Paylocity was the first customer that Soma Somasegar, Corporate Vice President of the Developer Division at Microsoft, quoted as a customer reference during Microsoft's virtual Visual Studio 2012 launch!!!
In addition to citing what Paylocity is saying about VS2012, Microsoft also released another case study on Paylocity -- this time focusing on how we are using Visual Studio 2012. Originally we adopted VS2012 to start creating mobile apps with MVC 4 / HTML5 / CSS3 / PhoneGap, but what we found was that there are so many enhancements that this is a must-upgrade release of Visual Studio!
For more information, see Microsoft VS2012 Paylocity Case Study. While the recent case study focuses specifically on Visual Studio 2012, Microsoft's SQL Server group published a more comprehensive case study on Paylocity in 2011 which can be found at Microsoft SQL Server 2008 Paylocity Case Study.
