This example requires that you are running Virtuoso with CLR support.</p> <p>Using a text editor create a C# source file in the server root directory called sanity.cs, with the following contents:</p> <div> <pre class="programlisting"> using System; public class sanity { public static string test(string name) { return "Hello "+ name + ", from Virtuoso"; } } </pre> </div> <p>This sample needs to be compiled into bytecode assembly before it can be used. Use a command prompt that is suitably set up to find .NET utilities in its path, the .NET Framework SDK installation provides a shortcut in the Start menu to a command prompt that is preconfigured. From the command prompt change directory to the Virtuoso server root containing the C# source file. Execute:</p> <div> <pre class="programlisting"> C:\Program Files\OpenLink\Virtuoso 3.0\bin>csc /target:library sanity.cs Microsoft (R) Visual C# .NET Compiler version 7.00.9466 for Microsoft (R) .NET Framework version 1.0.3705 Copyright (C) Microsoft Corporation 2001.
