What is managed code and
managed data?<o:p></o:p>
Managed code is code
that is written to target the services of the Common Language Runtime (see What
is the Common Language Runtime?). In order to target these services, the code
must provide a minimum level of information (metadata) to the runtime. All C#,
Visual Basic.NET, and JScript.NET code is managed by default. Visual Studio.NET
C++ code is not managed by default, but the compiler can produce managed code by
specifying a command-line switch (/CLR). <o:p></o:p>
Closely related to managed code is managed data?data that is
allocated and de-allocated by the Common Language Runtime's garbage collector.
C#, Visual Basic, and JScript.NET data is managed by default. C# data can,
however, be marked as unmanaged through the use of special keywords. Visual
Studio.NET C++ data is unmanaged by default (even when using the /CLR switch),
but when using Managed Extensions for C++, a class can be marked as managed by
using the __gc keyword. As the name suggests, this means that the memory for
instances of the class is managed by the garbage collector. In addition, the
class becomes a full participating member of the .NET Framework community, with
the benefits and restrictions that brings. An example of a benefit is proper
interoperability with classes written in other languages (for example, a managed
C++ class can inherit from a Visual Basic class). An example of a restriction is
that a managed class can only inherit from one base class.

hi all
i have a small confusion
regarding managed data....
see managed code is the code which
makes use the CLS feature of the clr and the which undergoes
through the managed execution processs .In this all the features
of clr like cts, cls,cas, msil , jit all takes place for the
fullest performance/security execution of the code.
but
where does this managed data come in ???
is it like this "the
objects which are inherited from other languages apart from the
one you use
and acted upon by garbage collector"?
where
exactlly this manages code DIFFER from MANAGED
DATA????
