Product Manager managing product listings and prices

For school we have to develop a product manager. The basic task is to add new products. A product has a name and a price.

I know the one or other class is currently pretty empty but its planned to add more methods.

The code is developed in MVC-format and comments plus texts are in German.

I would like to know what's good and what's bad (also why) and how I can improve the code in design, structure, variable/method naming, performance.

Program.cs

using System;
using Ferienaufgabe_2.Controller;

namespace Ferienaufgabe_2
{
    static class Program
    {
        /// 
        /// Der Haupteinstiegspunkt für die Anwendung.
        /// 
        [STAThread]
        static void Main()
        {
           ProductList productList = new ProductList();
           productList.RenderView();
        }
    }
}

Controller/ProductList.cs

using System.Windows.Forms;

namespace Ferienaufgabe_2.Controller
{
    class ProductList
    {
        public void RenderView()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new View.ProductList());
        }
    }
}

Model/Product.cs

namespace Ferienaufgabe_2.Model
{
class Product
{
    private string productname;
    private decimal price;

    public Product(string productname, decimal price)
    {
        this.Productname = productname;
        this.Price = price;
    }

    private string Productname
    {
        set
        {
            this.productname = value;
        }
        get
        {
            return this.productname;
        }
    }

    private decimal Price
    {
        set
        {
            this.price = value;
        }
        get
        {
            return this.price;
        }
    }
}
}

Utility/Validate.cs

```
using System.Text.RegularExpressions;

namespace Ferienaufgabe_2.Utility
{
class Validate
{
public bool IsValidPriceFormat(string value)
{
string strRegex =

To help you get started, here's how I would write the Product class

public class Product
{    
    public Product(string productName, decimal price)
    {
        this.ProductName = productName;
        this.Price = price;
    }

    public string ProductName { get; set; }

    public decimal Price { get; set; }    
}

I used public to denote the visibility of the class. By default, C# will mark classes as internal which may not be obvious to other people. I specifically state the visibility to avoid any confusion.

I suggest you consider using the camel case naming convention for locals, parameters, fields e.g. productName

In this case, I used auto properties e.g.

public string ProductName { get; set; }

No need to declare your own private fields (_productname), if you are not using them for anything. Consider using auto properties instead.
