Fiddler API does not support values set to oSession["ui-hide"] in the extension

I am creating a Fiddler extension in which users will have the ability to filter the sessions in the session list. Based on the user's filter condition I want to show/hide/highlight the sessions in the Fiddler's session list. But the problem that I am facing right now is that oSession["-hide"] = true.ToString().ToLower(); does not make that session hidden. Also now I am not sure how can I highlight that session in the session list.

Problem with CertMaker

I'm coding a very basic C# Console application to try FiddleCore.

I start the application and then I navigate with the browser to http://www.telerik.com/forums and some output is printed on the console.

Here is the code:

01.using System;

02.using System.Collections.Generic;

03.using System.Linq;

04.using System.Text;

05.using System.Threading.Tasks;

06.using Fiddler;

07.

08.namespace TestFiddler

09.{

10. class Program

11. {

12. static void Main(string[] args)

13. {

14. Console.WriteLine("Start...");

15. FiddlerApplication.OnNotification += delegate(object sender, NotificationEventArgs oNEA) { Console.WriteLine("** NotifyUser: " + oNEA.NotifyString); };

16. FiddlerApplication.Log.OnLogString += delegate(object sender, LogEventArgs oLEA) { Console.WriteLine("** LogString: " + oLEA.LogString); };

17. FiddlerApplication.AfterSessionComplete += delegate(Fiddler.Session oS)

18. {

19. Console.WriteLine("Finished session:\t" + oS.fullUrl);

20. };

21.

22. FiddlerApplication.Startup(8888, FiddlerCoreStartupFlags.Default);

23.

24. Console.ReadKey();

25. Console.WriteLine("Shutting down...");

26. FiddlerApplication.Shutdown();

27. Console.ReadKey();

28. }

29. }

30.}

I have a problem with CertMaker but I don't understand why. I have already copied CertMaker.dll in the Debug folder but I'm obviously making a mistake somewhere.

Here are first few lines of output:

CryptographicException

Hello,

Sorry if this has already been solved, but a bit of Googling hasn't turned up anything that works.

I'm trying to inspect communications between a client application on my PC and a web server on my office network. Running Fiddler v5.0.20182.28034.

When I click Tools>Options>HTTPS>Decrypt HTTPS Traffic, I get this exception:

System.Security.Cryptography.CryptographicException: Access is denied.

at System.Security.Cryptography.X509Certificates.X509Store.Open(OpenFlags flags)
at ..(String ) in C:\JenkinsHome\jobs\FiddlerReleaseBuild\workspace\Fiddler2\Common\Core\DefaultCertProvider.cs:line 1147
at ..(String , Boolean ) in C:\JenkinsHome\jobs\FiddlerReleaseBuild\workspace\Fiddler2\Common\Core\DefaultCertProvider.cs:line 1260
...

There's more information, in the file attached.

If I click Actions>Reset All Certificates, I get a similar but different exception:
