I can’t understand why If I compile the same source with Visual Studio 2008 (MSBuild) and then with csc (or NANT) at command line I can’t obtain exacly the same binary file (the same assembly).
The command line is the same that is invoked by visual studio because I copy the command from the output window and then paste the command to the vs2008 command prompt.
I know that if I compile the same source at different time I obtain different binary because of the timestamps in the assembly metadata. In fact, if I compare two binaries produced by vs2008 at different time I notice small difference between the binary data.
But if I compile with vs and then with csc the binaries are very very different!
Do you know why? What’s wrong?
There’s no guarantee of any particular order of metadata made by the compiler. That said, there’s nothing intentionally causing a different ordering between the in-proc compiler and csc.exe.
