This online tool can help you to understand how C# source code works with the Just-In-Time compiler(JIT) and the Intermediate Language (IL) code generated by the C# compiler. If you switch to decompile to C# you can see more information about this simple example. This decompiles C#, compiles code, then… Continue Reading C# – First steps with C# and .NET – part 042.

        Console.WriteLine("TIME: " + time);
    }

The result is this:

In this tutorial, I showed the first steps with C # and Avalonia. Today I will show you how to change the formula. For example, a simple button can be integrated into the application with the following mechanism. The XAML uses an Avalonia {Binding} to bind the Button’s Content property… Continue Reading C# – First steps with C# and .NET – part 039.
