AuthenticationContex missing AcquireToken method and CreateAuthorizationHeader

Question

I am trying to work with Azure AD.

This is the code I'm using:

Add-Type -Path      "D:\GraphAPI\Microsoft.IdentityModel.Clients.ActiveDirectory.2.14.201151115\lib\net45\Microsoft.IdentityModel.Clients.ActiveDirectory.dll" 


# Change these three values to your application and tenant settings
$clientID = "CLIENT ID for application"
$clientSecret = "KEY for application"
$tenant = "tenant domain name"

# Static values
$resAzureGraphAPI = "https://graph.windows.net";
$serviceRootURL = "https://graph.windows.net/$tenant"
$authString = "https://login.windows.net/$tenant";

# Creates a context for login.windows.net (Azure AD common authentication)
  [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext]$AuthContext = [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext]$authString

# Creates a credential from the client id and key
[Microsoft.IdentityModel.Clients.ActiveDirectory.ClientCredential]$clientCredential = New-Object -TypeName "Microsoft.IdentityModel.Clients.ActiveDirectory.ClientCredential"($clientID, $clientSecret)

# Requests a bearer token
$authenticationResult = $AuthContext.AcquireTokenAsync($resAzureGraphAPI,     $clientCredential);

# Output the token object
Write-Host -ForegroundColor Yellow "Token object:"
$authenticationResult | Format-List

# Example to get all users
Write-Host -ForegroundColor Yellow "Getting all users"
$users = Invoke-RestMethod -Method GET -Uri "$serviceRootURL/users?api-version=1.5" -Headers @{Authorization=$authenticationResult.CreateAuthorizationHeader()} -ContentType "application/json"
$users.value | Format-Table UserPrincipalName,DisplayName

But I have two errors

Method call failed because [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContex] does not contain a method named "AcquireToken

Method call failed because [Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContex] does not contain a method named CreateAuthorizationHeader

Can you help me solve these errors?

Thanks or your help
