The makecert.exe utility, which is included in the Windows SDK
- It is sometimes included in Visual Studio installations (depending on the selections made during installation). A search of your machine for makecert.exe would provide verification that the Windows SDK was installed.
- If the Windows SDK was not installed, you may download it here
- You can learn more about the makecert.exe utility here
PowerShell with Azure Active Directory Module
- To download the latest PowerShell version see this page
- Install the Azure AD PowerShell Module, if it is not already installed in your client machine.

TODO: Other Prerequisites

Run this sample

Create an application account in Azure AD for your service.
- Sign in to the Azure management portal.
- Click on Azure Active Directory in the left hand navigation
- Click the directory tenant where you wish to register the sample application. This must be the same directory that is associated with your database (the server hosting your database).
- Click the Applications tab
- In the drawer, click Add.
- Click "Add an application my organization is developing".
- Enter mytokentest as a friendly name for the application, select "Web Application and/or Web API", and click next.
- Assuming this application is a daemon/service and not a web application, it doesn't have a sign-in URL or app ID URI. For these two fields, enter http://mytokentest
- While still in the Azure portal, click the Configure tab of your application.
- Find the Client ID value and copy it into a text editor, you will need this later when configuring your application ( i.e. a4bbfe26-dbaa-4fec-8ef5-223d229f647d /see the snapshot below/)
Logon to your Azure SQL Server’s user database as an Azure AD admin and using a T-SQL command provision a contained database user for your application principal:
```
CREATE USER [mytokentest] FROM EXTERNAL PROVIDER
```
- See this link for more details on how to create an Azure Ad admin and a contained database user.
On the machine you are going to run the project on, generate and install a self-signed certificate.
- To complete this step, you will need to use Makecert.exe
- Open a command prompt window
- Navigate to a folder where you want to generate a certificate file ( such as the folder where the demo files are) and change the following command for your environment
```
<Windows SDK Path>\makecert.exe -r -pe -n "CN=Cert_name" -ss My -len 2048 Cert_name.cer
```
for example, like so:
```
c:/"Program Files (x86)/Windows Kits/8.1/bin/x64"/makecert -r -pe -n "CN=mytokentestCert" -ss My -len 2048 mytokentestCert.cer
```

Add the certificate as a key for the application you created in Azure AD.

Click the Microsoft Azure Active Directory Module for Windows PowerShell shortcut on desktop to open a Windows PowerShell workspace that has the Azure AD cmdlets.
Copy the following code snippet to a text editor.

connect-msolservice

$cer = New-Object System.Security.Cryptography.X509Certificates.X509Certificate
$cer.Import("<full path>\Cert_name.cer")
$binCert = $cer.GetRawCertData()
$credValue = [System.Convert]::ToBase64String($binCert);
New-MsolServicePrincipalCredential -AppPrincipalId "<client id>" -Type asymmetric -Value $credValue -Usage verify

 + Replace <full path> with the path to your certificate and Cert_name with your Certificate name that you used in step 3 above. 
 + Replace <client id> with the client ID you copied in step 1.  
 + Copy and paste your snippet into the powershell window and run it.

The following command will verify that you added the certificate to your application's Active Directory Registration Get-MsolServicePrincipalCredential –ServicePrincipalName "URL"-ReturnKeyValues 0

Configure the certificate and your application account in the app.config file in the project.
- In Visual Studio, open app.config in the Solution Explorer
  - Find the app key ida:Tenant and replace the value with your AAD tenant name (your AAD domain)
  - Find the app key ida:ClientID and replace the value with the Client ID for the application registration from the Azure Portal (the value from step 1).
  - Find the app key ida:Cert_Name and replace the value with the subject name (CN) of the self-signed certificate you created
  - For example:
```
<add key="ida:Tenant" value="cqclinic.onmicrosoft.com" />   //this is the AAD domain
	<add key="ida:ClientId" value="a4bbfe26-dbaa-4fec-8ef5-223d229f647d"/>  //this is the Client ID
	<add key="ida:CertName" value="CN=mytokentestCert"/> //this is the Cert_name use by makecert.exe
```
- In Visual Studio, open Program.cs in the Solution Explorer
  - Make the following changes:
```
    builder["Data Source"] = "aad-managed-demo.database.windows.net"; // replace with your server name
    builder["Initial Catalog"] = "demo"; // replace with your database name
```
Run the demo. (Click Run or press F5)
- A successful authorization should result in a message that states "Connected to the database" similar to the following:
