Do we really support application/xml?

[darrelmiller]

The default value for --structured-mime-types includes the following:

  "structuredMimeTypes": [
    "application/json",
    "application/xml",
    "text/plain",
    "text/xml",
    "text/yaml"
  ],

Do we really support serialization of application/xml? Are the text/yaml and text/xml processed by the text serializer? Does the method signature accept/return as a string?

We support the generation of models. However we don't have serialization and deserialization implementations today.

FYI I've removed those mime types from the default supported ones in #2078
I guess we should now rename this issue to add serialization support for those types.

[darrelmiller]

I am happy with this change. I don't believe we need to have inbox support for XML.

@darrelmiller is there documentation around creating and registering custom serializers for Kiota that you could share? Our team has just hit a situation where we wanted to use Kiota proxies with a XML-based API.

From your comment above, I assume creating a serializer for XML and plugging it in should be a supported extension point.

For serialization you would need to implement these two interfaces.

• https://github.com/microsoft/kiota-dotnet/blob/main/src/abstractions/serialization/ISerializationWriter.cs
• https://github.com/microsoft/kiota-dotnet/blob/main/src/abstractions/serialization/ISerializationWriterFactory.cs

For deserialization

• https://github.com/microsoft/kiota-dotnet/blob/main/src/abstractions/serialization/IParseNodeFactory.cs
• https://github.com/microsoft/kiota-dotnet/blob/main/src/abstractions/serialization/IParseNode.cs

Once this is done, you will register the serializer and deserializer as is done here with the client and you should be able to make requests.

You can also checkout the example implementation for form serialization here for inspiration.
