C# WPF on VB.Net Form

[k3nnt0ter0]

How do I embed the WPF I created in C# to VB.Net Forms? If I remember, the DLL should be added as reference in vb.net. I tried that and I tried to add tools in toolbox but I can't see the WPF I created in toolbox.

I successfully added the WPF on VB.Net but I got an error.
