  • 0

I thought, one day that I should try out WPF. Turns out I fell at the first hurdle.
I inserted code from an Inkscape generated xaml file, then wrapped it in Viewbox tags. I had the error that it didn’t exist in the namespace.
What am I doing wrong? Do I need some sort of reference?

    With the following steps, I was able to run your sample:

    • Create a new Wpf project;

    • In the automatically created Window that opens, I removed the <Grid></Grid> object;

    • I replaced this with your code sample.

    This works successfully. The following is the result:
