Maximum Pool Connections for HttpWebRequest in .NET <=4.5!
Did you know that in .NET Framework 4.5, the maximum number of connections in the pool for HTTP requests is controlled by the `ServicePointManager.DefaultConnectionLimit` property? 🔑
By default, this limit is set to 2 for the HTTP/1.1 protocol, meaning you can have up to two simultaneous connections to the same server. If your application requires more concurrent connections, you can increase this limit programmatically to meet your needs. 🚀
✨ **Tip:** To increase the connection limit, simply set `ServicePointManager.DefaultConnectionLimit` to a higher value early in your application’s startup process:
System.Net.ServicePointManager.DefaultConnectionLimit = 100; // Adjusts the limit to 100
Keep your HTTP requests efficient and your apps running smoothly!

Optimizing SQL Server Queries with Indexed Columns!
Did you know that using functions like `DATEPART(year, column)` in SQL Server can cause indexes to be ignored? 🔑
When you apply functions directly to columns in your WHERE clause, database engine often can’t utilize existing indexes efficiently. This is because the function needs to be applied to each row, which prevents the optimizer from using the index. This can impact query performance, especially in large datasets. 🚀
✨ **Tip:** To improve performance, consider adding a computed column that stores the materialized year. Index this column for faster query execution, especially useful in reports.

Entity Framework & Connection Pooling
Did you know that Entity Framework uses connection pooling based on the connection string hash? 🔑
Every time you open a connection, ADO.NET generates a unique hash. If another request uses the same connection string, EF reuses the existing connection, boosting performance and saving resources! 🚀
✨ **Tip:** If you have multiple applications connecting to the same database, consider adding an application name to your connection string. This prevents them from reusing connection pools, ensuring optimal performance for each app.
