Azure Blob Storage Emulator Error

Question

I am trying to write a test app that will allow me to access Azure Blob Storage. I am using VS2013 and have Azure SDK V2.2 installed. The Azure Storage Emulator is running. However, the location used by the storage emulator

C:\Users[UserName]\AppData\Local\dftmp\wadd

seems to be different to the location used in VS2013 IDE. I'm not sure where that location is. I can create a container and upload files using the VS2013 IDE, but I then don't see them in the Storage Emulator location, so I have assumed they are different.

More simportantly, the code below fails with a The remote server returned an error: (400) Bad Request. error when it executes the line:

blobContainer.CreateIfNotExists();

Any ideas what is going on and why I can't get this to work in VS2013 using the emulator? It works just fine if I substitute my actual Azure credentials and write the file to the Azure Storage. I really want to build this test solution and do some debugging before moving a solution completely onto Azure.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    // Storage Emulator credentials
    string connectionString = "UseDevelopmentStorage=true";
    string myContainer = "images";

    CloudStorageAccount cloudStorageAccount;
    CloudBlobClient blobClient;
    CloudBlobContainer blobContainer;
    BlobContainerPermissions containerPermissions;
    StorageCredentials storageCredentials;

    private void InitialiseBlobStorage()
    {
        cloudStorageAccount = CloudStorageAccount.Parse(connectionString);
        blobClient = cloudStorageAccount.CreateCloudBlobClient();
        blobContainer = blobClient.GetContainerReference(myContainer);
        blobContainer.CreateIfNotExists();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void button1_Click(object sender, EventArgs e)
    {
        InitialiseBlobStorage();

        // Add code to upload image here
    }
}
