How insert ImageStream in VS Resources Manager?

Question

I'm working on 4.5 .Net application and need insert ImageStream from old application to new one, ImageStream was saved from ilSpy.

I found way to insert existing ImageStream, you must open .resx file in your new app and add these code.

This works only if res file was created by ResourcesManager ver 4.0.0.0 and above.

<data name="imageList_1.ImageStream" mimetype="application/x-microsoft.net.object.binary.base64">
    <value>..here is resource's body in base64 format..</value>
</data>

Imagestream from subj was created by ResourcesManager 2.0.0.0 (.NET 2.0), when I open it in WordPad, text looks like abracadabra. As I know, it must be in base64 format. I found an online converter, which let me insert text directly from old .resx file, I got output base64 text and insert it between tags in code above.

Now I see ImageStream in new ResourcesManager in other, however its type is none/null, but it should be System.Windows.Forms.ImageListStreamer

How to convert ImageStream ver 2.0.0.0 to 4.0.0.0?
