[.NET Internals 05] Garbage collection: marking, collection and heaps compaction

Today, in the next article from .NET Internals series on my blog, we’re going to investigate how the garbage collector (GC) actually releases the memory (which is its main purpose as could be read here), what is marking phase and how the managed heaps are compacted in order to optimize the process. We’ll also see when may the collection be triggered.

Xamarin.Android – ASP.NET web api synchronization – research

Recently I’ve added an ASP.NET Core web solution to my GitHub repository in order to create back-end API for my mobile app. I wanted to have database hosted on a remote server and Android application to synchronize its data with it. Then I started wondering… and decided to make a deeper research first. As I wrote in my post summing up DajSiePoznac2017 competition, “before using a particular solution for an issue” we should “better examine the other possibilities” first. So I do 🙂 Continue reading
