Running full ASP.NET Core Web API in the isolated worker

With the isolated worker being the preferred (and in future) [only option](https://techcommunity.microsoft.com/t5/apps-on-azure-blog/net-on-azure-functions-roadmap/ba-p/2197916) to run Azure Functions with .NET, I think it would make sense to investigate the ability to run full ASP.NET Core in the isolated worker. This could make a lot of APIs easier to migrate to Functions.

A sample which achieves this - https://hajekj-func-aspnetcore.azurewebsites.net/ ([source](https://github.com/hajekj/az-functions-aspnetcore)) which uses [NL.Serverless.AspNetCore](https://github.com/tntwist/NL.Serverless.AspNetCore) package works quite fine, there are just some setup caveats and the use of multiple projects isn't ideal.

Lambda allows you to run full [ASP.NET Core within](https://github.com/aws/aws-lambda-dotnet/tree/master/Libraries/src/Amazon.Lambda.AspNetCoreServer) and the hosting model seems actually quite similar.

Is this something planned or worth looking into?
