Microsoft Team Foundation Server Best Practices Analyzer Doesn’t Play Nice With PowerShell 3.0

12 Nov 2014, by Sonny Nguyen in Developer

Today, I was tasked with getting TFSBPA to work on our TFS servers. We needed to analyze our repositories to see if what we’re doing is considered to be “best practice.”

After a quick search, I arrived at: http://msdn.microsoft.com/en-us/library/ee248630(v=vs.100).aspx

Installing was a breeze. However, in order to get the PowerShell Cmdlets, you have to do an advanced install and select it. It’s unchecked for whatever reason.

 

Alright! I have a new toy. Let’s fire it up and see get it to run. I start a scan.

Scan Type:          Team Foundation Server Complete Health Check

Server URL:        I select my TFS directory. Go.

Scan, scan, and scan. Five second scan completed. Wow, that was fast. Let’s see what’s going on.

Cannot validate the URL provided.
The scan was generated using the corrected URL “%TFSServerURLValidated%”.

WHAT?

After verifying my server URL. I have ruled out that this is just a bad error message.

Now what?

Oh look, Other Reports.

 

Exception in TFS PowerShell Object Processor:

System.Management.Automation.PSArgumentException

Incorrect Windows PowerShell version 3.0. Windows PowerShell version 2.0 is supported in the current console.
at System.Management.Automation.Runspaces.MshConsoleInfo.AddPSSnapIn(String mshSnapInID)
at System.Management.Automation.Runspaces.RunspaceConfigForSingleShell.DoAddPSSnapIn(String name, PSSnapInException& warning)
at Microsoft.TeamFoundation.Diagnostics.PowerShellObjectProcessor.EnsureInitialized(String scriptRoot)
at Microsoft.TeamFoundation.Diagnostics.PowerShellObjectProcessor.ProcessObject()

System.Management.Automation
Script

 

I see—we have PowerShell 3.0 installed, but it only likes 2.0. No problem!

A simple solution, we must navigate to our BPA install directory:

Mine was default: C:\Program Files (x86)\Microsoft Team Foundation Server 2013 Power Tools\Best Practices Analyzer

 

Create a new file: TfsBpa.exe.Config

The contents of this config file is as follows:

<?xml version ="1.0"?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0.30319"/>
    </startup>
</configuration>

 

This will allow for our BPA to use the Common Language Runtime, CLR4, to be used.

Restart BPA if it’s open, then run another scan. Make sure your server URL is set because it’s unset every time you start the application.
