.NET Framework

As of now UnoViewer is compatible with following .NET framework versions:

• .NET 4.8: This is the legacy .NET version which is still very popular. Also known as the WebForms version of Asp.Net. It works on the Windows platform only.
• .NET 6.0: Though now out of support, .NET 6.0 is widely used and deployed version of .NET. It uses the new MVC project style with StartUp class and the dependency injection pattern. Again, it uses System.Drawing which works on the Windows platform only.
• .NET Standard 2.0: This version supports cross platform deployment (Window, Mac, Linux, Docker) without having the System.Drawing dependency. It uses the cross platform SkiaSharp graphics library from Microsoft.
