Creating an Reading Ledger Entries in Azure Confidential Ledger

In my previous article I gave an introduction to Azure Confidential Ledger. In this article I am trying to publish a .NET code sample. There is already an example in MSDN which is not working as expected. Therefore I tried to build one while exploring API.  

I have created a .Net 6.0 based console application and will be using the default Program.cs class. 

Following Nuget packages are required to be installed. 

First get the ledger Uri, Collection Id and a console input as a message to be published. 

Getting started with Azure Confidential Ledger

Azure Confidential Ledger is one of the most interesting Confidential Computing offering on Azure. It offers you the capability store data in a secure blockchain with private and public ledger type options. In the back of it, it uses blocks in blobs stored in Azure Storage Account. Data in transit is secured with TLS 1.3 and allowed via verified certificate users as well as Azure AD users. 

Currently you can have Administrator, Contributor and Reader access levels assigned via Azure RBAC. Confidential Ledger runs on Trusted Execution Environments (TEEs) of Azure Confidential Computing. All the administrators and cloud providers are kept outside a Trusted Computing Base and it prevents anyone having access.
