I have a web application that is created with mvc asp.net and angular.js in visual studio.. So I am trying to make a treeview in one of my views I searched the internet and I found this amazing library Angular Material I saw some examples and when I opened the source. I found that is contained from html css ts code... I am using angular in my application but I don't have any idea about typeScript files or how to use it !!! Can anyone help me in applying these examples into my application and where can I put the .ts scripts ????
Thank you
