.Net: Could not load file or assembly Microsoft.Bcl.AsyncInterfaces exception

[WeihanLi]

Describe the bug

Could not load file or assembly Microsoft.Bcl.AsyncInterfaces exception when using the redis memory storage

To Reproduce

var apiEndpoint = Guard.NotNullOrEmpty(Environment.GetEnvironmentVariable("AZURE_OPENAI_API_ENDPOINT"));
var apiKey = Guard.NotNullOrEmpty(Environment.GetEnvironmentVariable("AZURE_OPENAI_API_KEY"));
var kernelBuilder = new KernelBuilder();
kernelBuilder.WithAzureChatCompletionService("gpt-35-turbo", apiEndpoint, apiKey);
kernelBuilder.WithAzureTextEmbeddingGenerationService("text-embedding-ada-002", apiEndpoint, apiKey);
// kernelBuilder.WithMemoryStorage(new VolatileMemoryStore());
kernelBuilder.WithMemoryStorage(new RedisMemoryStore("localhost:6379"));
var kernel = kernelBuilder.Build();
var collectionName = "Products";
await using var fs = File.OpenRead("text-sample.json");
var list = await JsonSerializer.DeserializeAsync<Product[]>(fs);
Guard.NotNull(list);
foreach (var product in list)
{
    await kernel.Memory.SaveInformationAsync(collectionName, product.Description, product.Title, product.Description, product.Category);
}


file sealed class Product
{
    [JsonPropertyName("id")]
    public required string Id { get; set; }
    
    [JsonPropertyName("category")]
    public required string Category { get; set; }
    
    [JsonPropertyName("title")]
    public required string Title { get; set; }
    
    [JsonPropertyName("content")]
    public required string Description { get; set; }
}

Running on a console targeted at net8.0 and with .NET 8 RC1 SDK

Expected behavior

success without exception

Additional context

Without exception when using the memory storage such as VolatileMemoryStore

workaround solution: add a reference for Microsoft.Bcl.AsyncInterfaces
