+//   This code file has automatically been added by the "Nullable" NuGet package (https://www.nuget.org/packages/Nullable).
+//   Please see https://github.com/manuelroemer/Nullable for more information.
+//
+//   IMPORTANT:
+//   DO NOT DELETE THIS FILE if you are using a "packages.config" file to manage your NuGet references.
+//   Consider migrating to PackageReferences instead:
+//   https://docs.microsoft.com/en-us/nuget/consume-packages/migrate-packages-config-to-package-reference
+//   Migrating brings the following benefits:
+//   * The "Nullable" folder and the nullable "*Attribute.cs" files don't appear in your project.
+//   * The added files are immutable and can therefore not be modified by coincidence.
+//   * Updating/Uninstalling the package will work flawlessly.
