Making an exe that doesn't need .NET frameworkHi,
I never understood how can it be that most programs don't ask me to install .NET, although I know that many companies use C#. Is there any way to make an exe of a C# program that doesn't need .NET to be installed? If so, how can I do it? Thanks, Ofir.

If so, how can I do it? technically require .NET, it does require a host platform that provides the same functionality. You can read about this in the official C# standard and other sources. Search for ISO/IEC 23270, "CLI, "CLR", "CLS", etc. For all intents and purposes however .NET is really the only game in town (on Windows anyway - you can read about the Mono project and others however). If an installation program isn't asking you to install it then it either assumes it's already installed (very good chance these days), will be installed (manually), or it's specifically checking that it's installed (note BTW that it's shipped with the latest MSFT OSs but may not be installed by default - it can be installed using the "control panel" however). In any case, you can't run your program without it, even if you find "tricks" that rely on it indirectly. You might find "ngen.exe" interesting for instance but all this does is JIT-compile your code up front. "Larry Smith" <_nospam@_no_spam.com> wrote in message

While it technically can be done using a 3rd-party product like the one you cited (compiling your managed app into native code ahead of time), this is no longer a .NET app on the client's machine anymore (which is what the op was presumably asking about). It's also risky IMO so I agree with your original comment. It's a "complete waste of time and money".

It is true that a substantial number of XP installations have a version of .NET installed for one reason or another. I am not sure if the total qualifies as vast majority or not. It is a common myth that .NET is installed with one of the service packs for XP (SP2, SP3)--it is not. It is a common myth that .NET is installed automatically as part of a Critical or High Priority Automatic Update to XP--it is not. There may be some OEMs that include .NET as part of their standard XP image, however, I am not able to verify that at the moment. It is logical since some third-party software that OEMs load need .NET to run. One interesting anecdote. I recently purchased a Samsung netbook with XP Home SP3 pre-installed. No .NET. If you have MSDN or similar you may want to download one of the XP install images as an experiment. Load it in a VM, and notice that there is no .NET framework. J Because of the same reason they never ask you to install a video driver.
Cor If you like the convenience and simplicity of coding in C# but don't want to use .NET, the way to go
might be to use something like Delphi.
