Unable to load libgdiplus in Signal R web application with web sockets (Mac OS)

I downloaded this repository from GitHub and try to run it on my MacOS laptop. It uses Signal R and web sockets.
It builds, it starts, it works
But when I try to open web socket I get an error:
Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
An unhandled exception has occurred while executing the request.
System.TypeInitializationException: The type initializer for 'Gdip' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'libgdiplus' or one of its dependencies.

I did brew install mono-libgdiplus but it didn't help.
I'm new to C# and Microsoft frameworks so what else can I do? (MacOS Ventura, Apple M1)
Solved: System.Drawing is not supported on my MacOS, so the peaces of code where this library is using should not be executed.

While the project you played with was very well designed for cross platform, it was unfortunately developed before .NET 6 introduced an important breaking change, that System.Drawing related API is only supported on Windows.
Like you found out, commenting out the lines related to System.Drawing works. But if you want similar functionalities, you will have to rewrite that part with another drawing library. There are many such options out there if search engines are used.

An error has occurred during web site deployment in App Service Editor

I made some changes in the QnAMakerBasDialog.cs file, in trying to edit the default threshold. I did not change any other thing. When I tried deploying my changes at first, I was not getting the expected response and so I went back the editor to reverse my changes. It was at this point I started getting this error message.
I need help in reversing all changes if possible but most expecially in getting "test web chart" and all my channels working again.
Please see error message error:
kindly note that I tried this in the kudu console but still got the same error message

Surprisingly, I also encountered this problem. I also encountered this problem in Buid after modifying the Azure Bot code!
Even with this error, my build is successful

<SOLVED> Unity & MySQL | Scripts work in editor but not in build

I have created a simple Unity application that uses MySQL. The app works perfectly in the Unity Editor, however when I build it for PC Standalone or Android, it does not work.
After checking the log files, the following exception has been thrown
PlatformNotSupportedException: Operation is not supported on this platform.
at MySql.Data.MySqlClient.MySqlConfiguration..cctor () [0x00000] in <5bca8ad0d7cb4bf194403b342b8f0938>:0

How can MySQL not be supported on either of my platforms (both Android and PC Standalone) yet it works in Unity editor? Furthermore, I have recently created another game that also uses MySQL and works fine on all platforms. What could be the issue?
Feel free to ask me for code files, Unity files or whatever you think you need to help me solve the issue. Thank you!
Edit: Solved | just changed the API compatibility settings to .NET 4.x

I think this because of API Compatibility Level, here are the references to similar problems:

link 2
API Compatibility Level can be found in:

Can't build in batchmode on remote linux machine

I have an unusual problem when build on remote machine.
Target is Android and i try build application on remote server (Debian 3.16.7-ckt20-1+deb8u4, unity: unity-editor-5.3.5f1+20160525_amd64.deb).

It looks as if the sound card is not installed on the remote machine, but it was found there. Like the the video card, too.

I think I have tried everything, but the result remains the same.
On the local machine with a similar configuration everything works fine.
Had met anyone else with a similar problem and if so, how you solved it?

MdilXapCompile.exe -- Windows Phone Device Deployment Error

I'm trying to deploy my appo to my Lumia 930 so I can test it on something other than an emulator, but every time I hit F5 it basses the build but crashes on deplyment.
MIDLXapCompile log file:
CrossGen failed
Error processing assembly C:\Users\mrrey_000\Dropbox\Dev\Windows Store\AnimeWatcherXYZ EX Summer\AnimeWatcherXYZ.WindowsPhone\obj\ARM\Debug\MSIL\Microsoft.Advertising.Mobile.Display.winmd
Raw error code: 2148733978
I tried deleting the reference to the Microsoft Advertising SDK and applying i oce again, I've also tried to remove the previous version of the app from my device - didn't help.
And yeah, I'm deploying a DEBUG package, not RELEASE.
How can I fix this?
