Question 1)<BR>First, there are two different types of installation available from Microsoft's site, the .NET Framework SDK and ASP.NET<BR>The .NET Framework SDK is about 123MB.<BR>The ASP.NET is about 18MB.<BR>If I install the ASP.NET does it automatically mean that I`m installing the Premium Version? Yes or No ?<BR><BR>Question 2)<BR>When installing the .NET Framework SDK I'm automatically installing ASP.NET which comes with the SDK but this ASP.NET is a Standard redistribuable one is that right? Yes or No ?<BR><BR>Question 3)<BR>Now I bought the Professional ASP.NET wrox book and in page 10 they mention that the Premium Version contains additional features such as:<BR>-Output Caching<BR>-Web Farm Session State<BR>-Code Access Hosting (sandboxed security for ASP.NET)<BR>-Support for 4 CPUs and above<BR>Assuming that the answer from question 1) is Yes then why is it that downloading the ASP.NET Premium Version (18MB) would contain additional features that aren't contained in the 128MB .NET Framework SDK? <BR><BR>Question 4)<BR>If the ASP.NET Premium Version holds more features, then why would someone what to download a bigger file (123MB) without having these features inside it?<BR><BR>Sincerely<BR>Vlincehttp://www.aspfaqs.com/aspfaqs/ShowFAQ.asp?FAQID=162<BR><BR>hth
