+# Take your PowerShell to the next level with error handling and debugging
+
+There are a lot of great features for debugging PowerShell withing VSCode. And if you're like me.... you never use them....
+
+Let's change that today. I've made it my goal this year to be better and more consistent with how I debug my code and handle errors in my scripts.
+
+In this session, we're going to explore how errors are surfaced in PowerShell and how to handle those errors responsibly. We will also dive into using the debugger in VSCode to step through some PowerShell code to identify the potential sources of our errors.

+# From Script to Tool: Building Robust, Meaningful Tools with PowerShell
+
+I have been asked the same question many times over the years and it usually goes something like this: “How do I know when to do something through the command line, a script, a function or a module for something in PowerShell?”
+
+The short answer, is “YES”. But the deeper question is, “What kind of Tool are you trying to build?”
+
+When we think of “Tools”, they can come in all sorts of shapes, sizes and uses. PowerShell tools are no different and there are usually no wrong answers here.
+
+In this session, we will explore the evolution of building tools in PowerShell. From trial and error at the command line, to crafting a complete module. I will use some examples from my own experience when it comes to creating re-usable tools with our favorite scripting language and we will watch how a small one liner can evolve into a tool that you and your colleagues can’t remember how you lived without.

+
+<#
+.SYNOPSIS
+Manage Summit services remotely (get, start, stop, restart).
+
+.DESCRIPTION
+This script provides small wrapper functions to get and control a named Windows
+service on a remote computer using `Invoke-Command`. It exposes a simple
+parameterized interface at the top-level so it can be used interactively or
+as part of automation.
+
+.PARAMETER ComputerName
+The target computer where the service is running. Accepts DNS name or IP.
+
+.PARAMETER ServiceName
+The name of the Windows service to manage (as used by `Get-Service`).
+
+.PARAMETER Action
+The action to perform. Valid values are: `Get`, `Start`, `Stop`, `Restart`.
+
+.PARAMETER Credential
+A PSCredential object used for remote connections where alternate
+credentials are required.
+
+.EXAMPLE
+PS> .\3-Functions-1.ps1 -ComputerName srv01 -ServiceName "Spooler" -Action Get
+
+.EXAMPLE
+PS> .\3-Functions-1.ps1 -ComputerName srv01 -ServiceName "Spooler" -Action Stop

+
+.PARAMETER ComputerName
+The target computer where the service is hosted.
+
+.PARAMETER ServiceName
+The name of the service to act on.
+
+.PARAMETER Action
+The action to perform. Valid values are `Get`, `Start`, `Stop`, `Restart`.
