function New-DbaXESession {
    <#
    .SYNOPSIS
        Creates a new XESession object - for the dogged.
 
    .DESCRIPTION
        Creates a new XESession object - for the dogged (very manual, Import-DbaXESession is recommended). See the following for more info:
 
        https://docs.microsoft.com/en-us/sql/relational-databases/extended-events/use-the-powershell-provider-for-extended-events
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances. You must have sysadmin access and server version must be SQL Server version 2008 or higher.
 
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
    .PARAMETER Name
        The Name of the session to be created.
 
    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
 
    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
