}

    Public Overrides Sub Validate(ByVal certificate As X509Certificate2)
        ' Check that there is a certificate.
        If certificate Is Nothing Then
            Throw New ArgumentNullException("certificate")
        End If

        ' Check that the certificate issuer matches the configured issuer
        If allowedIssuerName <> certificate.IssuerName.Name Then

Remarks

Override the Validate method to specify how the X.509 certificate is validated.

When the X.509 certificate that is passed into the certificate parameter does not pass validation, throw the SecurityTokenValidationException.
