Are .NET applications a natural amount of memory?

I started writing a great C # application for the first time in my life. I wrote a sample module to test the idea of ​​my software. This module contained dozens of C # dictionaries and lists of objects, each of which had several elements and properties.

I was shocked that after initializing the main objects, about 40 MB of RAM is ultimately used.

I tested and found out that after the initialization of the object more than 30 MB is allocated, but I got the impression that, taking into account the size of my objects, it was necessary to consume no more than several hundred kilobytes.

Am I doing something wrong or is .NET naturally more memory intensive compared to native code applications?

Using task manager to view your memory usage is likely to be terribly inaccurate.

Instead, grab the proper memory profiling tool ( dotTrace is very good and has a 10-day trial) and take the time to see your actual memory consumption.

Views I've seen in my own code include

  • Underestimate how much memory I use (not counting individual objects properly, not allowing lists to have "spare" capacity)
  • Saving references to temporary objects that I do not need.
  • Do not allow temporary objects created during operation that have not yet been garbage collected.
