Performance Optmization with .NET

I have a web service, so the handler is called multiple times concurrently all the time.

Inside I create SqlConnection and SqlCommand. I have to execute about 7 different commands. Different commands require various parameters, so I just add them once:

command.Parameters.Add(new SqlParameter("@UserID", userID));
command.Parameters.Add(new SqlParameter("@AppID", appID));
command.Parameters.Add(new SqlParameter("@SID", SIDInt));
command.Parameters.Add(new SqlParameter("@Day", timestamp.Date));
command.Parameters.Add(new SqlParameter("@TS", timestamp));

How to connect to an external SQL server database in ASP.NET / VB.NET

Connecting to databases in .NET is different if you are coming from other languages such as PHP. To connect to a database in ASP.NET / .NET in general, you use "Connection Strings" that essentially is the connection information to the database.

First and foremost, in your code behind file within an ASP.NET application (or simply the .vb or .cs file of your .NET desktop application), you will need to first import the namespace that has the relevant database-related classes and methods, etc.

Note: All examples use the Visual Basic language, but the concept is the same for both Visual Basic and C#, for example.
