Using the ReaderWriterLockSlim correctly and avoiding a common mistake
Some projects suffer from a bad usage of the upgradeable-read-lock. If all the situations involve getting an upgradeable-read-lock to maybe upgrade to a write lock, without ever using simple read locks, there is unnecessary contention, which is worse than using full locks with the lock keyword.

I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.
