Infragistics license file add itself to project!!?

Question

I have a solution in VB.NET .NET 2

Use Infragistic componets all over the application.

One day decided to add floating toolbar support to our Forms.

Our forms inherit one base form BaseForm. This base form is used in multiple projects in the solution.

So, on the BaseForm was added a UltraToolbarsManager.

Since, a nightmare began: the licenses.licx started to create and add itself to the project on every form opened in designer....

licence.licx contains:

Infragistics.Win.UltraWinToolbars.UltraToolbarsManager, Infragistics2.Win.UltraWinToolbars.v6.3, Version=6.3.20063.53, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb

What to do? Why does this license file appear in the inherited forms?

Answer 1

There's a load of information on the licenses.licx file (and the associated wailing and gnashing of teeth that it often inspires) across the web.

Basically, this file stores the strong name of each assembly that gets loaded in the designer that participates in .NET's component licensing scheme (a simple built-in mechanism that component developers can take advantage of in determining if the developer is using a licensed or demonstration/lite version of their components).

Whenever the designer loads such an assembly, it adds the strong name of the assembly to the project that caused the load. Since you added the toolbar to your base form, opening an inherited form will cause that assembly to load, which adds the line to the file (and creates it if necessary, which is what you're seeing).

Unfortunately, there's not a lot that can be done about the issues it creates. What trouble are you having with it?

Answer 2

The license file only gets created when you add a control to the form. It won't do anything if you open a form with existing Infragistics controls.

If you delete all the lines in the license.licx file after adding the control everything should work.

Our environment has a checked in license.licx file that is empty and we make source control ignore the license file so any changes on a developer machine won't make it into the build machine or anywhere elsewhere.
