Understanding IEnumerable Serialization Naming Issues in ASP.NET Core MVC

When working with object serialization in ASP.NET Core MVC, developers often encounter unexpected behaviors, especially when dealing with properties defined as IEnumerable. One common issue arises when the property names within an IEnumerable do not conform to the specified naming strategy during JSON serialization. This can lead to confusion and extra debugging time. In this guide, we will discuss the problem in detail and provide clear solutions to ensure that your serialized objects maintain consistent naming according to configuration settings.

The Problem

Imagine you have a class that contains an IEnumerable property. Despite configuring a naming strategy—like Camel Casing—when the class is serialized to JSON, the properties within the IEnumerable are not following the desired naming convention. For instance, you might expect the serialized output to look like this:

However, you might end up with:

This inconsistency can be quite frustrating, especially if you've already implemented the naming strategy in your configuration. Let's explore why this happens and how to resolve it effectively.

Why This Happens

After thorough investigation, it appears that this issue stems from how certain libraries—specifically Telerik KendoUI for ASP.NET Core—handle serialization. Instead of utilizing the configured settings directly for serialization, some libraries may manually serialize their settings object, bypassing your configuration altogether. This results in the naming discrepancies you see in the serialized output.

To illustrate, consider the code snippet below that demonstrates the incorrect serialization:

The output here shows the naming convention for properties within Items isn't respected.

Solution: Configuring Serialization Correctly

Step 1: Use JSON.NET Serializer Settings

To ensure that your serialization respects the naming convention, you can manually configure and use the JSON.NET serializer settings. You have already set up Camel Casing; however, make sure you retrieve these settings correctly during serialization.

Sample Code for Correct Serialization

Expected Output

Now, when you serialize vm.Items using the correct settings, you should expect the output to adhere to the naming conventions:

Conclusion

In conclusion, problems with IEnumerable serialization naming conventions in ASP.NET Core MVC can arise from library-specific behaviors, such as those seen in Telerik KendoUI. By ensuring that you retrieve and utilize the correct serializer settings during your serialization process, you can avoid these pitfalls and produce the expected JSON output. Keep these configuration settings in mind whenever you face serialization issues related to object properties, and you'll improve both your development experience and application performance.
