+# GeneratorInConsumerSolution
+
+This solution contains two projects: Generator and Consumer.
+Generator contains the generator that is used by the Consumer.
+
+The sample generator creates a partial declaration of the
+`[GeneratedId]`-annotated type (class/struct) that contains
+an additional auto-property:
+
+```csharp
+    public System.Guid Id { get; } = System.Guid.NewGuid();
+```
+
+### Usage Note
+
+Please note that because [`Directory.Build.props`](./Directory.Build.props) by default uses `*` Version, NuGet will resolve that to the latest *stable* version. Most often is not what you want, so please replace that version with the one you want to test.
+
+Also, if you're validating your development with the sample, please remember that after NuGet once restores a version, it'll cache it in the default `packages` folder - to use new Package with the same version string, you'll need to delete cached packages from that folder.
