.net - Publishing from Visual Studio 2015 - allow untrusted certificates

Question

I am publishing my ASP.NET 5 MVC6 project from Visual Studio 2015. I have imported publish profile from my server. Connection validates successfully, however when I publish my project I have the following error:

ERROR_CERTIFICATE_VALIDATION_FAILED

Connected to the remote computer ("XXXXXXXXX") using the specified process ("Web Management Service"), but could not verify the server's certificate. If you trust the server, connect again and allow untrusted certificates.

There is no option to allow untrusted certificates in publishing settings.

Answer 1

The option to allow untrusted certificates is not yet supported in the current tooling. Hopefully, this gets updated very soon. You can, however, set it manually.

1. Open the publish profile file (.pubxml) inside /Properties/PublishProfiles in a text editor
2. Inside the <PropertyGroup> element, set AllowUntrustedCertificate to True (<AllowUntrustedCertificate>True</AllowUntrustedCertificate>) or add it if it doesn't exist
3. Set UsePowerShell to False (<UsePowerShell>False</UsePowerShell>).

At this time of writing, the generated powershell script disregards the AllowUntrustedCertificate property which is probably a bug, hence, the need to set it to False.

You can get powershell to work if you update the module version in the .ps1 file.

As a side note, you can also get around this problem by "trusting" the server's certificate locally.
