This is with your example and sample, same error...maybe I am doing something wrong..I am using this:

static public void PostFromweb()
{
var jsonParams = JsonConvert.SerializeObject(new

gripper_offset = 0.01,
palm_depth = 0.05,

}
});
var jsonContent = new StringContent(jsonParams, Encoding.UTF8, "application/json");
using (WebClient webClient = new WebClient())
{
string s = webClient.DownloadString("http://automation.berkeley.edu/dex-net/assets/pawn/pawn.obj");
var bytes = System.Text.Encoding.UTF8.GetBytes(s);
var meshContent = new ByteArrayContent(bytes);
var form = new MultipartFormDataContent();
form.Add(meshContent, "file", "file");
form.Add(jsonContent, "params", "params");
var uploadResponse = client.PostAsync("upload-mesh", form)
.GetAwaiter()
.GetResult();
uploadResponse.EnsureSuccessStatusCode();
var result = uploadResponse.Content.ReadAsStringAsync().Result;
var anonResponse = new
{
id = string.Empty,
position = -1
};
var deserializedResp = JsonConvert.DeserializeAnonymousType(result, anonResponse);
Console.WriteLine(deserializedResp);
var state = "preprocessing";
while (state != "error" || state != "done")
{
var progressResponse = client.GetAsync(deserializedResp.id + "/processing-progress")
.GetAwaiter()
.GetResult();
progressResponse.EnsureSuccessStatusCode();
var progress = progressResponse.Content.ReadAsStringAsync().Result;
Console.WriteLine(progress);
System.Threading.Thread.Sleep(5000);

}

EDIT: After several clicks.... I have this output:

}

EDIT 2:
Adding this lines to your code works perfectly!
BTW: Beautiful project
while (state != "error" || state != "done")
{
var progressResponse = client.GetAsync(deserializedResp.id + "/processing-progress")
.GetAwaiter()
.GetResult();
progressResponse.EnsureSuccessStatusCode();
var progress = progressResponse.Content.ReadAsStringAsync().Result;
Console.WriteLine(progress);
if (progress.Contains("\"state\": \"done\""))
{
break;

@DiegoVil sounds like you got things working. Glad to help.
@wderose : Yes , its working now...
One more question: I have gone through the paper but I have a doubt.... in the poses that you calculate where is the origin ? in the center of mass of the object? how can I know where is located the basis of coordinates?
The stable pose-associated grasp is relative to the object. We assume the mesh is watertight, so it should be the CoM of the object. In order to use grasp configuration, you may still need to apply a transformation to grasp pose. The quaternion is wxyz.

This is my class... I was doing just a quick test...I have a windows form with 2 buttons, with the first button I upload from my computer and I get an ID from my mesh. Then with second button and a textbox in windows form I add " my commands " to see if it works...
So, my post function returns id and then I send the command with a get
