HTTP PATCH Requests (Partial Updates) in ASP.NET Web API and EF DB First

To update an entity in ASP.NET Web API, PUT request is used and we have to send all the properties even if only a subset have changed means if only one field is updated on the client side, we have to send the entire model back to the server to make an update. It’s not a cool way. PATCH request allows you to send just the modified properties for partial model updates. It reduces complexity in case of bigger tables. Here is a usage example to implement HTTP Patch request in ASP.NET Web API to update data with EF DB First.
