'IUploadClient' does not contain a definition for 'UploadAsync'

'IUploadClient' does not contain a definition for 'UploadAsync' and no accessible extension method 'UploadAsync' accepting a first argument of type 'IUploadClient' could be found (are you missing a using directive or an assembly reference?)

public async Task UploadVideoAndTweetAsync(string filePath, string tweetText)
{
    try
    {
        System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
        var client = new TwitterClient("JQWrqE", "JTCKUGCB8r", "15MTiR", "64rz");

        byte[] fileBytes = System.IO.File.ReadAllBytes(filePath);

        var uploadResult = await client.Upload.UploadAsync(new ChunkUploadParameters
        {
            MediaFile = filePath,
            MediaType = "video/mp4"
        });


        //Console.WriteLine($"Tweet sent! URL: {tweet.Url}");
    }
    catch (Exception ex)
    {
        Console.WriteLine("Invalid casting. {0}", ex.Message);
    }
}

Thanks

Hello! It looks like you are encountering an issue where the 'IUploadClient' interface does not contain a definition for 'UploadAsync' in your C# code snippet. This error typically occurs when the method 'UploadAsync' is not defined within the 'IUploadClient' interface or the necessary using directive or assembly reference is missing.

To resolve this issue, you need to ensure that the 'UploadAsync' method is either implemented in the 'IUploadClient' interface or provided by a class that implements this interface. Additionally, make sure that you have the correct using directive or assembly reference for the class containing the 'UploadAsync' method.

Here's a general approach to address this problem:

1. Check the 'IUploadClient' interface and the class that implements it to see if the 'UploadAsync' method is defined.

2. Verify that you have added the appropriate using directive for the namespace where the 'UploadAsync' method is declared.

3. Ensure that the assembly containing the definition of 'UploadAsync' is referenced in your project.

By following these steps, you should be able to resolve the issue related to 'IUploadClient' not containing a definition for 'UploadAsync'. If you have any specific questions or need further assistance with your code, feel free to ask!

Let me know if you need additional clarification or assistance with any other related matter.
