[Blazor Server-Side]Creating a list in the razor file for multi-rows input

Hello,

I am trying to create a very simple scenario with multiple rows in one go. However, to get to that point I wanted to use a simple list. Following is my code. Admittedly, I am new to both C#/ASP.net so apologies if it is a user error.

Describe the bug

It is throwing CS1519, CS1031, CS8124, CS1026, CS1002 messages.

To Reproduce

//the definition of the properties is in a separate file public class NewRow { public string MaterialIdInp {get;set;} = String.Empty; public string QuantityInp {get;set;} = String.Empty; }

List matMvtNewDetails = new List(); matMvtNewDetails.Add(new NewRow()); //OR matMvtNewDetails.Add(new NewRow() {MaterialIdInp = "Hello", QuantityInp = "0" });

Expected behavior

I would expect to be able to create a list of class structure.
