How to get Storefrontcontext in XC 10.1

Question

Using SC10.1 & XC 10.1
I'm trying to get catalog items with a search criteria.
The code in this Sitecore document to get the Storefrontcontext is not working.

var searchManager = CommerceTypeLoader.CreateInstance<ISearchManager>();
var storefrontContext = ServiceLocator.ServiceProvider.GetRequiredService<IStorefrontContext>();
SearchRepository searchRepository = new SearchRepository(searchManager, storefrontContext);
searchRepository.SearchCatalogItemsByKeyword("mdn","Brand", 10);

'IServiceProvider' does not contain a definition for 'GetRequestService' and no accessible extension method 'GetRequestService' accepting a first argument of type 'IServiceProvider' could be found.

Solution 1 : You can create a constructor and then find it from there as follows -

public IStorefrontContext StorefrontContext { get; set; }

public ISearchManager SearchManager { get; set; }

public YourController(IStorefrontContext storefrontContext, ISearchManager searchManager)
{
    this.StorefrontContext = storefrontContext;    
    this.SearchManager = searchManager;   
}

Then you can use your above code as -

SearchRepository searchRepository = new SearchRepository(this.SearchManager, this.StorefrontContext);
searchRepository.SearchCatalogItemsByKeyword("mdn","Brand", 10);

Solution 2 : If you want to use your code as is then add reference of Microsoft.Extensions.DependencyInjection.Abstractions.dll in your solution and use using Microsoft.Extensions.DependencyInjection; in your class

EDIT : If you haven't added your controller in config then need to add it as below. Create a patch file and add below lines -

<services>
      <register
        serviceType="abc.Feature.Catalog.Controllers.YourController, abc.Feature.Catalog"
        implementationType="abc.Feature.Catalog.Controllers.YourController, abc.Feature.Catalog"
        lifetime="Transient" />
</services>
