How use async and await in net core?
We add an async keyword to the method signature, modify the return type by using Task , and we use the await keyword when we call the GetAllCompanies awaitable method.

Asynchronous execution
An asynchronous query execute call does not block for results. Instead, a future is immediately returned from the asynchronous execute call. A future is a placeholder object that stands in for the result until the result is returned from the database.

What is an IQueryable in C#?
IQueryable<T> is a C# interface that lets you query different data sources. The type T specifies the type of the data source that you’re querying. Under the hood, IQueryable uses expression trees that translate LINQ queries into the query language for the data provided.
What is async method in .NET Core?
Asynchronous programming allows you to write programs that don’t block on each statement or instruction, meaning the computer can move on to other tasks before waiting for previous tasks to finish. As a result, asynchronous programming enables you to build applications that are more scalable and responsive.
What is synchronous and asynchronous in .NET Core?
ASP.NET Core apps should be designed to process many requests simultaneously. Asynchronous APIs allow a small pool of threads to handle thousands of concurrent requests by not waiting on blocking calls. Rather than waiting on a long-running synchronous task to complete, the thread can work on another request.

Can we use async without await?
