Service Fabric Handbook


This post is a handbook where you probably will find an answer to “How different things works in Azure Service Fabric?” question. Almost all of the information (around 90%) is from docs.microsoft.com, GitHub and etc., the rest of it are personal findings made during development of CoherentSolutions.Extensions.ServiceFabric.Hosting.

Where possible the information will be confirmed by reliable source (docs, issues or posts).

.NET R&D Digest (September, 2019)

What is the difference between ToArray and ToList?


In the beginning of June I attended .NET Summit conference in Minsk, Belarus. Besides interesting presentations (recording are available on YouTube, language is Russian / English) there were interesting quizzes.

One of the questions was:

What is the difference between ToArray and ToList?

Software Engineer

Hmm… what could be the difference besides one returns T[] and another one returns List<T>?

If you don’t know the answer or just like digging into sources of dotnet/corefx then I invite you to join me and find out the answer!


All code snippets were taken from release/3.0 branch of dotnet/corefx repository. All code snippets were truncated to make them more representative (removed input argument checks, contracts, …, etc.).

.NET R&D Digest (April, 2019)

There are a lot of good technical articles & books on Web. I see them all the time – when trying to find a solution, when investigating things or simply when reading new posts from my RSS Feed during breakfast.

Having all these knowledge only for myself was a bit selfish. That is why once a month or two I compose some of this content into a so called ‘digest’ for colleagues & friends.

After fourth issues (this one is the fourth) I though – maybe this can be interesting for my readers? So this is the Aprils issue of .NET R&D Digest.
