Explain async and await

• async and await keywords are used for asynchronous operations
• awaiting a process puts in a separate task and returns the reference to that task.
• Once complete the runtime makes sure that the process starts execution back from where the await process occurs
• A method in which an await keyword is used should be marked async

public async Task<string> DoSomething() {
    var res = await httpClient.GetAsync("SOME_GET_API");
    return await res.Content.ReadAsStringAsync();
}
