The Type JavaScriptSerializer is not defined RRS feed

  • Question

  • Hi,

    in my ASPX-page I'm importing the Namespace:

    Imports System.Web.Script.Serialization

    and then try to use the class:

    Dim Jsonconvert As New JavaScriptSerializer
    On my test server this causes no Problems, but on my production Server I get an error, stating that the type JavaScriptSerializer is not defined.

    Does anyone know how to fix this?

  • Hi,

    Please try to check that you have added the following to your project:

        using System.Web;
        using System.Web.Script;
        using System.Web.Script.Serialization;

    Here is a similar thread, hope it can give your some idea:

  • Thanks for your suggestions. Unfortunately none of it helped. When I changed my project to target .NET Framework 4, I still couldn't add Version 4.0 of System.Web.Extension, because the System said that I have already referenced it. Explicitly removing it first doesn't seem to be possible either. And I still cannot comprehend why it works without problems on our testing server, as both machines seem to be configured identically.
