should verify its install path and compare it to the path listed in the .config that needs to be added to your default Reflector.exe.config. This is especially true if you are running an x64 OS - the default install path will be "C:\Program Files (x86)\GnuWin32\bin" whereas the default listed in the .config that comes with this addin is "C:\Program Files\GnuWin32\bin".

It works fine with Reflector v5+... if you have the prerequisites. The errors are because this requires the Win32 port of the GNU PlotUtils ( If you run the setup ( and install to the default directory, you will not need to change the paths in the 'Reflector.exe.config'.

I'd love to see this working with the newest reflector :(

This addin does not work with the latest Reflector. Throws errors when method is selected

Is this working in the new version of .NET Reflector (

Hi! It's great tool, it's nice to have simple and yet fully functional sight to part of the app's functionality. However, it would be nice to add some kind of filter that should allow or disallow drawing of some classes that takes space and they are not always needed. For example the calls to System.Object.ToString() or System,Collection.Generics.List<T>.Add() often take lot of space by drawing the classes or instances (rectangles) and their lifelines, yet they aren't always needed. Maybe to add some inclusion/exclusion attributes that can be added in code or the objects and methods can be just tagged (selected) through context menus in your add-in. Al together - great job!

Question: Before I try to install, does it handle fairly complicated diagrams well? They may get hard to read...

Thanks too for this tool. I got it to work at last by adding a few quotes in PicRenderer.ExecutePlot(), where the argument for Pic2Plot is constructed. Otherwise it struggles with spaces in directory names. Because there is no error checking, it just displays the old .svg instead...

Awesome tool, love it! However, like abaitam i seem to have the issue where the first svg is created and then no matter where i click i end up with the same image - any ideas on what might be causing the issue?

It works fine for me...i am in xp prof...had it work with ever have one problem..if the seq diagram is pretty big with more objects involved, i dont have enough space in the SVG viewer to display that....50% of the diagrams are cut, with lot of space left in the console...Is there any way, we can increase the work space for SVG viewer ?

I didn't check this on Vista so you can try getting the source and compiling on Vista but I don't think that should be a problem. There are cases when it is unable to parse the assembly and therefore unable to render the diagram for the method. To check whether it is setup correctly, you can try loading the log4net.dll in the bin directory.

I am having the same issue as abaitam, the SVG image is always the same regardless of which method I click on. I am using Vista SP1 btw.

I have Adobe SVG Viewer and the plot utility installed and I added appsetting to the reflector config file. However, I always get the same SVG file in reflector. I tried deleting seq.svg but then I get a page not found on the right hand pane. What do I need to make SequenceViz work in reflector.

Does anyone know a software or a tool that allow this requirement, thanks

You have to install the Adobe SVG Viewer add-on in order to get it to work properly

I have the following error when trying to build seq. diagram:
Error occures when add-in tries to process ''file...

I could be wrong, but it seems that the binaries don't work with the new ( version of Reflector.

This i found in Naumans Blog:"MethodViz was a little experiment that I was doing. As you must have read from a comment from Jonathan, it is not trivial to find the full method hierarchy. It found myself like building a JIT compiler myself so I left it there and will not be updating that tool. I am hoping to update SequenceViz to fix any bugs and add any enhancements."
