I'm researching building a couple of custom tools. I downloaded and installed ArcObjects SDK 10.4 to include it in Visual Studio 2013 and 2015, but I'm having trouble finding any good examples on creating the tools. Our client wants one tool that will search for a value from a specific field("Loc_Num") within a specific set of layers and then highlight the feature it finds. They also want another one to do an address lookup, but apparently the built-in tool is not what they are wanting. If anyone could point me to a good reference on building these within VS 2013 or 2015, I would greatly appreciate it.
