In this link explain about  model  see a excerpt       model  lowercase  m   is a reserved keyword in Razor views to   declare the model type at the top of your view  You have put the   namespace too  e g    model MyNamespace Models MyModel      Later in the file  you can reference the attribute you want with    Model Attribute  uppercase  M

Before using  strongly type html helper into view  this line    Html TextBoxFor p   gt  p Product Name    You should include your model into you page for making strongly type view    model SampleModel

A common error that is the cause of this is when you add    Model SampleModel   at the top of the page instead of   model SampleModel

It seems to me that you have an untyped view  By default  Razor views in MVC3 RC are typed as dynamic  However  lambdas do not support dynamic members  You have to strongly type your model  At the top of your view file add   model SampleModel

Seems like your view is typed dynamic  Set the right type on the view and you ll see the error go away
