+In order to properly test dnchost and mbahost,
+the managed BAs need to be published and a bundle needs to be built for each scenario.
+Making this happen on every build for the solution takes too long,
+so this project relies on manually running appveyor.cmd to publish everything before the tests can be run.
+appveyor.cmd needs to be ran again every time changes are made in other projects.
