Deserialize: Type not supported with WebSharper.exe when using Json
websharpercompilerjsonwebsharper.exe

I am trying to compile a library with only 1 file using WebSharper.exe. The file contains the following code:

namespace DeserializationIssue

open WebSharper
open WebSharper.UI.Next
open WebSharper.UI.Next.Html
open WebSharper.UI.Next.Client

[<JavaScript>]
module Client =
    
    type User = {
        id: string
        claims: string list
    }

    let main =
        Json.Deserialize<User>("")
        |> ignore

        h1 [text "hello world"]
        |> Doc.RunById "main"

And I am using the following command:

1

WebSharper.exe -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Collections.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Control.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Core.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Core.JavaScript.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.InterfaceGenerator.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.JavaScript.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.JQuery.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Main.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Sitelets.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper.UI.Next\lib\net40\WebSharper.UI.Next.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper.UI.Next\lib\net40\WebSharper.UI.Next.Templating.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Web.dll" DeserializationIssue.dll DeserializationIssue.dll

But it fails with:

1

System.Exception: DeserializationIssue.Client+User: Deserialize: Type not supported: DeserializationIssue.Client+User

Why isn't User type supported?

.

You have to pass -r DeserializationIssue.dll to the WebSharper compiler as Json.Deserialize<_> is implemented by a macro so the WS compiler needs a reference to the dll the concrete type is in.

There seem to be something different between the MSBuild + WebSharper Target and WebSharper.exe when using Json. It compiles and bundle fine using the MSBuild on VS but when using WebSharper.exe, it just refuses to compile to WebSharper prompting the same error.

Hi Istvan thanks for the reply, I just tried to reference the dll but it still yield the same result.

WebSharper.exe -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Collections.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Control.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Core.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Core.JavaScript.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.InterfaceGenerator.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.JavaScript.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.JQuery.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Main.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Sitelets.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper.UI.Next\lib\net40\WebSharper.UI.Next.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper.UI.Next\lib\net40\WebSharper.UI.Next.Templating.dll" -r "C:\Projects\DeserializationIssue\packages\WebSharper\lib\net40\WebSharper.Web.dll" -r DeserializationIssue.dll DeserializationIssue.dll Compiled_DeserializationIssue.dll

I've also tried to separate the User type in another fs file and compile it on its own (in a dll called domain). So I had 2 dlls: Domain.dll and Client.dll, even with a ref -r Domain.dll, I can't compile the Client it still yield:

1

System.Exception: DeserializationIssue.Domain+User: Deserialize: Type not supported: DeserializationIssue.Domain+User
