What has managed code achieved?

Hi

What are the advantages actually achieved of managed code? I am not talking
of theory but in reality.

Thanks

Well, for a start, you get to be introduced to www.google.com.

As your managed code runs under supervision of CLR, it's well-
maintained for .NET framework and the concepts what .NET includes such
as performance, compatibilty and security.

If you think about VB 6.0, which was not managed, developers had to write
lots of extra code that didn't necessarially have anything to do with the
programming problem. Developers had to write extra code to ensure memory
was managed correctly (set x = Nothing) and if they didn't, the program
would develop memory leaks. Developers also had to write addional code to
handle certain security and performance issues as well.

In the managed environment of the .NET CLR, much of this work is
automatically managed by the CLR through its code access security, garbage
collection, & MSIL.

The real, tangible advantages are that less code is written and that the
resulting programs are more robust and cross-language compatible.

Imho, the greatest achievement for managed code is: it gets rid of "dll hell".

There's also automatic memory management, platform-neutrality, and cross-language integration.

Performance benefits are gained from executing all code in the CLR.
Calling unmanaged code decreases performance because additional security checks are required.

Other performance advantages are available through the use of the Just-In-Time compiler,
with gains in built-in security by using code access security and the avoidance of buffer overruns.

But have we traded one kind of DLL hell for another? How many versions of
the Framework are loaded on your system? How is COM-based DLL management any
different than GAC-cached modules that can be replaced without retesting the
consumer applications? Since we now must wait while the code is compiled
before it can be executed, the performance argument might not hold water for
some applications. Notice how long it takes to launch the Report Manager...
I expect that managed code has managed to disenfranchise a lot of perfectly
good COM developers...

I think this depends on whether or not your regard the problems with the GAC
as another type of DLL hell,as it sounds like both I and Bill do. ;-)

For most, however, this is a definite advantage, as most do not use the GAC
much and those who do know how to version (maybe?).

Less Blue Screens by junior developers. ;-)

Realistically, from my COM days, the biggest real world advantage is not
having to register everything and the pain associated with registering
development builds to properly test.

Of course, if you use MTS, you had the option of dropping the running
process and droppping a new COM DLL over the old DLL. But this was thinking
WAY outside the box. You also ended up having to add the weight of MTS to
your app. Not too bad with web apps, which already had most of the weight.
Not as exciting for other apps.

With .NET, however, you can do this without a kludge. So that is a real
world advantage.
