[DotVVM](https://www.dotvvm.com) lets you build interactive web UIs with **just C# and HTML** using the **MVVM** approach.



It simplifies building of **line of business web apps** and ships with many built-in controls like [GridView](https://www.dotvvm.com/docs/controls/builtin/GridView/latest), [FileUpload](https://www.dotvvm.com/docs/controls/builtin/FileUpload/latest), [Validator](https://www.dotvvm.com/docs/controls/builtin/Validator/latest) and more.



## How does DotVVM work?



The **Views** in DotVVM use HTML syntax with __controls__ and __data-bindings__.



The **ViewModels** are plain C# objects with properties and methods.



You can access the ViewModel properties using `{value: Name}` and call ViewModel methods using `{command: Submit()}`.



```html



    





    





    



```



```C#

public class ContactFormViewModel

{

    [Required]

    public string Name { get; set; }



    [EmailAddress]

    public string Email { get; set; }



    public void Submit()

    {

        // ...

    }

}

```
