So you think you have found an issue in AtomicMVVM but aren't 100% sure? Or you KNOW there is a bug but you want more insight for the fantastic bug report you are going to send? You could download the source, compile it yourself and change all the references and recreate it that way - but seems like a lot of work.
So to make it easier we support SymbolSource.org which is a public location for project source code and symbols (those .pdb files). To use it, simply in Visual Studio go to Tools, Options, Debugger and Symbols. Once there add the SymbolSource.org server and you will get full symbol and source code support!
