As requested, I have obtained a list of the top sites (by traffic)
that run on the Microsoft .NET Framework.
My methodology for obtaining this information was as follows.
I first went to:
Alexa provides daily updated traffic rankings that you can slice many
different ways (languages, categories, etc). For our purposes, the Top
100 English Language sites appeared to be the best choice:
From here, I looked at each site (starting with the one having the
most traffic and working down) and determining whether or not it had
.NET contained within its technical architecture.
Below is a list, in sorted order of most traffic first (as of the
today), of websites that met the criteria.
Top Sites (by traffic) Using Microsoft.NET Technology
1. Microsoft Network (MSN) - http://www.msn.com/
2. Microsoft Corporation - http://www.microsoft.com/
3. Xanga - http://www.xanga.com/
4. Orkut - http://www.orkut.com/
5. EarthLink, Inc - http://www.earthlink.net/
6. Hewlett Packard - http://www.hp.com/
7. Wal-Mart - http://www.walmart.com/
8. Best Buy - http://www.bestbuy.ca/
9. Monster - http://www.monster.com/
10. DoubleClick - http://www.doubleclick.com/
11. Expedia - http://www.expedia.com/
12. TigerDirect - http://www.tigerdirect.com/
After analyzing the 100 sites on the list, I was initially quite
surprised to see that only 12 of the top 100 visited english language
sites actually qualified. However, upon further reflection, it does
make sense. Microsoft.NET has been marketed mainly to support business
systems, and the large majority of the "high-traffic" sites cater to
the general public and do not facilitate the kinds of complex business
transactions that makes .NET valuable.
Upon realizing this trend, I thought you would find it valuable to
also have a list of companies which Microsoft has used as case studies
for implementation of .NET architectures. Since there is a nice
cross-section of different ways .NET has been used, you can pick and
choose to fit your needs. This set of case studies is available from
