See
How to use ArcGIS samples
for help on compiling, setting up the debugger, and running the sample.
If the sample has associated data, you will find that the sample's zip file includes a "data" folder alongside the language folders.
However, you will need to update the sample to point to the location of the data once you have extracted all the files.
Open and compile the sample project in Visual Studio. If necessary, set up a debug application.
Start ArcCatalog, ArcMap, ArcScene, or ArcGlobe.
Click the Customize menu, and click Customize Mode. The Customize dialog box opens.
Under the .NET Samples category, drag and drop the Toggle ESRI Resources Window (VB .NET) or Toggle ESRI Resources Window (C#) toggle command onto the application, and click the command. The dockable window opens.
Dock the window in various locations on the application window, then float the dockable window.
Select one of the ESRI links from the combo box at the bottom of the dockable window to navigate to the related Web page.
