Multithreaded Selenium Bot does not work correctly

I wrote a bot in C#, I used Selenium.
Problem: When I start more threads at same time, the bot does the work in the first window. All of the e-mail addresses are being added to the "E-mail" textbox in the same window instead of one e-mail address per window.
But it should look like:
Start function: DivisionStart()
private void DivisionStart() {
foreach(var account in BotConfig.AccountList) {
while (CurrentBotThreads >= BotConfig.MaxLoginsAtSameTime) {
Thread.Sleep(1000);
}
StartedBotThreads++;
CurrentBotThreads++;
int startIndex = (StartedBotThreads * BotConfig.AdsPerAccount + 1) - BotConfig.AdsPerAccount - 1;
int stopIndex = BotConfig.AdsPerAccount * CurrentBotThreads;
if (stopIndex > BotConfig.ProductList.Count) {
stopIndex = BotConfig.ProductList.Count;
}
Debug.Print("Thread: " + StartedBotThreads);
var adList = GetAdListBy(startIndex, stopIndex);
foreach(var ad in adList) {
Debug.Print("Für thread: " + StartedBotThreads + " | Anzeige: " + ad.AdTitle);
}
Debug.Print("Parallel");
var ebayBotThread = new Thread(() => {
var botOptions = new IBotOptionsModel() {

StartPageUrl = "https://www.ebay-kleinanzeigen.de/m-einloggen.html?targetUrl=/",
EbayLoginEmail = account.AccountEmail,
EbayLoginPassword = account.AccountPassword,
Ads = adList,
};
var ebayBot = new EbayBot(this, botOptions);
ebayBot.Start(StartedBotThreads);
Thread.Sleep(5000);

}
If I remove the Thread.Sleep(5000); in the DivisionStart function it will work, but I need it I actually want to wait for a found proxy but I simulated it with Thread.Sleep
How can I solve my problem?
Thanks for any answer!

I fixed it.
I used UndetectedChromeDriver wich does not use different ports.
I use another Undetected driver now.
Thank you all

Extent reports 4.0.3 - capture screenshot not working - c#, specflow

I am trying to add screenshot capture to extent report. I am able to capture screenshot using selenium webdriver but attaching screenshot to extent report is not working.
Code in [AfterStep] hook will actually generate step for failure in report. I have not included the code for pass step.
step.AddScreenCaptureFromPath(screenshotPath)
code runs successfully but the cannot find the attachment in report.
This is Hooks code trying to generate report for BDD feature.
//Global Variable for Extend report
private static ExtentTest featureName;
private static ExtentTest scenario;
private static ExtentTest step;
private static ExtentReports extent;
//Initialize extent reports
[BeforeTestRun]
public static void InitializeReport()
{
//initialize extent report before test starts
string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
var htmlReporter = new ExtentHtmlReporter(assemblyFolder + "\\Reports\\ExtentReport.html");
htmlReporter.Config.Theme = AventStack.ExtentReports.Reporter.Configuration.Theme.Dark;
//Attach report to reporter
extent = new ExtentReports();
extent.AttachReporter(htmlReporter);
}
//generate feature name dynamically
[BeforeFeature]
public static void BeforeFeature()
{
//Create dynamic feature name
featureName = extent.CreateTest<Feature>(FeatureContext.Current.FeatureInfo.Title);
}
//generate scenario name dynamically
[BeforeScenario]
public void Initialize()
{
//Create dynamic scenario name
scenario = featureName.CreateNode<Scenario>(ScenarioContext.Current.ScenarioInfo.Title);
}
//get the screenshot upon failure
[AfterStep]
public void InsertReportingSteps()
{
var stepType = ScenarioStepContext.Current.StepInfo.StepDefinitionType.ToString();
PropertyInfo pInfo = typeof(ScenarioContext).GetProperty("ScenarioExecutionStatus", BindingFlags.Instance | BindingFlags.Public);
MethodInfo getter = pInfo.GetGetMethod(nonPublic: true);
object TestResult = getter.Invoke(ScenarioContext.Current, null);
if (ScenarioContext.Current.TestError != null)
{
if (stepType == "Given"){
step = scenario.CreateNode<Given>(stepType + " " + ScenarioStepContext.Current.StepInfo.Text).Fail(ScenarioContext.Current.TestError.Message);
}
else if (stepType == "When"){
step = scenario.CreateNode<When>(stepType + " " + ScenarioStepContext.Current.StepInfo.Text).Fail(ScenarioContext.Current.TestError.Message);
}
else if (stepType == "Then"){
step = scenario.CreateNode<Then>(stepType + " " + ScenarioStepContext.Current.StepInfo.Text).Fail(ScenarioContext.Current.TestError.Message);
}
string screenshotPath = CaptureScreenshot.Capture(driver);
//Capture screenshot not attaching screenshot to extent reports
step.AddScreenCaptureFromPath(screenshotPath);
}
}
//flush extent reports
[AfterTestRun]
public static void TearDownReport()
{
//Flush report once test completes
extent.Flush();
}
class CaptureScreenshot
{
public static string Capture(IWebDriver driver)
{
ITakesScreenshot ts = (ITakesScreenshot)driver;
Screenshot screenshot = ts.GetScreenshot();
string screenShotName = "screenShotName_" + Calendar.getCurrentDate();
string assemblyFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
string finalpth = assemblyFolder + "\\Reports\\Screenshots\\";
string screenshotDir = finalpth + screenShotName + ".png";
string localpath = new Uri(screenshotDir).LocalPath;
screenshot.SaveAsFile(localpath);
return localpath;
}
}

