It ensures that packages are built from clean code straight from sources control without contamination from the development environment.

When web packages are built on the build server, a ZIP package is created with a set of accompanying scripts, including SetParameters.xml, which contains settings that can be configured before deployment.

It is a security risk because anyone with access to source control can obtain details of production systems, which can be misused.

Cloud services don't support transforms by default, so we have to manually add config transform files and edit the project to achieve this; alternatively, we can use the Slow Cheetah tool.

It can help us check whether all the required files are included and that config transforms have worked.

The build server restores NuGet packages before building solutions but not projects, which means if we haven't checked in our NuGet package binaries (which we shouldn't), the build will fail.

We need to set the Output location setting...
