Currently using MS Access to build constantly changing front ends to SQL Server DBs. What is the most efficient programming platform for data entry user interface development in 2012? C#, C++, WPF? Needs to be able to be constantly changed, by the day; which is why we use Access now. Leaning towards some type of winforms rather than web -based because of the constant changing, no down time requirements.
Info about any platform or development software that allows this is very appreciated.
