At the moment the most popular component MathML.Net is not available for download, I am wondering if there are other .Net components that can help with this issue (can edit formulas, render them as image)
I found "gNumerator" just moments ago, which should render MathML, and it's written in C# for Winforms. I haven't tried using this on my own, but the screenshots look promising.
