Phaser 3 includes support for dotnet and c#, however you will face major challenges trying to force phaser 3 into an existing mvc or core project. My advise is look up "https://phaser.io/" with out quotes of course. And start with their recommended commercial IDE if you are going to deploy for commercial use. If this is only for education purposes then, I suggest you download latest phaser.js or phaser.min.js you can get both depends how much of phaser you will apply in your project. exercise caution as you click on the links on phaser 3 webiste, they have a site named "cesanata" the website was compromised and is blocked by most WAFs.
