I have Frameworks v1.0 and v.1.1 installed on my webserver and a web app
that is compiled in v1.0. I added <requiredRuntime version="v1.0.3705"
safemode="true"/> to the Configuration - Startup in the web.config file and
assume that the app is now using the v1.0 Framework. When I read
System.Environment.Version though, it returns the 1.1.

Is System.Environment returning only the installed version and not the
running version, or is there more required to force the app to v1.0?
