These days I'm using LINQPad to view the IL quickly.
Here is the alternative to that hectic setup, Sharplab.
SharpLab is developed by Andrey Shchekin. SharpLab is a similar tool you can use to Run, De-compile (C#, IL, JIT Asm) and visualizing syntax trees. You can also switch the C# language to whatever you want in SharpLab.
And the good thing about SharpLab is that you don't need any tools except a web browser.
