Write the C# code to implement the functionality of the mobile application.

[project-oagent-gh-app[bot]]

This is a complex task and may be divided into multiple parts. However, a sample C# code for a mobile application following some of these guidelines would look like this:

We need to create a bash script that will create the necessary files. Here is how you can do it:

#!/bin/bash

# Create the C# files
echo "Creating C# files..."

cat > Program.cs << EOF
using System;
using System.Diagnostics;
using System.Threading.Tasks;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;

namespace AzureBlobStorageApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Trace.WriteLine("Entering Main Method");

            try
            {
                // Connect to blob storage
                CloudStorageAccount storageAccount = CloudStorageAccount.Parse("<your-connection-string>");
                // Create a blob client for interacting with the blob service.
                CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
                // Get reference to the blob container
                CloudBlobContainer container = blobClient.GetContainerReference("<your-container-name>");

                // Fetch an image (or other content) from Blob Storage
                CloudBlockBlob blockBlob = container.GetBlockBlobReference("<your-blob-name>");
                using (var fileStream = System.IO.File.OpenWrite(@"<file-path>"))
                {
                    blockBlob.DownloadToStreamAsync(fileStream);
                }

                // Perform database operations (using optimized queries, indexes, etc.)

                // More application code here
            }
            catch (Exception e)
            {
                Trace.TraceError("Exception in Main Method: {0}", e);
            }
            finally
            {
                Trace.WriteLine("Exiting Main Method");
            }
        }
    }
}
EOF

echo "C# files created."

In this code, we are creating a simple C# application that connects to Azure Blob Storage and downloads a blob. We are using diagnostic tracing to record the flow of control and any exceptions that occur. We can scale this code and add more features according to the guidelines. Note that you will need to replace "", "", "", and "" with your actual Azure Blob Storage details and the file path where you want to download the blob.

We are also using async methods to improve performance. We are not implementing client-side caching, SQL query optimization, data denormalization, and other guidelines in this code due to size constraints. Those would be separate, often complex, tasks.

Remember that this bash script should be run in a bash shell, and it will create a file named Program.cs in the current directory. If you are on Windows, you can use Git Bash, Cygwin, or the Windows Subsystem for Linux.

Could you provide only the c# code?

[project-oagent-gh-app[bot]]

The C# code that implements the functionality of the mobile application, considering the architectural guidelines, would like this:

using System;
using Microsoft.Azure.Storage;
using Microsoft.Azure.Storage.Blob;

namespace AzureBlobStorageApp
{
    class Program
    {
        static void Main(string[] args)
        {
            // Connect to blob storage
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse("<your-connection-string>");
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

            // Get reference to the blob container
            CloudBlobContainer container = blobClient.GetContainerReference("<your-container-name>");

            // Fetch an image (or other content) from Blob Storage
            CloudBlockBlob blockBlob = container.GetBlockBlobReference("<your-blob-name>");

            // Create a snapshot of the blob
            var blobSnapshot = blockBlob.CreateSnapshot();

            // Use AzCopy to copy the blobs to another storage account
            Process.Start("AzCopy", "/Source:<source> /Dest:<dest> /SourceKey:<source-key> /DestKey:<dest-key> /Pattern:<pattern>");

            // More application code here
        }
    }
}

In this code, we create a snapshot of a blob and use AzCopy to copy the blob to another storage account. Please replace <your-connection-string>, <your-container-name>, <your-blob-name>, <source>, <dest>, <source-key>, <dest-key>, and <pattern> with your actual data.

Note: AzCopy is a command-line utility for copying data to/from Azure Blob storage and File storage. It needs to be installed and accessible from the command line. Also, it doesn't run in the same process as your C# application, hence we are using Process.Start() to start a new process that runs AzCopy.

This is a basic demonstration. In a real application, you may want to handle errors, check the status of AzCopy operation, and perform more complex tasks.
