    WebMatrix - IISExpress - Umbraco - System.Web.Util.AppSettings.get_MaxJsonDeserializerMembers

    Hi,

    I installed Umbraco via WebMatrix in Win 7/.net 4 but I have a problem in the admin page. I got an error 500 on the Ajax call: http://localhost:54003/umbraco/webservices/TreeClientService.asmx/GetInitAppTreeData.

    I have this error message:

    "Message":"Method not found:  Int32 System.Web.Util.AppSettings.get_MaxJsonDeserializerMembers()\u0027.","StackTrace":"   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.ThrowIfMaxJsonDeserializerMembersExceeded(Int32 count) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize

    I tried to modify the web.config by adding    

    <add key="aspnet:MaxJsonDeserializerMembers" value="2000000"/>
     <add key="aspnet:MaxHttpCollectionKeys" value="2000000" />

    but it still doesn't work...

    I don't know what to do.... please, help :)
