Blazor FAQ - Component libraries

You can consume a library in either of two ways:

• Full name with namespace
• Using Razor’s @using directive

If the MyComponentLib is the component library and MyComponent is the component name, those are consumed like in the following.

Option 1

<h1>Hello, world!</h1>

Welcome to your new app.

<MyComponentLib.MyComponent />

Option 2

@using MyComponent

<h1>Hello, world!</h1>

Welcome to your new app.

<MyComponent />
