C# MagnetLink to torrent file

I am going crazy right now. Since all other questions are several years old and the MonoTorrent developers have gone MIA I really need your help.
What I am really stuck with is parsing the magnet link and downloading it.
This is my code:
public static void DownloadTorrent(string magnetLink)
{
MagnetLink link = new MagnetLink(magnetLink);
//URL stores the magnetlink
EngineSettings settings = new EngineSettings();
settings.AllowedEncryption = EncryptionTypes.All;
settings.SavePath = destination;
string torrentFilePath = torrentDestination;
if (!Directory.Exists(settings.SavePath))
Directory.CreateDirectory(settings.SavePath);
if (!Directory.Exists(torrentFilePath))
Directory.CreateDirectory(torrentFilePath);
//Create a new engine, give it some settings and use it.
ClientEngine engine = new ClientEngine(settings);
engine.ChangeListenEndpoint(new IPEndPoint(IPAddress.Any, 6969));
TorrentManager manager = new TorrentManager(link, engine.Settings.SavePath, new TorrentSettings(), torrentFilePath);
engine.Register(manager);
manager.Start();
Console.ReadLine();
}
And my magnet link is: "magnet:?xt=urn:btih:c6df2f47d033d54b054cafe7ef683ba167222d92&dn=Windows+XP+Professional+SP3+-+Activated&tr=udp%3A%2F%2Ftracker.leechers-paradise.org%3A6969&tr=udp%3A%2F%2Fzer0day.ch%3A1337&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=udp%3A%2F%2Ftracker.coppersurfer.tk%3A6969&tr=udp%3A%2F%2Fexodus.desync.com%3A6969"
Now an error throws on the magnet link saying "No such host is known and referring to udp://exodus.desync.com:6969/"(Visual Studio is on swedish so that might not be a literal translation).
Visual Studio is marking tracker = new UdpClient(announceUrl.Host, announceUrl.Port); as the error source and it's located inside one of MonoTorrent's code files; UdpTracker.cs
I am trying to make a simple application and I am just stuck on this part.
Any help is greatly appreciated. It's one of my first times posting here so if I missed to mention anything just tell me and I will add it.
Thanks on forehand! Also pardon my english, I am not a native speaker.
Update: If you know another way of solving this even without MonoTorrnet - I will take any help I can.

Issues loading different shapefiles in given sharpmap tutorial code

I am currently working on sharpmap project with the need to work on offline maps. As i am fresher in this field,I am following the sharpmap tutorial and facing a problem with loading new shape files in the given tutorial code.
For Example :\
SharpMap.Layers.VectorLayer("States");
vlay.DataSource = new SharpMap.Data.Providers.ShapeFile("path_to_data\\states_ugl.shp", true);
At this line of code, if i pass a different shapefile, code builds with a blank background or no display.
I have tried with different shape files with different sizes but the result is the same. It only works for the mentioned states_ugl.shp file given in the code. Please need help regarding this issue as I am a fresher in this field.
Thanks.

Try giving layer styling for your layer, something like below.
layer.DataSource = DBlayer;
layer.Style.Fill = new SolidBrush(Color.Transparent);
layer.Style.Outline = new Pen(Color.Black);
layer.Style.EnableOutline = true;
layer.MaxVisible = 13000;

Show DevExpress waitform dialog without designer

I'm trying to display a Loading Please Wait dialog form using devex controls and I can't seem to do it. (using winforms, c#)
I'm using an older version of devex - not the latest. I can't do
SplashScreenManager.ShowDefaultWaitForm()
I need to do this in code without the designer.
1.
I tried:
SplashScreenManager.ShowForm(typeof(WaitDialogForm));
It looks right when it loads, but then it throws an error:
Unable to cast object of type 'DevExpress.Utils.WaitDialogForm' to type 'DevExpress.XtraSplashForm.SplashFormBase'
I tried:
SplashScreenManager.ShowForm(typeof(WaitForm));
This shows an empty form thats too big with no image and no text
I tried:
WaitDialogForm mWaitDialog = new WaitDialogForm() {Visible = false};
mWaitDialog.Show();
The wait form doesn't look right. There are white spaces instead of the image.
I tried:
WaitDialogForm mWaitDialog = new WaitDialogForm() {Visible = false};
mWaitDialog.ShowDialog();
The code doesn't continue executing.
I saw examples of
SplashScreenManager.ShowForm(typeof(WaitForm1));
I don't know how to do this without designer.
Can somebody please assist? I thought I'm doing something simple, but I can't seem to figure it out!

