couldn't create a log file using AzureAppendBlobAppender

[saiseisei]

I use a web.config contain the log4net configuration.
but I check the blob container, and it has nothing yet.
I was searching the idea for a long time as a beginner.
and I don't know why.

web.config

var repo = log4net.LogManager.CreateRepository(Assembly.GetEntryAssembly(), typeof(log4net.Repository.Hierarchy.Hierarchy));
XmlNodeList elemList = XmlDoc.GetElementsByTagName("log4net");
log4net.Config.XmlConfigurator.Configure(repo, (XmlElement)elemList[0]);

ILog Logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
if(Logger.IsDebugEnabled)
{
    Logger.Debug(" ---- All is well !");
}

As the ConsoleAppender is working well , the BlobAppender works nothing .
My Azure Storage Explorer has no file created.
Are there Any ideas for me .

The latest repos is using outdated and deprecated versions of nuget packages that have been and replaced..

NOTE: As of version 9.4.0, this library has been split into multiple parts and replaced: See https://www.nuget.org/packages/Microsoft.Azure.Storage.Blob/, https://www.nuget.org/packages/Microsoft.Azure.Storage.File/, https://www.nuget.org/packages/Microsoft.Azure.Storage.Queue/, and https://www.nuget.org/packages/Microsoft.Azure.Storage.Common/.
For table support, see https://www.nuget.org/packages/Microsoft.Azure.CosmosDB.Table/.
This client library enables working with the Microsoft Azure storage services which include the blob and file service for storing binary and text data, the table service for storing structured non-relational data, and the queue service for storing messages that may be accessed by a client.
For this release see notes - https://github.com/Azure/azure-storage-net/blob/master/README.md and https://github.com/Azure/azure-storage-net/blob/master/changelog.txt
