Summary

WPF developed by C# can be used as a tool for non-professional developers. After all, the PC desktop development market is in a bad state.

But aside from the influence of market economy, the development mode of C# markup language and Android development have the same effect. The design with the same goal will not only meet the different scenes, but also wonder whether it will bring more profound cognition to programming itself.

Just like the mooncakes just after the Mid-Autumn Festival, if there are 10 kinds of mooncakes in front of you, there are 10 kinds of mooncakes in each kind, but only 10 kinds of mooncakes can be eaten. Suppose you have never tasted the mooncakes, would you try every kind of mooncakes?
