How do I create button with rounded corners/edges on Winform C#?

Question

Well I'll be putting an image on the button, and that image has rounded corners. How do I make this happen? I've been googling and searching for hours, still no luck on it.

You can use the rectangle shape from Microsoft Visual Basic PowerPacks.

There is documentation at How to: Draw Shapes with the OvalShape and RectangleShape Controls

I checked it works in a C# Windows forms project in VS2013 Express for Windows Desktop on Windows7 x64, targeted at both x86 and x64. User xam reports that it also works with VS2017.

private void rectangleShape1_Click(object sender, EventArgs e)
{
    MessageBox.Show("Click!");
}

For convenience, you can add a new Toolbox tab and add the VB PP controls to it.
