Examples
This sample shows how to call GetUpdateAsync with required parameters and parse the result.
var credential = new DefaultAzureCredential();
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new DeviceUpdateClient(endpoint, "<instanceId>", credential);
Response response = await client.GetUpdateAsync("<provider>", "<name>", "<version>");
JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("compatibility")[0].GetProperty("<test>").ToString());
Console.WriteLine(result.GetProperty("manifestVersion").ToString());
Console.WriteLine(result.GetProperty("importedDateTime").ToString());
Console.WriteLine(result.GetProperty("createdDateTime").ToString());
