I have been unable to locate an effective solution for setting the default audio input/output device. Could you kindly share your approach to resolving this issue?
I attempted to find a solution, however, all the information I uncovered appeared to be outdated and not compatible with .NET 7.

I am new in SIP Programming, while searching on Google "voip sdk c# open source github", I got reference of sipsorcery. I had downloaded it and try to play with samples but I am unable to execute it. I had search tutorials on google and youtube but I can't found any.
https://github.com/sipsorcery/sipsorcery
Please someone guide if I have to implement sipsorcery (Video and Audio Call) then How can I setup Server, which support to multiple client.
Thanks in advance,
Best way to get started are the example applications:
Get Started Audio,
Get Started Video you will need something to call such as MicroSIP.
All the examples are .NET Core or Framework applications and can be generally be executed from the command line with dotnet run. If you have problems with them, or the library, I'd recommend the asking on the GitHub Issues page.
Also note that the sipsorcery project is library not a Server application. It can be used to build server applications but the only ones available in the repo are examples.
I managed to download audio file from a remote source, and I want to change it's metadata, like Author, Title, Album.
I save it locally so it's easily accessible and editable, but I can't find anything to edit it's metadata.
I've tried:
Android.Media.MediaMetadataEditor but the error is pretty straightforward:
This class is obsoleted in this android platform
I'm using latest SDK (28) and API, for android Pie. And it is also stated on android developer documentation
This class was deprecated in API level 21.
Use MediaMetadata instead together with MediaSession.
I really searched for some example, and I didn't found anything useful, most of cases are with playlist.
I don't get how MediaSession can replace in any manner the MediaMetadataEditor, since MediaSession
Allows interaction with media controllers, volume keys, media buttons, and transport controls.
A MediaSession should be created when an app wants to publish media playback information or handle media keys
Instead MediaMetadata seems what I need because
Contains metadata about an item, such as the title, artist, etc.
And its Builder class is promising.
I'm sure that just reading that pages I should be able to understand how to do it, but after hours of trying, it seems I'm not experienced enough to learn from that documentation.
Is there an example to understand it?
Thanks
I found a solution outside android Library.
taglib-sharp seems working on android project, and it can be installed via nuget package, the name is TagLibSharp
Really easy to use:
TagLib.File my_file = TagLib.File.Create(path_to_my_file);
string[] performers = new string[1]{"My Performer"}
my_file.Tag.Title = "The real title";
my_file.Tag.Performers = performers;
my_file.Save();
Easy.
I’m new to Cloud9 and I’m facing some issues.
I’m attempting to run the C# code on the IDE and am failing to do so, I think I know why but I cant seem to be able to resolve the issue.
The picture uploaded below should have everything needed to solve the problem
enter image description here
Upon further research, I found a link that goes through a step by step process on how to install .NET core. However, I'm having issues, with setting the project template using this code for the terminal dotnet new console -lang C#
It starts decompressing then stops at 99%. (as indicated in image below) The first error that pops up states that System.IO.IOException: No space left on device not sure what to do with this though.

I kept on attempting the same code and it has managed to complete the decompressing stage only to start resetting again at the Expanding stage. (Refer to image below).

Run C# is not yet supported on Cloud9 IDE
https://docs.c9.io/docs/supported-languages
I think #shingo is correct to say C# is not supported BY DEFAULT. It is possible, however, to make it happen as shown in the links below, but not advisable as there is little help out there. I wouldn't do it if I were you.

