Hi There,

Here is the error with stacktrace...

This occurred after upgrading to .NETCore 2.1

Perhaps related to #109
Try downgrading to .NET Core 2.0

[ComputerMaster1st]

Unable to downgrade due to another package I use breaks with 2.0.

EDIT: The sockets in 2.1 are needed for it to function.

[stefancreed37]

Create new project.

[Tyrrrz]

I have no idea why this happens but this is an issue that appears only on .NET Core 2.1 preview, afaik.

[ComputerMaster1st]

Allow me to rephrase that...

The package I use which can only work on 2.1 is Discord.Net (Discord changed voice infrastructure for one region and requires 2.1 to function correctly).

The problem with YE is found on HttpClientEx Line 35

[SlowLogicBoy]

This is not YE issue, this is an issue with new HttpClient on .Net Core 2.1 SDK preview which is not supported. If you can't downgrade to netstandard2.0 you could try reverting HttpClient to an old one. How to do this is written here: https://blogs.msdn.microsoft.com/dotnet/2018/04/11/announcing-net-core-2-1-preview-2/

[ComputerMaster1st]

Where should this "AppContext" code be written?

[ComputerMaster1st]

Sorted.

[Tyrrrz]

Can the issue be closed?

[ComputerMaster1st]

-Case Closed-

[jpprobr]

was this issue fixed ?

[ComputerMaster1st]

Hi There,

This issue has been fixed since NETCore 3 was released.
