.NET 9.x OpenApi support#

Follow the basic instructions for OpenApi integration, then modify as follows:

Add packages to your project to support NSwag. The following packages are required:
- Microsoft.AspNetCore.OpenApi.
- CommunityToolkit.Datasync.Server.OpenApi.
Add the following to the top of your Program.cs file:
```
using CommunityToolkit.Datasync.Server.OpenApi;
```

Add a service to generate an OpenAPI definition to your Program.cs file:

builder.Services.AddOpenApi(options => options.AddDatasyncTransformers());

Enable the middleware for serving the generated JSON document and the Swagger UI, also in Program.cs:
```
app.MapOpenApi();
```
Decorate each table controller with the following attribute:
```
[ApiExplorerSettings(IgnoreApi = false)]
```

Browsing to the /openapi/v1.json endpoint of the web service allows you to download the API. The OpenAPI definition can then be imported into other services (such as Azure API Management).

Known issues#

The .NET 9.x OpenApi support currently does not support dynamic schema generation. This means that the schema generated within the OpenApi document will be incomplete.