I was able to resolve the issue by using MediaEntityBuilder
https://extentreports.com/docs/versions/4/java/
MediaModelProvider mediaModel =
MediaEntityBuilder.createScreenCaptureFromPath("screenshot.png").build();
test.fail("details", mediaModel);
// or:
test.fail("details",
MediaEntityBuilder.createScreenCaptureFromPath("screenshot.png").build());
You'll need to include the screenshot in your step
step = scenario.CreateNode<Then>(stepType + " " + ScenarioStepContext.Current.StepInfo.Text).Fail(ScenarioContext.Current.TestError.Message,MediaEntityBuilder.CreateScreenCaptureFromPath(screenshotPath).Build());

Cortana Background task crashes on mobile but works perfectly on desktop

Been looking at this for the past few days now and I'm no closer to a solution. The code below is based on the CortanaVoiceCommand sample at https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CortanaVoiceCommand and the code works perfectly on desktop but the background task is crashing on mobile each time.
In OnTaskCanceled the BackgroundTaskCancellationReason always reports as SystemPolicy but I'm no closer to finding a solution.
Appreciate any help anyone can suggest.

how to use application/x-rtp binding with gstreamer-sharp?

I am wondering how/if it's possible to use the follwing gstreamer bindings using gstreamer-sharp/C# for Windows?
udpsrc port=1234 ! application/x-rtp, payload=127 ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink
I am not sure how to do the "application/x-rtp, payload=127" part and I think that's all I am missing, but I am not 100% sure about this. The videosink I am trying to use is dshowvideosink.

application/x-rtp, payload=127 is just the GstCaps for the udpsrc element. You can listen on the pad-added signal and add the caps once a pad is created.
new Caps("application/x-rtp, payload=(int)127");

ProcessEvent not called in TFS plugin

Recently i have decided to create a plugin for the TFS for tracking work item changes based on ISubscriber interface.
So the workflow would be the following:
1) Work item state changes
2) Plugin catches the WorkItemChangedEvent
3) Send an email to the person specified in the Requester
As the base for my project, i used the following project from CodePlex - The Mail Alert
After i adopted it to my needs and saved compiled binaries in %TFS-DIR%\Microsoft Team Foundation Server 14.0\Application Tier\Web Services\bin\Plugins the TFS restarted the tier and... that's it. On work item change the ProcessEvent method is not called, but it should be.

No errors or exceptions are thrown in the Event Log either. Tracing TFS (trace=true property in web.config) also was of no help.
Maybe someone could help or shed light on this mysterious case?
UPDATE:
Thanks for a reply Giulio Vian!
Here how it goes:
1) I haven't seen the dependencies broken, plus the constructor WorkItemChangedEventHandler is successfully called. That is seen in the Windows Event Log - WorkItemChangedEvent Started message is written.
2) I am not sure how to register the event handler.... i'll look that up
3) I am not sure how this works. I thought just copy-pasting dlls in the appropriate folder will do the trick, and there is no need for an account for the plugin. Mind giving a bit more info on this?
4) yes. Web.config in the main Web config in Application Tier\Web Services
5) Yes. Using an account with Administer rights. if i set a break point in the constructor, it is reached. Any other place in the code is not reached.

Many things can be wrong.
If any dependency is broken, you should see an error in the Event log
If you do not register the "WorkItemChangedEventHandler" event source, no message is written
Can the user account running the plugin access TFS?
How did you enabled the tracing (you pasted a bunch of code, but no configuration)?
Have you attached the debugger to the TFS process and set a breakpoint (do not this on a production TFS)?
