This repository holds the F# code that implements the Microsoft Orleans quickstart example UrlShortener:

• Quickstart: Build your first Orleans app with ASP.NET Core

Notice that for now, it's necessary to have part of the project in C#, so Orleans correctly generates code. There's more information at the following links:

• DejanMilicic/OrleansFsharp
• Issue :: F# host: Could not find an implementation for interface OrleansDashboard.IDashboardGrain - C# host ok
• Q&A :: How to use Orleans in a single F# script file .fsx?

How to run?

    # start the server
    dotnet run --project Server/
    # assert that the HTTP server started at the port 5062

Then, at the browser, open the server endpoint that shortens another URL, like:

• http://localhost:5062/shorten?url=https://gaio.dev

This endpoint outputs a new URL, like http://localhost:5062/go/4F09B02C, which, once you open must redirect you to the previously shortened URL, in this case: https://gaio.dev.
