GetCustomAttributes fails to retrieve CmdletAttribute with ConfirmImpact property

Steps to reproduce

[System.Management.Automation.Cmdlet("Get", "Thing", ConfirmImpact = 'High', SupportsPaging = $true)]class C2{}
$t = [C2].GetCustomAttributes($false)
$t

From Scripting.Classes.Basic.Parsing.Tests.ps1

Expected behavior

NounName                : Thing
VerbName                : Get
DefaultParameterSetName :
SupportsShouldProcess   : False
SupportsPaging          : True
SupportsTransactions    : False
ConfirmImpact           : High
HelpUri                 :
RemotingCapability      : PowerShell
TypeId                  : System.Management.Automation.CmdletAttribute

Actual behavior

Exception calling "GetCustomAttributes" with "1" argument(s): "'ConfirmImpact' property specified was not found."
At line:1 char:9
+         $t = [C2].GetCustomAttributes($false)

Repros

This issue has something to do with the new ALC model. I have brought up this to CoreCLR team.

This is a reflection bug in CoreCLR. It has been reported to CoreCLR team.

SandeepSutari I think we need to move this issue to future. This is a reflection bug in CoreCLR and it won't be fixed in the near future.

Fixed via PR #2472

This was caused by a bug in AssemblyLoadContext -- dynamic assemblies are not correctly associated with the right load context. This has been fixed in the .NET Core preview packages for Nov. release (1.1.0).

Now it works fine:
