Hello, Accelerator types in Powershell are aliases for .NET types or classes.
Using them can shorten syntax, simplify it and gain performance.

# List accelerators types.
[PSObject].Assembly.GetType('System.Management.Automation.TypeAccelerators')::Get

## Some examples of use

# Generate an identifier
[PSCredential]::New("titi", (ConvertTo-SecureString 'P@ssword' -AsPlainText -Force))
# Equivalent to
$password = ConvertTo-SecureString 'P@ssword' -AsPlainText -Force
New-Object System.Management.Automation.PSCredential('titi', $password)

# Easy URL manipulation
$url = [uri]"https://www.altf4-formation.fr/powershell"
$url.host
$url.localpath

# Check an email, convert to type [mailaddress]
[mailaddress]"test@test.com"

# Check an IP address, convert to type [ipaddress} :
[IPAddress]'10.0.0.2'
# But we realise that it can also convert this value:
[IPAddress]'10.2'
# We can counter the problem as follows
$ip = '10.0.0.2'
($ip -as [IPAddress]).IPAddressToString -eq $ip
# "Equivalent" to the following regular expression:
"255.25.190.241" -match "^([01]?\d?\d\.|2[0-4]\d\.|25[0-5]\.){3}([01]?\d?\d|2[0-4]\d|25[0-5])$"

# Create a custom object
[PSCustomObject]@{Name='Guillaume';Age=25}
[PSObject]@{Name='Guillaume';Age=25}
# Equivalent to :
New-Object PSObject -property @{Name='Guillaume';Age=25}

# Define a duration (days, hours, minutes, seconds)
$duree = [TimeSpan]::New(2, 10, 30, 40)
# Equivalent to :
new-timespan -Days 2 -Hours 10 -Minutes 30 -Seconds 40

# Convert to date
[DateTime]::Parse('2021-10-12')
[DateTime]::Parse('12-10-2021')
[DateTime]::Parse('10-12-2021')
[DateTime]::Parse('10-12-2021',(get-culture))
[DateTime]::Parse('10-12-2021',[cultureinfo]::GetCultureInfo('en-us'))
[DateTime]::Parse('10-12-2021').ToString('yyyy_MM_dd')
[DateTime]::Parse('10-12-2021').AddDays(8)
[DateTime]::Parse('10-12-2021').AddDays(5).AddMonths(-3)
[DateTime]::now

## WMI
([WMICLASS]'Win32_Process').create("notepad.exe")
# Equivalent
(Get-WmiObject Win32_Process -List).create("notepad.exe")
# or
Get-CimClass -ClassName Win32_Process |
Invoke-CimMethod -MethodName create -Arguments @{CommandLine='notepad.exe'}

# WMI request to display the process with PID 0 :
[Wmi]"Win32_Process.Handle=0"

# Remote request:
[WmiClass]"\\remotecomputer\root\cimv2:Win32_Process"

# Use WQL (WMI Query Language) :
([WmiSearcher]"SELECT * FROM Win32_Process").Get()

# Create an accelerator type
$Accelerator = [PowerShell].Assembly.GetType("System.Management.Automation.TypeAccelerators")
# Add an accelerator type
$Accelerator::Add('resolve','System.Net.dns')
# Use the accelerator type
[resolve]::GetHostAddresses('www.google.fr')
