[Mono-list] could linux be MORE .Net then windows ?

[Kornél Pál]

Hi,

You don't have to have a look at the source code to determine whether Visual 
Studio 2005 uses managed code.

You missed the fact that Visual Studio 2005 is much more than a single 
devenv.exe. It has a lot of DLLs and supporting exe files and a lot of them 
are entirely managed assemblies.

Also note that if you interact with managed code using CorBindToRuntimeEx() 
for example the unamanged code that interacts with managed code won't became 
managed code. Managed code is IL code.
