In the same code file would not work cause you would need to know where
language A ends and language B begins. The compiler would need to parse
the file and know what language to pass to based on some sort of
lookup.
In .NET 2.0 there is the notion of "partial" classes where for example
XAML files describe one part of the class and say a VB file describes
another. But again the languages they are compiled with must be the same
(Example: http://www.devx.com/dotnet/Article/22603/1954?pf=true )
The other thing you have is multi-assembly namespaces. So that part of
a name space is in one assembly and another part is in another assembly.
So one assembly could be written in C# and another could be written in
VB. but again these are separate files and separate assemblies.

Yes, its true that any .NET language should be able to
use any other .NET language (in separate assemblies).
This IS supported by the standard and is one of the
major motivations for the CTS (common type system), a
significant part of the CLI (common language
infrastructure).
However, it should even be possible to support
multiple languages in the same assembly, assuming the
compilers could agree on an intermediate target or
some method for merging the assemblies. I don't
believe this has been done, but I think its certainly
possible (not sure it buys anything though).
That being said, the question was about mixing code in
a single source file. I don't think this should be or
would ever be possible.
