when I have a TargetFramwork in the httpRuntime tag in Web.config, pages with an asp:RequiredFieldValidator do not render properly.

<httpRuntime targetFramework="4.6" requestValidationMode="2.0"/>

    <ej:Tab ID="tabNewOrder" runat="server" HeaderPosition="Top" AllowKeyboardNavigation="True">
            <ej:TabItem ID="tabStart" Text="Start">
                    <ej:TabItem ID="tabOptions" Text="Finish">
                            <div class="form-group">
                                <div class="col-md-12">
                                    <div class="input-group">
                                        <ej:MaskEdit ID="txtPurchaseOrderNumber" runat="server" Width="300px" Height="40px" WatermarkText="PO Number" />
                                    <asp:RequiredFieldValidator ID="rfvPurchaseOrderNumber" runat="server" ValidationGroup="insOrder"
                                        ErrorMessage="*PO Number Required*" SetFocusOnError="true" ControlToValidate="txtPurchaseOrderNumber" Display="Dynamic"                                    CssClass="text-danger" />
                                    <asp:RegularExpressionValidator ID="revPurchaseOrderNumber" runat="server" ValidationGroup="insOrder"
                                        ValidationExpression="^([0-9a-zA-z.\-\'\s]{1,50})$" ErrorMessage="*Max length 50 - only numbers or alphabets.*"
                                        ControlToValidate="txtPurchaseOrderNumber" Display="Dynamic" CssClass="text-danger" />

I can remove the targetFramework from httpRuntime and then the control works, but that gives problems in other modules (like Owin.Security.Providers.LinkedIn that stops working).

Is there a workaround?
