How dispose connections to services such as Azure Storage - azure

Question

My function stores data up Azure Data Lakta Storage Gen 1.
But I got bug An error occurred while sending the request.
When I investigated,I knowed that my connection in azure function overcome 8k then it's broken.
Here is my code(Append to file Azure DataLakeStorage Gen 1)
//This for authorizing azure data lake storage gen 1
await InitADLInfo(adlsAccountName);
DataLakeStoreFileSystemManagementClient _adlsFileSystemClient;
//Here is my code to append data lake storage gen 1
using (var stream = new MemoryStream(Encoding.UTF8.GetBytes(buffer)))
{
await _adlsFileSystemClient.FileSystem.AppendAsync(_adlsAccountName, path, stream);
}
How to dispose that when every append ends.
I try to dispose
_adlsFileSystemClient.Dispose();
But it didn't dispose anything.My connection will up.

I read this
https://www.troyhunt.com/breaking-azure-functions-with-too-many-connections/1
and I have made connection down.Just use DO NOT create a new client with every function invocation.
Example Code :
// Create a single, static HttpClient
private static HttpClient httpClient = new HttpClient();
public static async Task Run(string input)
{
var response = await httpClient.GetAsync("http://example.com");
// Rest of function
}
