I am customizing ArcMap using VS2008 with the Developer Kit for .NET. I have created a C# project with some commands and tools and an associated toolbar. I want to share some data among these items within the project (so that the data is available to each tool or command when it is executing), but I can't figure out how to do it. I'm pretty sure this is a simple question, but it's got me stumped for now. Can anyone give me some suggestions?
