It seems like Net Standard 2.0 is included in the Unity API Compatability Layer. Does following the instructions here https://docs.unity3d.com/Manual/dotnetProfileSupport.html resolve this bug?

ArnCarveris commented 7 months ago

Nope, that was in AWSSDK.Core AWSConfig::GetConfig method, bc in net45 version gets config from System.Configuration.ConfigurationManager::get_AppSettings but it throws exception, but for netstandard2.0 it just returns hardcoded null, also it could be nice with targets had consistent API, bc non async method for netstandard2.0 became internal and that broke whole plugin bc many of code was relaying on that.

I came across a similar issue discussed here: https://github.com/aws/amazon-gamelift-plugin-unity/issues/67. It appears that IL2CPP does not support System.Configuration.ConfigurationManager, and the successful resolution involved using the AWS .NET SDK's netstandard2.0 DLLs from NuGet packages instead. Does the instructions provided in this guide https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/unity-special.html help in resolving the bug?