Probably this help u ;)
using (new DevExpress.Utils.WaitDialogForm("Please wait"))
{
//Do your stuff here
}

I don't know if this is in your 13.2 version but from looking at documentation you should be using ShowWaitForm instead of just ShowForm.
SplashScreenManager ssm = new SplashScreenManager();
ssm.ActiveSplashFormTypeInfo = typeof(WaitForm1);
ssm.ShowWaitForm();
If that does not work then i would just try preparing a working solution in the designer and then extracting the code from the designer.cs file.
Found a specific documentation example here

why CSCore equalizer SampleFilters[9] (16Khz) does not affect at all in C#

I recently found that if I want to add equalizer to my application I can use CSCore library! I tested it and it's good! but the problem is that 16Khz equalizer Band (Treble) does not have any effect at all!!
What's wrong what should I do?
I even tried real high numbers! but no effects. :(
_equalizer.SampleFilters[9].AverageGainDB = 35.5;
Other channels works well (0-8).

I found what's wrong! I've got the solution :)
the problem was from the Equalizer Sample Source Code I've downloaded from CScore Codeplex Page
var source = CodecFactory.Instance.GetCodec(ofn.FileName)
.Loop()
.ChangeSampleRate(32000)
.AppendSource(Equalizer.Create10BandEqualizer, out _equalizer)
.ToWaveSource();
I commented the ".ChangeSampleRate" Part and it has been solved!
I changed it to:
source = CodecFactory.Instance.GetCodec(ofn.FileName)
.Loop()
.ChangeSampleRate(44100)
.AppendSource(Equalizer.Create10BandEqualizer, out _equalizer)
.ToWaveSource();

Play .oni-File on loop in C# / WPF

I'd like to play a previously recordet *.oni-File in C#/WPF. While, with the help of this tutorial I was able to get to RGB- and Depth-Stream to show up on my UI, I don't know how to play an *.oni-file.
The OpenNI page mentions, that I'd just have to "connect" to the file instead of the device, but I can't find the proper piece of code to do so.
The openni::Device class provides an interface to a single physical hardware device (via a driver). It can also provide an interface to a simulated hardware device via a recorded ONI file taken from a physical device.
If connecting to an ONI file instead of a physical device, it is only required that the ONI recording be available on the system running the application, and that the application have read access to this file.
I also found some clues / discussions, but none of it did help much
C# problem with .oni player
OpenNI-dev: Not able to play the skeletonRec.oni
EDIT: I found a way to at least get the recording played using the SamplesConfig.xml. I just inserted the following code into the <ProductionNodes>:
<Recording file="\test.oni" playbackSpeed="1.0"/>
Sadly, that recording crashes to program when it's done playing - I'm now looking for a way to loop the recording...
EDIT 2: Just if anybody should be interested, I'm using those lines to set the recording on loop:
ScriptNode scriptNode;
context = Context.CreateFromXmlFile(path + "\\" + configuration, out scriptNode);
Player p = (Player)context.FindExistingNode(NodeType.Player);
if (p!=null) p.SetRepeat(true); //Make sure it's really a recording.

If anybody should need the code one day - I managed to load the file and play the recording without the need of a config file:
Context context = new Context();
// Add license
License license = new License();
license.Vendor = "vendor";
license.Key = "key";
context.AddLicense(license);
// Open file
context.OpenFileRecordingEx("record.oni");
// Set to repeat
Player p = (Player)context.FindExistingNode(NodeType.Player);
if (p != null) p.SetRepeat(true);
