I'm attempting to create a strongly-typed view based on a class from another assembly. For whatever reason though, my Razor view doesn't seem to have any visibility of other assemblies referenced on my project. e.g.
@model MyClasses.MyModel results in the error in Visual Studio 2010, "The type or namespace name MyClasses could not be found (are you missing a using directive or an assembly reference?)."
The same class referenced in the standard view engine works fine. I have the same trouble trying to reference the class in the body of my view.
Am I missing something about Razor or do I need to reference the assembly some other way?

Right click the Index. cshtml file and select View in Browser. You can also right click the Index. cshtml file and select View in Page Inspector.
The @ symbol is used in Razor initiate code, and tell the compiler where to start interpreting code, instead of just return the contents of the file as text. Using a single character for this separation, results in cleaner, compact code which is easier to read.
You can add support for Pages to any ASP.NET Core MVC app by simply adding a Pages folder and adding Razor Pages files to this folder.
Razor Pages is sometimes described as implementing the MVVM (Model, View ViewModel) pattern. It doesn't. The MVVM pattern is applied to applications where the presentation and model share the same layer. It is popular in WPF, mobile application development, and some JavaScript libraries.
There is a new configuration section that is used to reference namespaces for Razor views.
Open the web.config file in your Views folder, and make sure it has the following:
<configuration> <configSections> <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" /> </sectionGroup> </configSections> <system.web.webPages.razor> <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <pages pageBaseType="System.Web.Mvc.WebViewPage"> <namespaces> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> <add namespace="SquishIt.Framework" /> <add namespace="Your.Namespace.Etc" /> </namespaces> </pages> </system.web.webPages.razor> </configuration> Alternatively, you can add using statements to your shared layout:
@using Your.Namespace.Etc; <!DOCTYPE html> <head> .... After editing the Web.config, restart Visual Studio to apply the changes.
