Import feature flag helpers globally

In your _ViewImports.cshtml add the following line

@addTagHelper *, Microsoft.FeatureManagement.AspNetCore

Anywhere in your views you can now surround the parts of the page that make up the feature

<feature name="FeatureX">
    <p>This can only be seen if 'FeatureX' is enabled.</p>

or add display the contents conditionally if Any or All the referenced features are enabled

<feature name="ShoppingCart,Checkout,Donation" requirement="Any">
    <div>checkout logic</div>

It's good practice to create a static class or strings or an enum for your features collection to avoid typos. Feature flags in C# work with both strings and enums
