Serialization in .NET – BinaryFormatter Errors and How To Fix Them!

Serializing data (to save and load it) should be easy. That’s what serialization is all about! In .NET it is really simple to serialize even quite complex networks of objects using the BinaryFormatter class. But the latest versions of .NET warn you that BinaryFormatter is insecure and suggest that you use some different type of serialization such as JSON.

I’ll look at JSON in more detail in future videos. In this lesson, I want to explain what serialization is and how you can suppress the BinaryFormatter errors using the pragma:
#pragma warning disable SYSLIB0011
