How to licensce a .NET desktop application

[vighnesh]

Hi All

Is it possible to distribute .NET desktop appliation as "Trial" version (
limiting the usage to certain number of days ) and then for full time usage.
Like the commercial softwares , they offer "Trial/Demo" versions and after
purchase they work for full time and registered.

I have developed a .NET desktop appliction and I would like to distribute
the application as Trial version and upon regsitration will go for Full
version. Is there any free tools available to achieve this scenarion?

Please suggest the best possible way.

Thanks in advance.

Regards
Vighneswar

Hi,

This is a subject that arise frequently, in short there is nothing in the
framework to do this. you will have to implement it by your own, or use a
third party tool

Take a look in the archives and you will see different ways to deal with it.

You must use licensing - try searching on MSDN for License and
LicenseProvider.
Also, take a look at:
