Here another way to get non expiring token and upload track to SoundCloud using C#:

public class SoundCloudService : ISoundPlatformService
{
    public SoundCloudService()
    {
        Errors=new List();
    }

    private const string baseAddress = "https://api.soundcloud.com/";

    public IList Errors { get; set; }

    public async Task GetNonExpiringTokenAsync()
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri(baseAddress);
            var content = new FormUrlEncodedContent(new[]
            {
                new KeyValuePair("client_id","xxxxxx"),
                new KeyValuePair("client_secret","xxxxxx"),
                new KeyValuePair("grant_type","password"),
                new KeyValuePair("username","xx@xx.com"),
                new KeyValuePair("password","xxxxx"),
                new KeyValuePair("scope","non-expiring")
            });

            var response = await client.PostAsync("oauth2/token", content);

            if (response.StatusCode == HttpStatusCode.OK)
            {
                dynamic data = JsonConvert.DeserializeObject(await response.Content.ReadAsStringAsync());
                return data.access_token;
            }

            Errors.Add(string.Format("{0} {1}", response.StatusCode, response.ReasonPhrase));

            return null;
        }
    }        

    public async Task UploadTrackAsync(string filePath)
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress=new Uri(baseAddress);

            var form = new MultipartFormDataContent(Guid.NewGuid().ToString());

            var contentTitle = new StringContent("Test");
            contentTitle.Headers.ContentType = null;
            form.Add(contentTitle, "track[title]");

            var contentSharing = new StringContent("private");
            contentSharing.Headers.ContentType = null;
            form.Add(contentSharing, "track[sharing]");

            var contentToken = new StringContent("xxxxx");
            contentToken.Headers.ContentType = null;
            form.Add(contentToken, "[oauth_token]");

            var contentFormat = new StringContent("json");
            contentFormat.Headers.ContentType = null;
            form.Add(contentFormat, "[format]");

            var contentFilename = new StringContent("test.mp3");
            contentFilename.Headers.ContentType = null;
            form.Add(contentFilename, "[Filename]");

            var contentUpload = new StringContent("Submit Query");
            contentUpload.Headers.ContentType = null;                                
            form.Add(contentUpload, "[Upload]");

            var contentTags = new StringContent("Test");
            contentTags.Headers.ContentType = null;
            form.Add(contentTags, "track[tag_list]");

            var bytes = File.ReadAllBytes(filePath);                
            var contentFile = new ByteArrayContent(bytes, 0, bytes.Count());                
            contentFile.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
            form.Add(contentFile, "track[asset_data]", "test.mp3");

            var response = await client.PostAsync("tracks", form);                
        }
    }
}
