ServicePointManager.ServerCertificateValidationCallback += 
  new RemoteCertificateValidationCallback(ValidateCertificate);

public static bool ValidateCertificate(object sender, X509Certificate cert, 
  X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
      return true;
}

Installed certificates expiring? Use X509KeyStorageFlags.PersistKeySet - What is the impact of PersistKeySet

Adding XML transforms to non-Web projects (Console, Winforms, WPF etc.)

1. Add Debug/Release versions of confit as XDT transforms
2. Add MSBuild.Microsoft.VisualStudio.Web.targets nuget PackageReference
3. Import targets (conditionally or it won’t load the first time)
4. Add TransformXml to AfterBuild

<Project>
    ...
      <ItemGroup>
        <None Include="App.config" />
        <None Include="App.Debug.config">
            <DependentUpon>App.config</DependentUpon>
            <SubType>Designer</SubType>
        </None>
        <None Include="App.Release.config">
            <DependentUpon>App.config</DependentUpon>
            <SubType>Designer</SubType>
        </None>
    </ItemGroup>
