Download ILSpy (Latest 2021) for Windows 10, 8, 7

Are you a .NET developer? Do you enjoy dissecting applications and finding specific information about them? If so, then you will want an application like ILSpy which can analyze programs developed in .NET and inspect all of their components. This way, you can determine how the program was originally assembled.

ILSpy is a better tool than its competitors because it is free and easy to use. It is also an open source program that does not require installation. As it is a portable application, you can run it from a USB flash drive, an external hard drive or a personal computer just the same.

Find .NET Assemblies

When you start the application, the main window is clear and has 2 windows. The first window lets you view .NET assemblies in a tree. This way, you can view a selection item more carefully. You can also check WINMD, DLL and EXE files. GAC data can be loaded and you can also open Nuget packages.

The application can code IL, C # and IL with the code C #. If you are assigning C #, your choice is between C # 1.0 / VS .NET and C # 7.2 / VS 2017. You will be able to view reports, resources, tables, and export information to a file.

Performance code

The application is designed for viewing purposes only. For this reason, files cannot be modified. However, you can use a search function to find specific members, types, fields, methods, events, properties, metadata, or constants.

You can configure many decoder settings, such as variable debugging symbol names, dead code elimination, side effect code elimination, and member definition extension after decompression. Also, multiple instances are allowed and the font is customizable.

In total, ILSpy allows .NET disassembly to be quite simple. It is easy for developers to modify existing code and use it for their own purposes, because it is an open source program.
