Serialize the HTTP content to a string as an asynchronous operation. no-recent-activity packaging Related to packaging Often you have an object that you wish to convert to JSON before sending it. Alberto De Natale is a passionate tech-enthusiast software developer. ObjectContent simply allows a "wider" range of types to be sent via HttpClient, while StringContent is narrower for string values only, such as JSON. This code works perfectly but, as I stated in the previous post, working with strings this way can have a negative effect on memory usage, and, at the end of the day, on performance. For receiving a JSON request, it is important to mention or tell the browser about the type of request it is going to receive. Introduction.NET 5 brings interesting new features.
