@FarhanIshfaq Good morning. Please refer AmbiguousMatchException; the AmbiguousMatchException is thrown when a member is invoked late-bound and multiple overloads satisfy the binding criteria, or when more than one member matches the binding criteria passed to a reflection method that can return only a single result. Please check your project file if it's attempting to load multiple assemblies containing similar type definition for Android target.

Also refer Special considerations for Unity support for guidance on how to use AWSSDK assemblies in your Unity application.

I found an article on Unity forums Why do I get Error: Ambiguous Match Found (Non-Mediation PSR in use)? providing resolution for similar issue, if that helps.

Thanks,
Ashish

Hi Ashish how are you? i already did check all guidance about unity and aws but not anything is working if use .net standart 2.1 dll's then they just make auth with cognito but i can't make dataset to amazon cognito to sync user data with amazon cognito because in these dll's there is no class reference for saving the data on cognito Please share a guide if you can . i also did check the aws unity sdk which is 4 year's old. Thanks. Regards On Fri, Dec 6, 2024 at 11:09 PM Farhan Ishfaq ***@***.***> wrote:

they just make auth with
cognito but i can't make dataset to amazon cognito to sync user data with
amazon cognito because in these dll's there is no class reference for
saving the data on cognito

@FarhanIshfaq Good morning. Could you please elaborate your scenario? Looks like the original issue is resolved by using NET Standard 2.1 DLLs. what are you trying to sync with Cognito? And which class reference are you looking for? Have you tried using AWSSDK.CognitoSync DLL included in https://sdk-for-net.amazonwebservices.com/latest/v3/aws-sdk-netstandard2.0.zip?

Thanks,
Ashish

Yes i did use these sdk too but i didn't find CognitoSync.SyncManger file reference can you please guide a little how i can sync data on amazon cognito using these sdk on.

Thanks for the reponse.
