The base class includes the field 'report', but its type (Microsoft.Reporting.WebForms.ReportViewer) is

I'm desperate. I have this page with a report viewer that worked until a couple of days ago. I haven't changed my webconfig or anything else, but I am getting this error now. Here's my ASP.NET code:

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="RisultatoStampaPdf.aspx.cs" Inherits="Fatture.Pagine.StampaDocumenti.RisultatoStampaPdf" %>

<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="BodyContent" runat="server">

I've found an answer that seems to make sense:

Try to add the reference: Microsoft.Reporting.WebForms and afterward, if you get another error try to compare between <%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0 and the version that is written in the reference you added, if there is a difference change the version to the version of the Microsoft.ReportViewer.WebForms.

hope it'll help. here is a link: https://mohamedelkassas.wordpress.com/2014/04/21/the-base-class-includes-the-field-xxx-but-its-type-microsoft-reporting-webforms-reportviewer-is-not-compatible-with-the-type-of-control-microsoft-reporting-webforms-reportviewer/

and another one with another solution: http://snahta.blogspot.co.il/2012/01/microsoftreportingwebformsreportviewer.html
