.NET Framework Statistics

As part of our product planning, the DocuSign engineering team analyzed non-personally identifiable data from our web site to determine what versions of the .NET framework are installed on our customers' desktops. We’ll use this information to ensure DocuSign products will install quickly and easily for most users without requiring additional downloads.

If you are deciding between using .NET 3.5 and .NET 2.0, using .NET 2.0 will only reach 3% more users, without requiring them to download a newer version of .NET.

To gather this data we looked at a random fraction of web log data that represents roughly 13,000 unique visitors that visited our site with IE. Internet Explorer usually reports the version of the .NET framework installed (in the browser user agent string) when it requests web pages.

We used IP address and user agent string to determine uniqueness.  While most measures of unique users tend to over count (the same  user on two computers is counted twice), this method under counts.  

It's quite likely that multiple users with the same browser can send requests from the same IP address over time,  or even at the same  time if they share the same corporate proxy server. 

Some versions of Internet Explorer don't report the .NET version.  That's the unknown category in the graph.  If you know why that is, please let us know in the comments.

Of course your user base is different from ours, but we wanted to share our numbers to provide some broad insight into what's currently in use.
