+- ** Trying to use the AspNetCore gRPC fails to build ([WPF/810](https://github.com/dotnet/wpf/issues/810))**
+
+ Trying to use a gRPC service in a WPF app, `<UseWPF>true</UseWPF>`, results in a build error. Visual Studio and VSCode does not report the problem in intellisense but it appears when doing a `dotnet build .sln`.
+ 
+ **Actual behavior:** <!-- callstack for crashes / exceptions -->
+Results in a 
+```
+error CS0246: The type or namespace name 'Greet' could not be found (are you missing a using directive or an assembly reference?)
+```
+
+As a workaround the client gRPC portion can be split into a separate project and it will build correctly.
