Solution Review: Using Razor Components Features

To add the Counter element to the home page, we need to insert the <Counter /> markup element into the Index.razor file in the Pages folder. This can be seen on line 5 in the solution below.

To add attributes to an HTML element as a C# object, we need to define a field or property within the @code block that holds a dictionary with a string key and an object value. Then, we'll refer to the name of this field or property via the @attributes keyword in the HTML element we want to apply it to.

In the setup below, we defined the dictionary on lines 14–17 of the Counter.razor file. We then inserted this dictionary into the button element on line 9.
