Error CS0246 The type or namespace name ‘InterceptsLocation’ could not be found (are you missing a using…

Starting with .NET 8 you can mark JsonSerializerOptions instances as read-only, preventing further changes to the instance. To freeze the instance, simply call MakeReadOnly on the options instance. Let’s take an example: Furthermore, you can check if an instance was frozen or not by checking the IsReadOnly property. Attempting to modify a JsonSerializerOptions instance after…

System.Text.Json brings out of the box support for additional types: Let’s look at an example:

Starting with .NET 8, both Memory<byte[]> and ReadOnlyMemory<byte[]> are serialized as Base64 strings. Let’s look at a quick example: In contrast, Memory<int> and the likes will continue to be serialized as JSON arrays.

The attribute works with any non-public modifier, such as private, protected or internal. Let’s look at an example: As expected, this will output the following:
