Any experienced .NET developer knows that even though .NET applications have a garbage collector, memory leaks occur all the time. It’s not that the garbage collector has bugs, it’s just that there are ways we can (easily) cause memory leaks in a managed language.

Memory leaks are sneakily bad creatures. It’s easy to ignore them for a very long time, while they slowly destroy the application. With memory leaks, your memory consumption grows, creating GC pressure and performance problems. Finally, the program will just crash on an out-of-memory exception.

In this article, we will go over the most common reasons for memory leaks in .NET programs. All examples are in C#, but they are relevant to other languages.

At work, we are planning to migrate our WPF application from .NET Framework 4.7 to .NET Core 3.0. The main reason for doing so is that it was always a big pain to organize the updates of the .NET Framework on our customer machines. So being able to bundle .NET Core with our application is a big plus for us. Then, for sure, we are looking for the performance improvements brought by .NET Core and finally the new capabilities brought by the fast pace of innovation of .NET Core.

In this post, I will describe how to port a desktop application from .NET Framework to .NET Core. I picked a WinForms application as an example. Steps for WPF application are similar and I’ll describe what needs to be done different for WPF as we go. I will also show how you can keep using the WinForms designer in Visual Studio even though it is under development and is not yet available for .NET Core projects.
