This language gets executed by the Common Language Runtime (CLR), which is an application virtual machine that provides memory management and exception handling.

.NET file structure

The .NET file structure is based on the PE structure that we described in Chapter 3, Basic Static and Dynamic Analysis for x86/x64. The .NET structure starts with a PE header that contains the last but one entry in the data directory pointing to .NET’s special CLR header (COR20 header).

.NET COR20 header

The COR20 header starts after 8 bytes of the .text section and contains basic information about the .NET file, as shown in the following screenshot:
