azure devops - Visual studio team services deploymen/buildt certificate error

Question

I am trying to build a click-once application using the Continuous integration and deployment feature in VSTS (Visual studio team services Online)We are trying to build this using the Hosted agent Visual studio 2015 We had difficulties signing the strong name key file with an error of

MSB3326: Cannot import the following key file: xxxx.snk. The key file may be password protected. To correct this, try to import the certificate again or import the certificate manually into the current user's personal certificate store. And after that

MSB3321: Importing key file "xxxx.pfx" was canceled.

I have tried to both select from store and from file changed the location and made sure to commit but with no success. Any ideas how i can overcome this errors or what am doing wrong.

Clerification on answer selected

Just wanted to make a clarification if anyone else has the same issue, in addition to the answer i had to place my certificate in my source control code and commit it. Then to select its location add a global variable on the VSTS Build

$cert.Import("$(CertPath)", $password, [System.Security.Cryptography.X509Certificates.X509KeyStorageFlags]"PersistKeySet") Where $(CertPath) would be something like $(Build.SourcesDirectory)SharedSolutionFilesCertificateName.pfx

Answer 1

You can create a PowerShell script and add a PowerShell Script step in your build definition to import the certificate file before the VSBuild step.

Build failed without PowerShell Import Certificate Step:

Build passed with PowerShell Import Certificate Step:

The PowerShell Script I used:

$pfxpath = 'pathtoees.pfx'
$password = 'password'

Add-Type -AssemblyName System.Security
$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
$cert.Import($pfxpath, $password, [System.Security.Cryptography.X509Certificates.X509KeyStorageFlags]"PersistKeySet")
$store = new-object system.security.cryptography.X509Certificates.X509Store -argumentlist "MY", CurrentUser
$store.Open([System.Security.Cryptography.X509Certificates.OpenFlags]"ReadWrite")
$store.Add($cert)
$store.Close()
