It looks like you are missing a using
statement:
Message: c:\inetpub\wwwroot\sc92sc.dev.local\Views\SimpleComponent\Title.cshtml(3): error CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'Sxa' and no extension method 'Sxa' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)
Make sure that either your Title.cshtml
has:
@using Sitecore.XA.Foundation.SitecoreExtentionsSitecoreExtensions
or that you have added that to your system.web.webPages.razor<namespaces>
namespaceselement in the /views/web.config
file:
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
