VisualStudio.com cannot load temporary UWP certificate during build

Question

I set up my Team Team Visual Studio account to clone my private GitHub repo and create a Windows UWP application anytime I queued up for the build. Cloning works without any problems; compilation of each project (6) works, except for one. UWP application project for Windows.

I get the following warnings when the build server compiles the application:

This is the last project of 6 to compile. After receiving warnings, he proceeds to copy all the output files to the final / bin directory. Then, when all this is done, he will send the same messages as above, but like errors this time he will not complete the assembly.

If I simply delete the certificate (as I did in this particular error log), it fails because it cannot find it. If I generate a certificate using the manifest editor in VS and assign it a password, the build server will fail because it does not know the password. Therefore, I cannot force it to create whether I provide a temporary test certificate or not.

How should we run UWP Windows 10 applications through the Team Team Visual Studio build system? This is what Microsoft has been encouraging for a while, so I suggested that it could be done. I can't seem to build a UWP project.

Answer 1

You can create a certificate without a password.

Or, add a PowerShell step to the assembly definition to import the password-protected certificate. The following is a powershell script option that you can use:

$pfxpath = 'myapp_TemporaryKey.pfx' $password = 'yourpassword' 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() 

Remember to set the "Working Folder" to the path where your pfx file is located.

Answer 2

By default .gitignore ignores any *.pfx file. Therefore, it is not added to git. I had the same problem that there is no *_StoreKey.pfx file on the build machine, so the build failed.

For me, the solution was to install *_StoreKey.pfx on the build server. Then creating the solution on the build server will succeed.
