Hi,
i'm looking to find out exactly what .net can do for me.

Can anyone post a link to a plain english version of what it can / can't do
etc etc.

Cheers

..NET is a large library software that simplifies writing programs under
Windows. Compared to the Win32 Windows call interface, under .NET you
spend less time on tedious tasks that have to be performed to use the
services that Windows provides and more time actually using those
services to solve your application's problems. Other runtime libraries
that preceeded it, notably the MFC Library, but .NET is much larger and
more complete.

All of this is not completely for free, as you do sacrifice some
measure of efficiency and control over precisely what's going on, but
the trade-off is usually deemed well worth it for the typical business
application.

Where the various efficiencies like memory utilization and speed are
much more critical, say, in a low-level device driver, unmanaged -- and
this word has a particular meaning in .NET -- C or C++ would be more
appropriate tools.

Hope this helps,
gp

Good explanation. Now for me, The differenece (in plain English) between
managed and unmanaged code.

Managed code is code that is run in a virtual machine environment, where
specific rules and constraints have been placed on the code, and specific
features of the environment are routinely used by the code. Managed code is
encoded in an intermediate language (MSIL for .Net, Bytecode for Java) that
the virtual machine can understand by a compiler that understands the
capabilities of the virtual machine environment.

Coding in this manner provides a controlled space in which to operate,
allowing the software developer to know, for a fact, that some of the
difficult problems typical of prior coding paradigms have been solved for
them.

Managed code is managed for the developer, not the user.

Unmanaged code is coding that is run directly by the operating system, and
calls traditional libraries in a less constrained environment. In this
environment, the programmer takes on the additional responsibility for the
tasks that could be provided by a managed environment. In exchange for
taking on additional dev responsibility, the code usually runs a bit faster
and can often access hardware resources more readily. For business
applications (GUI apps and Web apps) the difference is nearly never
noticable. For intense applications, like gaming environments, CAD systems,
real time device control, among others, sophisticated environments already
exist that perform the common tasks required by developers, so their
advantage in moving to managed code is substantially less, and the
performance cost of the constrained virtual machine may present a greater
obstacle.

I hope this helps,

I would have to take issue with only one point (gaming software) here.
Managed DirectX, from personal experience, is nearly as fast as unmanaged
DirectX. It is not a wrapper for DirectX, and it sits just above the
Hardware Abstraction Layer, just like unmanaged DirectX. And, since both
rely for the most part on the graphics card to do the heavy lifting, there
is little performance difference between them.

The shortest distance between 2 points is a curve.

My apologies. You are correct, the gaming framework has moved successfully
to managed code.
