Differences to standard sample installation
Installation of Newsletter template project is almost the same as of Sample project.
There are two main differences between Sample and Newsletter Template project. The one is that all folders, virtual directories end with _MailCenterSample instead of _Sample. The second difference is that the custom extension is set to .MailCenterSample instead of .Sample.
So, please, follow the Sample project installation guide, keeping in mind those 2 differences.
