In the MVC 3 book by Steven Sanderson on p185 at the bottom, the following expression is used to render the paging links.
@Html.PageLinks(Model.Paginginfo, x=> Url.Action("List", new {page = x}))
What is the VB.NET equivalent? I am stuck on the x url lambda bit.
MVC 3 is great but in some cases I am having trouble translating the Razor syntax. Anyone know of a good VB.Net Razor reference?

Is it possible to translate the following C# code into VB.NET, using VB 9.0?
delegate Stream StreamOpenerDelegate(String name);
void Exec1()

WorkMethod( x => File.OpenRead(x));

Can I do something like this?:
Private Delegate Function StreamOpenerDelegate(ByVal name As String) As Stream
Private Sub WorkMethod(ByVal d As StreamOpenerDelegate)
''
End Sub

I'm trying to write some documentation, but I don't know VB syntax. Often I use Reflector to translate it, but I'm not sure it's working in this case. I'm also not clear on where I would need line continuation characters. In VB9, it's not possible to have multi-line lambdas (or Sub lambdas, which I did not ask about). In VB9, all lambdas return a value, and must be a single expression. This changes in VB10. VB10 will allow the above syntax, but VB9 will not. In VB9, if the logic involves multiple code lines, it must not be a lambda; you must put it into a named Function and reference it explicitly.
Like this:
Private Delegate Function StreamOpenerDelegate(ByVal name As String) As Stream
Private Sub WorkMethod(ByVal d As StreamOpenerDelegate)
''
End Sub

I just downloaded the MVC 3.0 RC and I'm excited to start using it, especially the Razor view engine. However, due to a few stick in the mud type people here, we are stuck using VB.NET instead of C#.When I started trying it out, I noticed some quirks. If you are creating a Razor view using CSHTML, you can write code like this:
@foreach(string genreName in Model.Genres)
{
<li>@genreName</li>
}
Razor will automatically detect that the <li> text is an HTML tag and will switch out of "code mode". With a VB.NET VBHTML file, this doesn't seem to be working. It's making me put the @: keyword in front of each line like this:
@For Each genreName As String In Model.Genres
@:<li>@genreName</li>
Next
If I don't have it there, I get a runtime error. Also, the <text></text> tags don't seem to work.

I am getting extra whitespace characters rendered in my horizontal list of anchor tags below. This is causing a major CSS styling issue for me. I know this question has been addressed as far as a C# workaround is concerned (asp.net mvc razor extra space), but can anyone help me with a VB workaround? I don't have the advantage of curly braces to eliminate all whitespace in a single-line If condition.
I have managed to work around it for now by writing an HtmlHelper extension method, but this dynamic code is only used in one place (the master layout page). It seems to me that this should really be done in the .vbhtml page. Here is the erroneous code, along with commented-out attempts at workarounds. The goal is to create a horizontal list of "sibling" pages based on a site map, with slightly different styles for the current page's link and the link just before it. [Code]

End Function And I get this error: Compiler Error Message: BC30201: Expression expected.

How do I modify or create my own Html.ActionLink helper to accept and handle the first parameter (linkText) passed in as an empty string / nothing?Details: I currently have a strongly typed view that's passed a model which contains search results. My view loops through each item in the model and attempts to display a link to a contact with the following code:
@Html.ActionLink(currentItem.ContactName, "contact", "details", New With { .id = currentItem.ContactID }, Nothing)
Normally this would work just fine, but not every item in my search result has a ContactName. The Html.ActionLink helper errors when this first parameter is empty. In case it helps, here's the model property for ContactName (which is generated from a template due to Database First, so I don't believe it can be modified):
Public Property ContactName As String
I'd like to have a helper function that simply returns nothing if the ContactName is an empty string / nothing.I'm guessing I need to extend this helper, and I've struggled to find any good, up-to-date resources in VB.net for extending helper functions. Other approaches are more than welcome if they're considered best practice. I'm working in VB.net, MVC3, and Razor in the ASP.net 4.0 framework.
How do I reference a Namespace in .NET MVC3 with the Razor view engine?
I understand this can be done in C#:

I'm creating a new website in Visual Studio 2010 Ultimate / vb and I want to add things to it, to jazz it up. So I'm adding new projects from the VS online templates. It seems there are many more projects in c# than vb. I'm trying to figure out if it's okay to add a c# and razor project to a vb website, because if not, I'll start the website in c#.
Will mixing languages between projects within your website present issues in the future when it comes time to build and publish? Or is it recommended I begin the website in c# (since there are more projects within VS) and keep the languages the same throughout the website?
In other languages (PHP/Python), I am used to creating a class which represents a given HTML page layout. These classes can have an unlimited number of attributes and dynamic features, such as Navigation (multi level), error messages, info messages, footer text, etc... Most of these items have defaults, but may be overridden on a per-page level. For example:

My question is: how do I implement similar functionality into ASP.Net MVC 3 Razor (VB)? So far, I have been able to see how you can use ViewData to pass various bits of data to a view. Also, I have been working with strongly typed views. Frankly, I'm not sure who's job it is to have this logic, the controller or the view (or is there a model that should be in there somewhere). Here is a summary of what I am shooting for:
A single place to initialize the default values for the layout (like the first layer of navigation, etc...) Strongly typed attributes, such as Public Readonly Property Nav1 as List(of NavElement) And a single place to render these layout elements (I assume _Layout.vbhtml) forgive the here-and-there of this post... I'm trying to figure out the "right way" it's done on a platform that is both new (Razor) and new to me (ASP.Net MVC).
MVC 3, VB.NET. I have a form in my app that gets basic information from the user and then allows them to upload a resume. I am accomplishing this right now by using a redirect to a different form that's only purpose is to select the file for uploading and then submit it.. Sloppy in my opinion.. I have tried to do it from the same form but the file is being lost on submit.. While I am not certain of it I believe it is because I am not using the correct syntax in the form to handle the file.[code]
