ILDASM

ILDASM is the Microsoft MSIL Disassembler. It is delivered as part of the .NET Framework SDK. This utility is useful for examining the contents of a .NET EXE or DLL file.

To run this program, click Start, All Programs, Microsoft Visual Studio 2010, Visual Studio Tools, and Visual Studio Command Prompt (2010). At the command prompt, enter ILDASM and press the Enter key. The application starts.

You may select File, Open from the main menu to select a file to examine. Alternatively, you can drag-and-drop a file from Windows Explorer to ILDASM to open the file.

When ILDASM has opened a file, you examine the contents of the file by expanding the tree view. Double-clicking the MANIFEST opens a dialog to display several items of interest, including:

The external assemblies and their version numbers that this .NET EXE or DLL references
The version and public key of this .NET EXE or DLL file
