How to use XPO in ASP.NET MVC3 application (Razor)

Question Comments

how to convert this syntaks

@model IEnumerable<CustomerViewModel>
@Html.Partial("IndexPartial", Model);

into vb syntax ?

almost forget, because in VB source code, index.cshtml still in C#, not in VBHTML

Hi,

The code would be as follows:

[VB.NET]
@ModelType IEnumerable(Of CustomerViewModel)
@Html.Partial("IndexPartial", Model)

As for the example, we will correct the syntax as soon as possible.

It sure would be nice if you would upgrade your examples to the current version of MircoSoft and DevExpress products.  When I tried to run the Example from here in VS 2013 using MVC 4, it had to convert to the current version and then I had to play with references and I finally ended up with this stack dump:

Can you post an already migrated version so I don't have to waste more hours?
