I'm having difficulty connecting to my Azure File Share

Question

I'm having difficulty connecting to my Azure File Share

KeithB 20

I have an Azure Storage Account with a File share that I can successfully access from a WIndows File Explorer. I want to download these files via a web page.

using Azure.Storage.Files.Shares;
using Azure.Storage.Files.Shares.Models;
using System.IO;

connectionString = "DefaultEndpointsProtocol=https;AccountName=MyStorageAccountName;AccountKey=MyAccountKey;EndpointSuffix=core.windows.net";
// Instantiate a ShareClient which will be used to create and manipulate the file share
ShareClient share = new ShareClient(connectionString, "/MyFileShareName");
.
.
.

I get:

System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Diagnostics.DiagnosticSource, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.'

I have:

copied the connection string from the portal,
checked the DNS Name resolution,
checked TCP conectivity (https://learn.microsoft.com/en-us/azure/storage/files/files-troubleshoot?tabs=powershell)

I'm guessing this will be due to a wrong configuration or permission but I can't find it!

@KeithB Thanks for posting your query on Microsoft Q&A.

6/12/2023: I found a similar post on Stack overflow which suggests adding required NuGet references: https://stackoverflow.com/a/42704058

Please try this and let me know the results.

UPDATE 6/13/2023: Customer shared that updating the NuGet reference - System.Diagnostics.DiagnosticSource to latest version resulted in resolving the issue.

I already had System.Net.Http. Another answer mentioned System.Diagnostics.DiagnosticSource. I updated that to the latest version and success!

Many thanks for your help.
