Viewstate error when using asp.net form 4.5 template forms authentication
using the asp.net 4.5 template from VS 2013 with forms authentication.
The standard template works fine. But when I insert this code in the asp.net file Site.Master
Code:
<asp:ContentPlaceHolder runat="server" ID="HeaderContent"/>
</head>
<body>
<form runat="server">
<ext:ResourceManager ID="ResourceManager1" runat="server" > </ext:ResourceManager>
<asp:ScriptManager runat="server">
<Scripts>
<%--To learn more about bundling scripts in ScriptManager see http://go.microsoft.com/fwlink/?LinkID=301884 --%>
<%--Framework Scripts--%>
<asp:ScriptReference Name="MsAjaxBundle" />
<asp:ScriptReference Name="jquery" />
when try logging in or logout. This will set the property
Page.ViewStateUserKey = _antiXsrfTokenValue; "from the template code behind in site.master in method page_init
and it will fail with
Code:
Server Error in '/' Application.

[HttpException (0x80004005): The state
I have tried the different combinations on the Ext:ResourceManager like DisableViewState="true" EnableViewState="false" . I believe the Ext is not supposed to tamper with the viewstate, so this error makes no sense ?
