Why you do not use await in queries

[dimitkos]

Hello i started to read the documentation and I noticed this piece of code in the examples,

public class Query
{
public Task<Book?> GetBookById(
[Service] IMongoCollection collection,
Guid id)
{
return collection.Find(x => x.Id == id).FirstOrDefaultAsync();
}
}

so why you do not use await collection.Find(x => x.Id == id).FirstOrDefaultAsync(); ??

And general beyond this example I want to call any async service inside the query.

The return value from FirstOrDefaultAsync() is of type Task<Book?>, which means you do not need to await it since it matches the expected return type.

As a result, an async state machine is not compiled around it.

However, you can still use async and await if you prefer.
The difference is negligible, and Hot Chocolate understands both approaches.
