trialware

Hello,

C# 2008 SP1

I am writing an application that I want to give to a select number of customers.

What is the best solution to use so that after the trail period (1 month) the application will no longer work.

I was thinking that if they are interested in purchasing the software I will give them a license key or something, to unlock the application.

I am have a very limited budget as I am working on my own. So is there any free 3rd party products that does this?

Many thanks for any advice,

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
