Question

I havent really found a solution seaching through SO.

…and suspect I should really do this in the Model…

but is it possible to have C# code blocks where adhoc code can be added eg:

@int daysLeft = CurrentTenant.TrialExpiryDate.Subtract(DateTimeOffset.Now).Days
@if (daysLeft <= 0) {
{
   <text>
   Trial period completed  
   </text>
}
else
{
   <text>
   You have @daysLeft days left of you trial
   </text>
}

Answer 1

Sure it is:

@{
    var one = 1;
    var two = one + one;
}
