# Run a PowerShell script after a Visual Studio build

Microsoft’s docs are lacking on the simple how-to stuff, so I’m going to make a contribution here. This took too long for me to figure out, but I was helped by this Stack Overflow post.

If you want to simply execute a PowerShell script after a build in Visual Studio, here’s how. I’m using Visual Studio 2013.

### Step 1: Find your PowerShell executable

You will need to know this information later, so open a PowerShell command line and simply type $PSHOME to print out the contents of that environment variable. PS>$PSHOME
C:\Windows\System32\WindowsPowerShell\v1.0


Note that C:\Windows\System32\WindowsPowerShell\v1.0 is the location of the powershell.exe executable. It might be different on your machine.

### Step 2: Open the Build Events dialog for your Project

Visual Studio organizes build events at the project level, not the solution level. Navigate to your custom build events like this:

• Open Visual Studio and right click on your project.
• Click Properties
• Click the Build Events tab

You will see two big text boxes, Pre-build event command line and Post-build event command line. For new projects these should be empty. I wanted to run a script after my build, so I will type into the latter.

### Step 3: Add your script to the build event command line

In the big empty text box, add the command of the following format (be sure to use those quotes):

"C:\Path\to\powershell.exe" -file "C:\Other\path\to\custom-script.ps1"


The first half is the path to powershell.exe you located earlier. Then, you have the -file argument, and finally your custom script. For me, the specific command was:

"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -file "C:\Tools\load-fetcher-tools.ps1"


Hope that helps!
