It won't, I don't know what Pavel is talking about. The C++ .NET shim
will know about both the C# object and the C struct with the variable
length or whatever problem is being faced here. The C++ code does the
dirty work, the C# gets handed a "clean" object that has all the
marshaled data.

Because of presence of native code.
To achieve exact arch specific data layout, you must be native code.
Otherwise it would be possible in pure .net languages without any marchaling
headache.

(OTOH, I've seen c# samples on codeproject that simply parse a binary struct
byte by byte, without using .net methods )

So, all native code is unsafe? :-) Windows kernel, shell, and so on?

Well, the matter of taste. I would create a native wrapper DLL instead.

Sure... we get a handful of evidence, every patch tuesday.

Me too. But managers tend to see "purity" of managed code as value.
If such a wrapper DLL will be the only native piece in the project, chances
are it won't be approved.
