C# - ImageList - how to include it in MainForm resource ???

[CodeExplorer]

So I've added an ImageList to MainForm but unfortunately in compiled exe is not under MainForm resource but as an separated resource called imageListTreeView.ImageStream,
when I try to run the program it complain about resource not being found:
this.imageListTreeView.ImageStream = (ImageListStreamer)componentResourceManager.GetObject("imageListTreeView.ImageStream");

How to fix this problem?

It's hard to guess without having something to look at. Post the project (or DM if it's private)

I resolved my problems.
I simply added again all images and now all works ok, and now ImageList is included in MainForm.
To be frankly I have no idea on why this error came from first place.
