How can I use LINQ for asynchronous queries in ASP.NET Core?

You can use the ToListAsync() method from Entity Framework Core to execute LINQ queries asynchronously. This allows your application to remain responsive while waiting for data.

Can you show me a code example?

Sure! Here's a simple example:

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

What if I want to filter the results?

You can add a Where clause to your LINQ query. For example:

public async Task<List<Product>> GetFilteredProductsAsync(string category) {
    using (var context = new MyDbContext()) {
        return await context.Products.Where(p => p.Category == category).ToListAsync();
    }
}

Are there any performance considerations I should be aware of?

Yes, be cautious with large datasets. Use pagination or filtering to limit the amount of data retrieved at once, which can improve performance.
