Using Azure Powershell to start and stop a VM
Using an Azure VM is a convenient way to test new software without having to corrupt your own terminal or using more resources for a virtual instance using Virtual Box, VMWare, etc.
As you may already know if a VM is stopped there are no charges for computing cost. However you will still incur a charge for the storage used by the VM (which is significantly less). Using a powershell script to manage the state of these VMs are helpful. I have the shutdown powershell script on a scheduler that runs nightly.
In order to use azure powershell you must do the following:
- Install Azure PowerShell.
- Connect to your subscription within Azure Powershell
Fortunately Microsoft has documented this process in an article located at: http://azure.microsoft.com/en-us/documentation/articles/install-configure-powershell
After installing feel free to try the following code (make sure to replace “MY_COMPUTER” with the name of your VM:
Start-AzureVM -ServiceName "MY_COMPUTER" -Name "MY_COMPUTER" Stop-AzureVM -ServiceName "MY_COMPUTER" -Name "MY_COMPUTER" -Force
Generating a certificate and private key using openssl
Sometimes you need to generate a quick certificate to test your app. Using openssl you can easily accomplish this, take a look at my example below:
# Generate Cert and Key in seperate file # Provide the .cert to the end user openssl req -new -newkey rsa:1024 -days 365 -nodes -x509 -keyout QA.key -out QA.cert # Merge cert and private key to make a p12 file, this file will be used by .NET's X509Certificate2 class, The private key will be accessible via the "PrivateKey" property openssl pkcs12 -export -in qa.cert -inkey qa.key -out qa.p12 -name "QA"

Logging off WS-Federation by creating a wsignout1.0 message
Recently I integrated my web app with Azure ACS but was having a difficult time signing out of ACS (deleting my cookie off the
public ActionResult LogOff()
{
// Load Identity Configuration
FederationConfiguration config = FederatedAuthentication.FederationConfiguration;
// Get wtrealm from WsFederationConfiguation Section
string wtrealm = config.WsFederationConfiguration.Realm;
string wreply;
// Construct wreply value from wtrealm (This will be the return URL to your app)
wreply = wtrealm;
// Read the ACS Ws-Federation endpoint from web.Config
// something like "https://<your-namespace>.accesscontrol.windows.net/v2/wsfederation"
string wsFederationEndpoint = ConfigurationManager.AppSettings["ida:Issuer"];
SignOutRequestMessage signoutRequestMessage = new SignOutRequestMessage(new Uri(wsFederationEndpoint));
signoutRequestMessage.Parameters.Add("wreply", wreply);
signoutRequestMessage.Parameters.Add("wtrealm", wtrealm);
FederatedAuthentication.SessionAuthenticationModule.SignOut();
string signoutUrl = signoutRequestMessage.WriteQueryString();
return this.Redirect(signoutUrl);
}
