See Using the samples for help on compiling, setting up the debugger, and running the sample (either an exe or dll).
Open the solution using Visual Studio 2005.
Build the solution to make the 'DynamicLogoLayer' class library.
You will need to use this command in an application with a MapControl and a ToolbarControl.
Add the command to the ToolbarControl. The command can be found in the '.NET Samples' category with the name 'Show LogoLayer'.
Run the application and add any layer to use as a background.
Click the 'Show LogoLayer' command in order to add the logo layer to the map. You will notice that a logo will be added on the lower left corner of the map. Once you switch the map into dynamic mode you will notice the logo remains in place.
