WebSharper Core


  • #921 Now JSON deserialization can handle the System.Object type, implemented as follows:
    • deserializing on the client side just returns the parsed value (ie. one of: null, a boolean, a string, a number, an array or a plain object).
    • deserializing on the server side produces a boxed value:
      • null, boolean, string return a value of the corresponding type.
      • number: returns a float (System.Double)
      • array: returns a recursively parsed obj[]
      • object: returns a recursively parsed Dictionary<string, obj>
    • serializing from System.Object is not supported. This is to avoid accidentally upcasting the argument of Json.Serialize to System.Object when a type annotation is missing.


  • #935 Seq.chunkBySize and other similar functions does not fail erroneously on some inputs.
  • #934 If for a website project, there is no "outputdir" in ws.config or WebSharperOutputDir in project properties or a web.config file in the project folder, an explicit error is given that the unpack output directory cannot be determined.

WebSharper UI


  • Add Router.InstallInto and Router.InstallHashInto, which are similar to Router.Install and Router.InstallHash respectively except that they take a Var<'EndPoint> as argument rather than creating and returning one.


  • #164 Remove click event handler on Doc.Checkbox, only keeping change, to avoid setting the Var twice.
  • #166 Add proxy for quotation-based .OnXyz(...) event handlers.
  • #167 Fix initial value of Var.Make whenever an initial value is available from the View.
  • #168 Add View.TryGet : View<'T> -> option<'T> which returns the current value of a View if available, or None if not (eg if a View.MapAsync hasn't returned yet).

Happy coding!


The process is the long policy for the part so you need to remove the went handler then you need to add the proxy for event handler ans many process and steps are there so you can get from https://printerchatsupport.co.uk/dell-printer-support/ for the solution.
