Denis,

It could be one of two things (or maybe even both <g>):

Sometimes VS gets confused with it's namespaces, particularly when dragging controls from the ToolBox for controls in the same namespace. After dragging a control onto your form, do a quick check of the references in the project and be sure you don't have any doubled-up references or ones with that double namespace that you've seen. If you do, simply remove the bad ones.

Also, check the namespaces of your projects ... right-click on the project, go to Properties and verify that you have the Default Namespace specified correctly.
