.Net: Bug: Unable to add the Microsoft.SemanticKernel NuGet package (version 1.31.0) to an Azure Function App targeting .NET 8

[MuraliM]

Describe the bug
When adding the Microsoft.SemanticKernel NuGet package (version 1.31.0) to an Azure Function App targeting .NET 8, the application fails to process the blob when its uploaded. Failing to load Azure.Core: Could not load file or assembly 'System.Memory.Data, Version=6.0.0.0

Function trigger

public class Function1
{
    [FunctionName("Function1")]
    public void Run([BlobTrigger("loandocuments/{name}", Connection = "AzureWebJobsStorage")]Stream myBlob, string name, ILogger log)
    {
        log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");

        
    }
}

Error

For detailed output, run func with --verbose flag.
[2024-12-01T18:40:41.485Z] An unhandled exception has occurred. Host is shutting down.
[2024-12-01T18:40:41.486Z] Azure.Core: Could not load file or assembly 'System.Memory.Data, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

Additional information
I have tried updating System.Memory.Data to version 8.0.0 as well to 9.0.0 and no luck..
I think the issue #5226 is still occuring with System.Memory.Data.
When I run dotnet list package --include-transitive

@MuraliM - thanks for trying this out. @markwallace-microsoft is going to take a look and see why this is not working.

Version 1.29.0 had a change in that reference and it doesn't work either:

• System.Memory.Data.1.0.2 -> System.Memory.Data.6.0.0.

Version 1.28.0 does work for me (.net 8).

@MuraliM Thanks for reporting this issue.

It looks like it's coming from Azure .NET SDK, since the only place where System.Memory.Data is directly referenced in Semantic Kernel is a unit test project (which I think we can remove at some point).

I also found a similar issue here: Azure/azure-sdk-for-net#47467

Could you please try to use these package versions and see if that works for you?

• Azure.Storage.Blobs 12.22.0
• Azure.Storage.Common 12.21.0
• Azure.Storage.Queues 12.20.0
• Azure.KeyVaults.Secrets 4.6.0

Thank you!

@MuraliM I created a PR to remove System.Memory.Data direct dependency from SK solution (#9970), but as I mentioned in previous comment, I think the issue is occurring on Azure .NET SDK side.

I'm going to close this issue, for more information please see my previous comment. Thanks!
