Getting this error with .Net 7.0

'Method 'DetermineServiceOperationEndpoint' in type 'Amazon.SQS.ExtendedClient.AmazonSQSExtendedClient' from assembly 'Amazon.SQS.ExtendedClient, Version=1.3.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.'

AWSSDK.Core, AWSSDK.S3 and AWSSDK.SQS all on latest nuget package.

hi - also having this error. thanks

[tri-bao]

also got it on AWSSDK.SQS version 3.7.300.54 (latest at the time of writting)

[port120]

hi - the solution is to remove the AWS SQS nuget package from your project - it's conflicting.

Hi, after upgrading our solutions to .NET 8.0 we are also facing this issue. Any plans to fix that soon?

[port120]

hi - check the solution i posted above

[MnichMateusz-pki]

Thanks for your suggestion but this is not a real solution.
In our case, SQS cannot be removed from the project, your fix is helping only in specific NuGet packages configuration (where only ExtendedClient is needed), not when SQS has to be used.
As the problem did not occur with older .NET versions (that btw will lose its support really soon), the fix should be provided by the library contributors, to make sure ExtendedClient is compatible with AWSSDK.SQS in NET 7 or .NET 8 projects.
