Hi,
I have upgraded my project from .net framework 1.1 and infragistics 5.3 to .net framework 3.5 and infragistics 11.1 clr 3.5.
I have up upgraded using version utility, changed all references and toolbox to clr3x.
When I run the project I am getting this error
The following information is part of the event: System.NullReferenceException: Object reference not set to an instance of an object.

Hi orkay,
It has been some time since your post, however in case you still need assistance I would be glad to help.
Please note that between versions 5 and11.1 of .NetAdvantage, some breaking changes might have occurred which could be the root of your issues in this scenario. I suggest that you take a look at our documentation in order to check whether some of these known changes may be relevant to your project:

Feel free to contact me if you have any questions.
