In windows:

private void uploadButton_Click(object sender, EventArgs e)
{
    var openFileDialog = new OpenFileDialog();
    var dialogResult = openFileDialog.ShowDialog();    
    if (dialogResult != DialogResult.OK) return;              
    Upload(openFileDialog.FileName);
}

private void Upload(string fileName)
{
    var client = new WebClient();
    var uri = new Uri("https://Computer2/UploadedFile/");  
    try
    {
        client.Headers.Add("fileName", System.IO.Path.GetFileName(fileName));
        var data = System.IO.File.ReadAllBytes(fileName);
        client.UploadDataAsync(uri, data);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

In server:

[HttpPost]
public async Task<object> UploadedFile()
{
    var file = await Request.Content.ReadAsByteArrayAsync();
    var fileName = Request.Headers.GetValues("fileName").FirstOrDefault();
    var filePath = "/upload/files/";
    try
    {
        File.WriteAllBytes(HttpContext.Current.Server.MapPath(filePath) + fileName, file);           
    }
    catch (Exception ex)
    {
        // ignored
    }

    return null;
}

I think the problem is that you are not actually sending the file with your UploadFile() method, you are just sending the file path. you should be sending the file bytes.
