Determine whether .NET assemblies were built from the same source

Question

Does anyone know of a way to compare two .NET assemblies to determine whether they were built from the \"same\" source files?

I am aware that there are some differen

When comparing class libraries with ILDasm v4.0.319.1, it seems that image base is not initialized. To avoid mismatches, use a revised solution:

ildasm /all /text assembly.dll
| find /v "// Time-date stamp:"
| find /v "// MVID:"
| find /v "// Checksum:"
| find /v "// Image base:"
> assembly.dasm

Entry point (image base) is actually interesting information for executable assemblies, and will have to be verified carefully. Injecting a new image base is a common way to make a program do something entirely else. In my case, I am trying to verify consistency of multi-threaded builds, so it's safe to skip over the entry point.

A note on performance: I took an 8MB DLL that was built for AnyCPU, and ran ILDasm. Resulting file was 251MB in size and took several minutes to make. Roughly 32x the size was produced.
