By | January 5, 2016

The ILDASM (IL  Disassembler ) is a great tool for those who wants to take an insight look of IL code. This tool is used to view the assembly content for all the code components .  This tools is installed with the your Visual Studio and in a traditional way, can be access from the Visual Studio Command Prompt.  In this post you will learn how you can open the same tool inside Visual Studio by using a shortcut key.

So, in traditional way, To open the ILDASM

  • Open the Visual Studio Command Prompt
  • Run ILDASM Command.
  • Here is a sample screen shots of application opened using ILDASM.

Here is Few Tips that shows use of ILDASM Tool

Here is the problem, whenever you need this tool, ever time you have to open the Visual Studio command prompt and then run it.   What if, if you could do it directly from Visual Studio ? 

Well, follow the below steps to configure your Visual Studio to launch the ILDASM tool.

Navigate to Tools –> External tools



Click on the “Add” button, and then provide Title, Command  ( Which is the physical path of your ILDASM Tool, and then set the Initial Directory as $(TargetDir)



That’s it. You are done ! Click on Apply.

Navigate to Tool menu, and now you should be able to see the “ILDASM (IL Disassembler )” option along with all other external tool.



Click on “ILDASM (IL Disassembler )” to open the Tool directly from the Visual Studio.


isn’t it great ! Let’s me it more easy to access by giving it a shortcut key.

Assigning the Keyboard shortcut for external tools are bit tricky, as they are customizable by end user. So you need to find the position of the external tool in the list of tools that you have and assign the key as appropriate.

In my case, I have it as 4th external tool. So, navigate to Tools –> Options –> Keyboard.

Search for Tools.ExternalCommand4    ( For you it may differ based on the number of tools you have and its index). and then assign key that suits you and is free.

Here I have assigned Ctrl+Alt+I , Ctrl+Alt+L



Now, you should be able to see your external tool with shortcut key and can open the same using keyboard as well.



Hope this helps !
