Debug in version 5.1. Finally it works!

Hi Guys,

Quick post today.
It seems that application debugging in version 5+ is not an easy task.

What to do to achieve it:

1. Make sure Application pool is in Classic mode, not Managed Pipeline Mode.

2. Make sure you added below highlighted in Red setting in web.config:

<compilation debug="True" defaultLanguage="c#" numRecompilesBeforeAppRestart="9999" targetFramework="4.5.1">

3. Also add this key to web.config into appsettings section:

<add key="UseRuntimeCompilation" value="False" /> 

4. Make sure you have installed Visual Studio 2012, .NET 4.5.1, and .NET 4.5.1 Multi Targeting Pack

5. No need to install Acumatica Framework :)

6. Create New Extension Library (Dummy One) under Customization Project Editor. This will create a solution link for Visual Studio.

7. Open Visual Studio. Navigate to App_Code/Caches.

Here we are :) Attach to the process and Enjoy.

All the best,



  1. That's a great news.. i'm gonna try it.. excellent post

  2. I put breakpoint in some liecode and then after I try to attach process w3wmp.exe, and then I go to the site. After I click on button of the site, visual studio doesn't run debug in step by step, I mean I cannot run debug step by step...
