  • Walkthrough: Creating an Asynchronous HTTP Handler

    The Microsoft tutorial Walkthrough: Creating an Asynchronous HTTP Handler did not describe how to use IHttpAsyncHandler from F#.
    It was also a bit complicated, because it did not show how to do it from Visual Studio. Here is the Visual Studio F# version. 1. Create empty ASP.NET Web Application. Call it FSharpHttpAsyncHandler. 2. Add a F# library project to the solution. Call it FSharpHttpAsyncHandler.Lib. 3. Add the following code to Library1.fs in FSharpHttpAsyncHandler.Lib 4. Add a reference to System.Web in FSharpHttpAsyncHandler.Lib 5. Add a reference to FSharpHttpAsyncHandler.Lib in FSharpHttpAsyncHandler. 6. Add the following to Web.config in FSharpHttpAsyncHandler. 7. In the Web tab of the project properties of FSharpHttpAsyncHandler, set Start url to http://localhost://whatever.SampleAsync 8. Run debug.

    Translation of the Azure Cosmos DB Graph-get-started sample project (https://github.com/Azure-Samples/azure-cosmos-db-graph-dotnet-getting-started/tree/master/GraphGetStarted) A Cosmos DB account must first be created e.g. via the Azure Portal & from these the endpoint & authorization key are retrieved. Given these, the script creates: (i) Document Client (ii) Database (iii) Graph (aka Document Collection). From Gremlin expressions (strings) the command CreateGremlinQuery creates queries (IDocumentQueries) that can be executed to read from or modify the graph.

  • Composing a list of functions

    Composition of functions in F# is easily achieved by using the >> operator. You can also chain an arbitary amount of functions (represented as a list or sequence) together by folding the list/seq with >>. [More formally: the set of endomorphisms 'a -> 'a forms a monoid with the binary, associative operator ">>" (or "<<") and the neutral element "id".]

  • Continuation-Passing Mnemonics

    Continuations provide a means whereby heap space can be traded for stack depth (heap space being generally more plentiful than stack depth). They are especially useful where tail recursion is not possible. Here are a couple of simple continuation examples that can be extended to cover more complex scenarios.
