I have developed advanced POS system as follows

front-end using VS2003 .NET 1.1
Back-office using VS2008 .NET 3.5

my problem is my .NET 1.1 compiled front-end is use more memory in run time more than same front-end compiled in .NET2.0

windows task manager shows .NET 1.1 exe using 50,000k - 70,000k and
.NET 2.0 compiled EXE use 25,000k - 50,000k in time is this possible. i thought older language are light to memory than newer version of them.

looking for better explanation from experts?????????????????

Yes, it's possible. However there may be several reasons for this, for example:

The framework itself is enhanced between versions to use less memory

The garbage collector is enhanced between versions to better clean up the memory.

.Net framework has bugs which may cause the program to use more memory. Depending on the version, there are 'lots' of fixes in Microsoft support.

and so on...

Good points, my 5.
I would also add: according to my observations, first decent version of .NET was 2.0. Everything prior to that was not really serious for an application developer, at least not quite mature for the serious use in the industry.
