Lambda Annotations to support OData endpoints

[aberbegall]

I have a LambdaHttpMethod.Get function that returns a list of elements stored in an Entity Framework provider database and I would like to add support for OData 8 queries to that function (e.g. http://amazonaws.com/odata/elements?$select=name)

• First problem I got stuck with was how to add the odata route and EDM model

services.AddControllers().AddOData(options => options.AddRouteComponents("odata", GetEdmModel()))
or
services.AddMvcCore().AddControllersAsServices().AddOData(options => options.AddRouteComponents("odata", GetEdmModel()))

• and the second was how to enable OData options for each function

[EnableQuery(AllowedQueryOptions = AllowedQueryOptions.Select)])

Is this even feasible whit Lambda Annotations framework?

P.S: https://learn.microsoft.com/en-us/odata/webapi-8/getting-started?tabs=net60%2Cvisual-studio-2022%2Cvisual-studio

@aberbegall I do not see OData as one of the supported feature in Lambda Annotations Design doc. Given that how the Lambda uses source generators to generate boilerplate code, I don't think it's feasible with Lambda Annotations. CCing @normj for input.

@aberbegall what you are trying to do might work with the MinimalAPI and AddAWSLambdaHosting as all the OData extensions would be available, as the Lambda Hosting effectively just wraps the ASP Net Core middleware.
