(im using MVC4 VB). I want a FOR .. NEXT loop in my T4 “List.tt” template.
The first line of that template is:

<#@ template language="VB" HostSpecific="True" #>

This gives no syntax errors:

<# 
for i = i to 10 
 writeline(i) 
next 
#>

but that does not work: “Error 4 Compiling transformation: ‘i’ is not declared. It may be inaccessible due to its protection level.”

So it’s less VB then i expected…
Do you know the correct syntax and/or a website with full T4 documentation?

As the error says. You have to declare the variable

<# 
Dim i As Integer
for i = 0 to 10 
   writeline(i) 
next 
#>
