How can I use LINQ in ASP.NET Core with async methods?

You can use LINQ with async methods in ASP.NET Core by utilizing the ToListAsync() method from Entity Framework.

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 use LINQ's Where method to filter results. 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 and avoid loading unnecessary data to improve performance.
