Learn to Use a Label Creator Add-in Extension in Dynamics 365 for Finance & Operations

by | Updated April 3, 2018 | Development, Dynamics 365 for Finance and Operations

Creating labels has always been considered a chore by developers, and the task hasn’t really gotten any easier with Dynamics 365. Wouldn’t it be nice if you could type your value into the property and let Visual Studio move it to a label file? Luckily, we can. I’ll show you how to use the label creator Add-in extension in Dynamics 365 for Finance & Operations.

Start by creating a new Dynamics 365 Developer Tools Add-in project.

Create new Dynamics 365 Developer Tools Addin project

This will create a new class library project that contains two source files. The first, DesignerContextMenuAddIn.cs, contains boilerplate code for creating a designer add-in. The second, MainMenuAddIn.cs, contains a menu add-in.

Label Creator Addin Extension

The first thing we will need to do is to add a few references to our project:

  • C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv\PublicAssemblies\
    • EnvDTE.dll
    • EnvDTE80.dll
  • C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\5hutepyf.xp2\
    (Your folder may vary slightly)

    • Microsoft.Dynamics.Framework.Tools.LabelEditor.dll
    • Microsoft.Dynamics.Framework.Tools.ProjectSystem.dll
    • Microsoft.Dynamics.Framework.Tools.ProjectSupport.dll
  • C:\AOSService\PackagesLocalDirectory\bin\
    • Microsoft.Dynamics.AX.Metadata.dll
    • Microsoft.Dynamics.Framework.Tools.AutomationObjects.dll

Our designer’s context menu is controlled by the DesignerMenuExportMetadata attribute on the class. You can see in the screenshot that by default our add-in will appear in both the Form and Table designers.

The OnClick method is called when the user clicks on our menu. We will modify this method to convert the text contained in the Label property to an actual label. To do this, create regular expression to distinguish between a label identifier and a normal string.

Lastly, open the resource file and change the DesignerAddinCaption. This value will appear in the context menu item.


To test your add-in, press F5 and Visual Studio will build your project and copy the dll to the appropriate folder. On my computer, the add-in folder is at C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\5hutepyf.xp2\AddinExtensions\.

Create a Dynamics 365 Unified Operations project.

    Hello Mark,

    I have an error while trying to add the source code into the relevant class. The compiler error is indicating that it cannot find a definition for DesignerContextMenuAddIn.Context. A google search of DesignerContextMenuAddIn.Context did not help out neither. Could you point me, or anyone else trying this out to work?

    Thanks in advance.

    Hello Fayt,

    I’ve spoken with Mark on this and he noticed that there are two static members missing from the class. They are listed below.

    static DTE2 MyDte => CoreUtility.ServiceProvider.GetService(typeof(DTE)) as DTE2;
    static VSApplicationContext Context => new VSApplicationContext(MyDte.DTE);

    Hi Mark,

    Brilliant stuff, massive thank you for writing about it! The label editor is a massive pain point for me, indeed!
    Tried following your footsteps, but got some issues.

    When created the blank project, it immediately have had reference issues (6-7 references were not found).
    I managed to find most, but Microsoft.Dynamics.Framework.Tools.Extensibility.dll

    Any chance where can I find it?

    I’m working on an upgraded 7.2 PU12 (to PU15) OneBox dev environment.

    Many thanks in advance,

    Kind regards,

    Hello Attila,

    I spoke with Mark and the following was his response:

    “You will have to search your hard drive for the location of the assembly. I’m now on 8.0, and mine was found in the add-in folder, C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\agk3do44.e2i\Microsoft.Dynamics.Framework.Tools.Extensibility.dll.”
