What is the recommended technology/development framework for customers who want to migrate applications from Silverlight?
There are various options for migrating applications from Silverlight. We recommend that you evaluate the requirements of the application that you are migrating and determine the technology that best suits the application in question:
If your application is non-browser dependent and you’d like to migrate to a Windows Desktop application, we recommend you migrate your application to UWP or WPF on .NET Core.
If your application is web-based, we recommend that you look into Blazor, which allows re-usability of .NET Silverlight code. Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code are written in C#, allowing you to share code and libraries.
Silverlight is a free plug-in, powered by .NET framework and works with most web browsers, devices and operating systems. It is a useful application which creates engaging, interactive user experiences for Web and mobile applications.
