You are developing a library to support multiple ASP.NET MVC web applications on a shared server. The
library provides implementations of security algorithms.
If a problem with any of the security algorithms is discovered, a new version of the library must be
created and deployed. Application downtime during the update must be minimized.
You need to ensure that the new version of the library will be used by all applications as soon as
possible.
