Anyone knows where I can get a free or open source licensing/authorization module to integrate with my .NET Windows application? It should allow a few weeks grace period for testing the software and afterward force users to generate an authorization code. Application is in C#, but a module in any .NET language should be fine.
Sorry to seem unhelpful but .NET is like, the other camp when it comes to free/open source. It seems like you would have more help going to BING or Google for a module with a reasonable trial period if you haven't already, as those tools are primarily used to develop closed source/proprietary software.
