How to use linq select in template?

[biplan66]

I have an array from an external assembly that I want to output.
So, I want to print List with indexes.

@foreach (var item in Model.Collection.Select((value, int i) => return new { i, value }) 
{
<div>@item.value</div>
<div>@item.i</div>
}

I got an error: Unable to compile template: om00yyhz.oz1(48,131): error CS1977: Cannot use a lambda expression as an argument to a dynamically dispatched operation
How can I fix it?

What am I doing wrong?
I got an error: System.Collections.Generic.List does not contain a definition for 'Select'
And I use builder and addAssemblyReference builder.AddAssemblyReference(typeof(Enumerable).Assembly);

So, I use for and foreach to solve my problem))
How can I connect an assembly to use the Select method?

Yep, please refer to this unit test code:
