The call is ambiguous beetween the following methods or properties MVC, devexpress

I have a MVC project and I'm using devexpres 14.1.6. I defined devexpress scripts and stylesheets on _Layout.cshtml page as below

head =>

@Styles.Render("~/Content/css") @Styles.Render("~/Content/Bootstrap/css") @Scripts.Render("~/bundles/modernizr") @Scripts.Render("~/bundles/jquery") @Scripts.Render("~/bundles/bootstrap") @RenderSection("scripts", required: false) @Html.DevExpress().GetScripts( new Script { ExtensionSuite = ExtensionSuite.NavigationAndLayout }, new Script { ExtensionSuite = ExtensionSuite.HtmlEditor }, new Script { ExtensionSuite = ExtensionSuite.GridView }, new Script { ExtensionSuite = ExtensionSuite.PivotGrid }, new Script { ExtensionSuite = ExtensionSuite.Editors }, new Script { ExtensionSuite = ExtensionSuite.Chart }, new Script { ExtensionSuite = ExtensionSuite.Report }, new Script { ExtensionSuite = ExtensionSuite.Scheduler }, new Script { ExtensionSuite = ExtensionSuite.TreeList }

body =>

@Html.DevExpress().GetStyleSheets( new StyleSheet { ExtensionSuite = ExtensionSuite.NavigationAndLayout }, new StyleSheet { ExtensionSuite = ExtensionSuite.Editors }, new StyleSheet { ExtensionSuite = ExtensionSuite.HtmlEditor }, new StyleSheet { ExtensionSuite = ExtensionSuite.GridView }, new StyleSheet { ExtensionSuite = ExtensionSuite.PivotGrid }, new StyleSheet { ExtensionSuite = ExtensionSuite.Chart }, new StyleSheet { ExtensionSuite = ExtensionSuite.Report }, new StyleSheet { ExtensionSuite = ExtensionSuite.Scheduler }, new StyleSheet { ExtensionSuite = ExtensionSuite.TreeList } )

While my devexpress version is 14.1.3 my project was working perfectly but after I upgrated my devexpress version 14.1.3 to 14.1.6 I started recieve the following error =>

CS0121: The call is ambiguous between the following methods or properties: 'DevExpress.Web.Mvc.UI.HtmlHelperExtension.DevExpress(System.Web.Mvc.HtmlHelper)' and 'DevExpress.Web.Mvc.UI.HtmlHelperExtension.DevExpress(System.Web.Mvc.HtmlHelper)'

I cleaned Temporary ASP.NET Files but I recieved same error.


If you upgrade the DX version the old assemblies will not get removed from the bin directory.

Then the mentioned error will show up. Manually clean the directory ( VS does not know the old files anymore and probably will not delete them ).

<strong>Edit:</strong> This not only applies to DX assemblies but any assembly you might upgrade.
