When I am developing a DNN Module or even a DNN Platform change I typically configure my development enviornment to output the assemblies in the bin directory or I manually copy over the assemblies and the pdb files. This turns into a very tedious process very quickly when I am trying to rapidly develop or debug DNN Code.

As a consultant I work on several different projects throughout a calendar year and I may need to circle back to old projects. It is very useful for me to have a virtual machine I can just boot up to pick up exactly where I left off. This also makes creating a new development enviornment super easy for me, I just spin up a new virtual machine and I am ready to go.
