I want to download the source code of .NET Framework 4. From the official website, I get the files with the extension .aspx; WinRAR is pretending that those are broken CAB files, and Windows won't open them if they are renamed to .cab or .exe.
What is the actual type of those files? How to open them? Are they actual files or the website is just broken and sending random stuff?
.aspxfiles are for ASP.NET web forms development. Why do you need to open them? What are you trying to do? – James Mertz Feb 27 '13 at 21:37
