Microsoft .NET pros and cons : Phorum 5
If you want to do anything at all serious with graphics you have to go to unsafe code to get any kind of reasonable performance. A simple app that calculated the average color ranges of images, resized them and composed them into a Pixelated larger image (http://www.wiseley.com/ben/picpix) took hours to run until I converted it to unsafe code at which point it ran in under a minute. The pigware factor seems to be pretty severe in .NET, but, I guess, compared to Java, it's not all that different.
This is for discussion about the benefits of .NET vs Win32 or other programming platforms such as Java.

.NET allocates memory automatically and uses garbage collection to free memory occupied by objects that are no longer in use. There are three main advantages as I understand it:
1. The programmer no longer needs to write code to allocate or free memory, which increases productivity.
2. Certain kinds of programming error, such as buffer overruns, are not possible.
3. Certain kinds of memory leaks are prevented.
Note that it is still possible to leak memory if your application holds onto increasing numbers of object references. So garbage collection is not a cure-all; but the benefits are still real.

The shortcoming of the automatic memory management is the performance, e.g. it needs more time to run the program. Especially in the so called component programming language it is worse than commen language(e.g C, C++)Tim wrote:
