By which I can replace the use of ATL to have an equal or a better performance?

Question

I'm new to ATL developement. Refering to some links in the Net, COM is outdated by .NET.

Is there any technologie that replaces ATL?

ATL is basicaly used to build fast and small apps. Does .NET build smaller and faster apps?

What's the difference between building raw C++ .EXE apps and ATL .EXE apps, please?

Answer 1

ATL is just a framework / library on top of C++. At the end of the day there is no fundamental difference between a plain old C++ app and an ATL one. An ATL tends to associate with COM programming but that is not a necessity.

.Net on the other hand is a completely separate runtime. It compiles down to IL and runs in a virtual machine (the CLR).

As to which is smaller or faster. There are no hard truths here but in general

• C++ EXE / DLL tend to be smaller for equivalent size apps
• C++ startup time tends to be faster than .Net because it doesn't need a JIT
• .Net apps tend to have less issues around memory management, leaks and corrutpion as copmared to C++
• Languages targeting .Net tend to be easier to learn than C++
