Thanks to a Q&A on stackoverflow I just found out how to determine the installed version on my hosting provider's server. Now I need to know what that number means.
Using <%=Environment.Version%> on my local machine returns 2.0.50727.3053.
Can someone give me a list of the version 1, 1.1, 2, ect.. to the actual Environment.Version codes or break down what that code means?
