Building components using Blazor WebAssembly

Now we will build the same functionality using Blazor WebAssembly so that you can clearly see the key differences.

Since we abstracted the local dependency service in the INorthwindService interface, we will be able to reuse all the components and that interface, as well as the entity model classes, and just rewrite the implementation of the NorthwindService class and create a customer controller for its implementation to call for Blazor WebAssembly, as shown in the following diagram:

Configuring the server for Blazor WebAssembly

First, we need to build a service that the client app can call using HTTP:
