But to go deeper to .NET/CLR architecture is important too. Try to understand how it works inside. Use the source, Luke! https://source.dot.net/ https://referencesource.microsoft.com/ This source code vaults is not completed then try JetBrains dotPeek tool to look at any assembly source code.

(https://github.com/Microsoft/referencesource/blob/master/System.ServiceModel/System/ServiceModel/MessageSecurityVersion.cs; scroll down to inner classes)

List is an IList/IReadOnlyList; these interfaces do nothing that couldn't be done right inside the file itself.

Instead we have to go diving through the IList, which implements ICollection, which implements IEnumerable, which implements IEnumerable (again). Just because each interface is composed of another interface, doesn't mean you aren't using inheritance. You are effectively creating a custom inheritance tree through willy-nilly composition.

It is gratuitous to make this chain so deep, when the underlying code is just a handful of lines.

The doc-strings are unnecessary. It's self-evident what most of the code does if you read it.

The whole .net framework source code is online.

.net itself has arbitrary interfaces, ex https://github.com/microsoft/referencesource/blob/master/mscorlib/system/action.cs

Assuming if you are new to C# - start coding! And start reading https://learn.microsoft.com/en-us/dotnet/csharp/tour-of-csha...

If you are not new to C#, start building an application end-to-end/a classic n-tier application, right from using a database, Entity Framework, WebAPI, DTO, AutoMapper, and a front-end (your choice - Angular/React/Vue with TypeScript or better yet - Blazor).

You will not only understand & use dependency injection, reflection, LINQ, multi-threaded programming, generic programming, source-code generation, unit-testing - and much much more in a practical/real-world usage.

Peruse https://referencesource.microsoft.com/ once in a while.

Follow various team members of .NET Framework, C# team and the like on various social-media. https://mobile.twitter.com/i/lists/120961876

I am sure there will be who agree / disagree with the above approach and will provide more viewpoints for you to consider.

Enjoy - and strap yourself for an amazing journey or roller-coaster ride, however you want to call it!

Maybe from the source of FtpWebRequest it is possible to track what the default behaviour is.

The class is just a very limited dictionary, a library will be the same or better.

Let’s look at the first example you see, when you open up BenchmarkDotnet’s website, or Github page.

Or use BenchmarkDotNet which, among other things to get an accurate benchmark, does JIT warmup outside of measurement.

( https://github.com/dotnet/BenchmarkDotNet ).

You can also do proper statistically correct benchmarking by using - https://github.com/dotnet/BenchmarkDotNet. This will run warmup the jit, gauge the overheads, and run your function many times to give you proper data.

take a look at: https://benchmarkdotnet.org/

Yes, weak references are slower than direct calls. How much slower? Heck if I know offhand. But it's usually pretty easy to set up something with Benchmark .NET and find out if it hurts your use case.

For this purpose we are going to use our beloved BenchmarkDotNet tool.

To quantify and compare the performance of the object mapping strategies discussed earlier, we can employ BenchmarkDotNet.

BenchmarkDotNet is a popular open-source library that, as stated in the repo's README.md, helps us to transform methods into benchmarks, track their performance, and share reproducible measurement experiments. Using BenchmarkDotNet feels similar to writing unit tests. It's very important to note that the library only works with console apps. Finally, we can visualize the results in the terminal where the benchmark ran or in user-friendly formats such as markdown, HTML and CSV. We will explore examples of there formats later in the article.

However, obviously this prevents parallelism within the lock, so this only makes sense if you do some other expensive operation in the parallel loop and the string builder is only a small part of it. Performance wise, it may be better to concatenate the results together after the parallel operation, instead of locking inside the loop. You'll have to benchmark it to know for sure.

We’re of course going to be using BenchmarkDotNet for our benchmarks, and you can find all of the code for these over at GitHub. To start, we need an entry point hook for our single Benchmark class that will be defining the permutations of scenarios that we’d like to run. This will be relatively basic as follows:
