Unable to generate both a public client and model together

[markphillips100]

Describe the issue or request
I'm attempting to generate a C# client and typed model for the Azure Maps Creator data plane, spec tag package-2023-03-preview. To obtain a model I have always used (and is suggested in a few issues here) generation1-convenience-client: true, and to obtain a public client that uses that model I also use public-clients: true.

It seems that with the latest autorest and autorest/csharp it is not possible to use both flags set to true. So I either get a model with no public client, or no model and a public client that has no knowledge of a model, i.e. all method return types are non-generic Response type.

I've no idea when this change occurred as it's been over a year since I last attempted a generation.

Describe your ideas for solutions
Support creation of a typed public client with a typed model for the data plane please.

Info:
autorest: 3.7.1
autorest/csharp: 3.0.0-beta.20240511.1

Forgot to mention the original autorest/csharp version that worked for me was 3.0.0-beta.20230111.3.
