I use a better way in Vazor to make use of tag helpers and other Razor capabililties.
This is a working VB.NET ASP.NET MVC Core Razor sample! I implemented a simple VBRazorViewEngine in the VbRazor project. To use VBRazorViewEngine in the web project: 1- Add a reference to VBRazor.dll 2- Added these two statements to the Startup.ConfigureServices method:
services.AddTransient(Of IConfigureOptions(Of MvcViewOptions), VBRazor.VBRazorMvcViewOptionsSetup)()
services.AddSingleton(Of IViewEngine, VBRazor.VBRazorViewEngine)()3- Creat a Razor Virew class: The VBRazor is just a VB class that implements the IVBRazor Interface:
Public Interface IVBRazor
ReadOnly Property Razor As String
End InterfaceThe Razor property uses the xml literals to compose the HTML code and returns it as a string.. Example:
Imports VbRazor
Public Class IndexView
Implements IVBRazor
Dim students As List(Of Student)
Public Sub New(students As List(Of Student))
Me.students = students
End Sub
Public ReadOnly Property Razor As String Implements IVBRazor.Razor
Get
Dim x = <html>
<h3> Browse Students</h3>
<p>Select from <%= students.Count() %> students:</p>
<ul>
<%= (Iterator Function()
For Each std In students
Yield <li><%= std.Name %></li>
Next
End Function)() %>
</ul>
</html>
Return x.ToString()
End Get
End Property
End Class4- To use the Razor View Class from the Controller: in the action method, pass an instance of the razor class to the View method, and pass the model data to its constructor:
Public Function Index() As IActionResult
Return View(New IndexView(Students))
End FunctionAnd that’s all! If you run the project, you will see the web page that VBRazor composed!.. In this example, it will be as in the image:
This was really easy, but needs more work, so I hope you start contribute to this project to make it a real productive tool! The first thing to do, it to create a VB.NET template for ASP.NET MVC Core. I had to create a C# project then convert it to VB!
The second thing to do, is to add intellisense support for html attributes in xml literals in VB!
We need to try more advanced pages with JavaScript and other components. I hope VB team give us the support wee need to make the most of xml literals.
