One of the consistent themes that the Dev Center Team hears from the Windows developer community is that first impressions are important. Before launching a new app or game, it’s important to validate that the experience is working perfectly in production. At the same time, many developers may have disclosure concerns and want to control the announcement timing of new products. We’ve heard your feedback that testing in production before launch is critical to gain confidence in your products’ quality, and that you’d like to be able to do this testing without having the product visible to anyone beyond the intended audience.
