What are some examples of using async in ASP.NET Core?

In ASP.NET Core, async programming is essential for improving performance. For example, you can use async and await with database calls to avoid blocking the main thread.

Can you show me a code snippet for an async database call?

Sure! Here's a simple example:

public async Task<List<Product>> GetProductsAsync() {
    using (var context = new ApplicationDbContext()) {
        return await context.Products.ToListAsync();
    }
}

What about using async with web API calls?

You can use HttpClient for async web API calls. Here's an example:

public async Task<string> GetApiDataAsync(string url) {
    using (var client = new HttpClient()) {
        return await client.GetStringAsync(url);
    }
}

Are there any best practices for using async in ASP.NET Core?

Yes, always use async methods for I/O-bound operations, avoid blocking calls, and ensure proper exception handling.
