PostAsync. The only solution I found was very similar - I moved to the 'PostAsync' method but using a 'StringContent' object. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. When dealing with serialized payloads, it's easier to just use StringContent to allow using different serializers. Alberto De Natale is a passionate tech-enthusiast software developer. If you want to use it in web api, you should create the response with the string content. ObjectContent simply allows a "wider" range of types to be sent via HttpClient, while StringContent is narrower for string values only, such as JSON. private static async task postbasicasync(object content, cancellationtoken cancellationtoken) { using ( var client = new httpclient ()) using ( var request = new httprequestmessage (httpmethod.post, url)) { var json = jsonconvert.serializeobject (content); using ( var stringcontent = new stringcontent (json, encoding.utf8, "application/json" )) You simply provide the StringContent object to the "PutAsync" or "PostAsync" method along with an URL and then you have sent a request with a body containing JSON.
