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.
<h1>Hello, world!</h1> Welcome to your new app. <MyComponentLib.MyComponent />
@using MyComponent <h1>Hello, world!</h1> Welcome to your new app. <MyComponent />
