Due to the nature that it is difficult to debug msbuild custom task, I thought if I can use it in a way to streamline my debug workflow. one pack command will complete the following steps. - pack - add the package into local feed source - add the package to global-packages folder My current workflow is below. It is a manual process. It is realy a pain this way: - pack - nuget add [package-name] -source C:\nexus\.
