What are some examples of LINQ async queries?

Can you give me some examples of LINQ async queries?

Sure! LINQ async queries allow you to perform asynchronous operations on collections. For example, you can use ToListAsync() to fetch data from a database asynchronously.

How does ToListAsync() work in a real scenario?

In a real scenario, you might use ToListAsync() with Entity Framework to retrieve records from a database without blocking the main thread. Here's a simple example:

var users = await dbContext.Users.ToListAsync();

Are there other async methods I can use with LINQ?

Yes, you can use methods like FirstOrDefaultAsync(), SingleOrDefaultAsync(), and CountAsync() for various operations.

Can you show me an example of using FirstOrDefaultAsync()?

Certainly! Here's an example:

var user = await dbContext.Users.FirstOrDefaultAsync(u => u.Id == userId);
``` This retrieves the first user matching the specified condition.