Recently stumbled upon this post whilst trying to decide on the best way of getting a VLC player into C#.
Does VLC media player have a C# interface?
I downloaded the dll files and imported them into my project, but then realised I had no real idea of how to use them. Has anyone got a Windows Forms example of this code that works? The code have tried is shown below -
Vlc.DotNet.Core.Medias.MediaBase media = new
Vlc.DotNet.Core.Medias.PathMedia(#"C:\Users\...\SampleVideos\Wildlife.wmv");
Vlc.DotNet.Forms.VlcControl vlcControl1 = new Vlc.DotNet.Forms.VlcControl();
vlcControl1.Play(media);
I am also using the code in this link in the main program.cs of my project.
http://vlcdotnet.codeplex.com/wikipage?title=Forms
The current problem I experience is that upon starting the project it throws a NullReferenceException when it gets to ->
vlcControl1.Play(media)
The problem seems to be with the vlcControl but I am unsure why. The documentation seems to rather thin and I couldn't find any working examples on the codeplex site. If anyone has a working forms example or knows what I might have missed please let me know!
Here is the call stack present when the error occurs ->
RTSPViewer_Test.exe!RTSPViewer_Test.Form1.Form1_Load(object sender,
System.EventArgs e) Line 31 + 0xd bytes C#
RTSPViewer_Test.exe!RTSPViewer_Test.Program.Main() Line 30 + 0x1d bytes C#
When debugging it appears that the Media and Medias attribute of the VLC control are both null. When trying to set the Media of the control to the media object created above a
NullReferenceException
Checking the VLC control object Media does indeed equal null, but I am not sure why it hasn't been initialised properly.
I was unable to get the program to work using the latest version of the Vlc.dotnet libraries but instead used the alpha 2 version which was posted by Raj. I used VLC version 1.1.5 with this library to get the basic example to function properly. My end objective was to stream from an rtsp device, however this library does not appear to support this functionality yet.
For anyone looking to use a good C# wrapper for using VLC then this is a great example -
http://www.codeproject.com/Articles/109639/nVLC
Used the library files from VLC 1.1.1 with this project and works fine. Supports pretty much all the features that you would usually use in VLC but gives you much more control over what you use them for.
Many of the issues that arise when using these DLL wrappers arose from incorrect versions of the source DLL files. The VLC libraries are only 32 bit at this time, so you need to make sure to compile using x86 mode otherwise the libvlc.dll will not load properly and the application will crash. Using the above example you must also make sure that the libvlc.dll, libvlccore.dll and the plugins folder are included in the build folder.
Reposting from http://www.mentalis.org/forum/thread.qpx/971 because I need an answer. I hope you guys can help me out.
The component in question is Org.Mentalis.SecurityServices.dll.
Hey all. I'm having troubles.
CryptographicException: Couldn't acquire crypto service provider context.
StackTrace:
at Org.Mentalis.SecurityServices.Cryptography.CryptoHandle.CreateInternalHandle(IntPtr handle, String container)
at ORG.Mentalis.SecurityServices.Cryptography.CryptoHandle.get_Handle()
at Org.Mentalis.SecurityServices.Cryptography.RC4CryptoServiceProvider.ctor()
at <place in my app where I try to create the RC4 CryptoServiceProvider>
I had to copy that exception trace by hand, from a screenshot sent to me by a client.
Essentially, I have created a .NET 3.5 WinForms application for XP that uses the RC4CryptoServiceProvider to load encrypted user details from an .ini file on startup. It's worked fine for months.
About a week ago, I got this exact exception message on my computer. I did some hunting online, but couldn't find much - everything I found was related to websites.
I eventually stumbled on a workaround that got things working on my computer. When I deleted the files from the following three folders:
C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys\
C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\token\
C:\Documents and Settings\my_username\Application Data\Microsoft\Crypto\RSA\token\
The problem went away. The folders re-populated with new information the next time I ran the application.
I had thought this was just something unique to my own development environment - that I had downloaded something weird that corrupted my cryptographic files and folders. It's not a field in which I am an expert - I just use the component, and it Just Works. Well... Up until now.
The problem is, one of my company's clients has just recently started experiencing the same error, and I'm not comfortable asking them to just clear out their Crypto files without being able to justify why. Also, it would seem that this wasn't due to something odd that I downloaded, as this exception is arising on a series of commercial Terminal Servers.
I've been looking around for support on this issue, but I'm not having much luck. I'll keep looking around. Can anyone out there shed some light on the situation?
Thanks for your time.
Do you know if your clients have the CSPs installed on their computer? Older versions of Windows won't have certain CSPs installed. It's also possible that they're running a foreign version of Windows that doesn't support strong cryptography (I'm thinking the French version might not be allowed to have all of them.)
Another possibility might be permissions. Maybe the process running the code is no longer running with administrative authority, or the authority associated with your account changed.
The Mentalis library should really be setting the CRYPT_VERIFYCONTEXT flag when calling CryptAcquireContext. Since they are not, each instance of RC4CryptoServiceProvider creates a handle to the default persistent key container (which is stored in the file you located with procmon).
Are you creating keys in multiple threads (or from multiple processes)? A wild guess would be that you are having some problems with locking of the file.
