Method not found: Azure.Response`1 Azure.Storage.Files.Shares.ShareDirectoryClient.Exists

As the microsoft announcement of Migration from deprecated libraries – WindowsAzure.Storage and Microsoft.Azure.Storage to Azure.Storage.Blobs , I was instructed to migrate old Azure File Share logic to use the new library, BUT I encountered a weird runtime exception saying 'Method not found: 'Azure.Response`1<Boolean> Azure.Storage.Files.Shares.ShareDirectoryClient.Exists(System.Threading.CancellationToken)'

My X++ code below:

using Azure.Storage;
using Azure.Storage.Files.Shares;
using Azure.Storage.Files.Shares.Models;
using System.Collections;
using System.Threading;

class AzureFile
{
...

public void existsFolder(Filename _FilePath)
{
ShareClient shareClient = new ShareClient(connectionString,fileShareReference);
ShareDirectoryClient rootDir = shareClient.GetRootDirectoryClient();
ShareDirectoryClient fileDir = rootDir.GetSubdirectoryClient(_FilePath);

if (!fileDir.Exists(CancellationToken::None))
{
error(fileDir.Uri.ToString());
}
}
...
}

As I know in C#, it doesn't need to pass any parameter, but X++ says it doesn't support literal of CancellationToken, is this the problem?

By the way, the version of my dev environment is PU64(10.0.40), the corresponding Azure.Storage.Files.Shares.dll is 12.12.1.0, the corresponding Azure.core.dll 1.35.0

I also check the loaded assembly with reflection code below, it shows the method did exist.....

assembly = Assembly::Load(assemblyName);
var version = assembly.GetName().Version;
Info("Azure.Storage.Files.Shares Version:" + version.ToString());

System.Type type = assembly.GetType("Azure.Storage.Files.Shares.ShareDirectoryClient");
System.Reflection.MethodInfo methodInfo = type.GetMethod("Exists");
if (methodInfo != null)
{
info("Return type: " + methodInfo.ReturnType.ToString());

ParameterInfo[] parameters = methodInfo.GetParameters();
int i, paramCount;
paramCount = parameters.Length;

for (i = 1; i <= paramCount; i++)
{
ParameterInfo parameter = methodInfo.GetParameters().Get(i - 1);
info(strFmt("Parameter %1: %2", i, parameter.ParameterType.ToString()));
}
}
else
{
info("Method 'Exists' not found.");
}
