.NET 4.0 Support

We've been hard at work brining full .NET 4.0 runtime compatibility. Most of the work has been completed but is still being tested.

Download the latest experimental release

NOTE: The experimental release will overwrite any previous installs. You will need to completely uninstall the experimental release to restore the GA version.

Additional Samples

Two additional samples have been posted to demonstrate the use of DeployLX Licensing in a Windows Application and an ASP.NET application.

Licensed Windows Application Starter Kit

Licensed ASP.NET Application Starter Kit

When you register a license for DeployLX by populating the SerialNumbers collection of the LicenseValidationRequestInfo class DeployLX will return the first license it finds that can be unlocked with the given serial numbers.

The next time you call Validate without populating the SerialNumbers collection, DeployLX returns a a trial license, or throws an exception that a valid license cannot be found.

When running a veiled assembly on your machine you may receive an message that DeployLX has detected possible attempts to tamper with the runtime executive.

Compatibility with 3.x Licensing Runtime

This release can be used as a complete replacement for version 3.x. It is backwards compatible except for a few very specific breaking changes. Existing licenses can be validated with the new runtime license without change. License servers upgraded to the new 4.x runtime can validate and authorize 3.x licenses without change.

Update 4/21: A recent change to the bug tracking software has made all tags private resulting in an empty list of breaking changes. A clone of the list has been published as a backup.

What about .NET 4.0?

Official support for .NET 4.0 will be announced a few weeks following the official release of .NET 4.0. Currently the Licensing component works without issues against the .NET 4.0 Release Candidate. The Code Encryption feature of the CodeVeil Component is not stable in applications running under the .NET 4.0 runtime.

I Have a 3.x License and Want to Upgrade

To purchase an upgrade, contact sales with your current serial numbers to request a quote.

If you have purchased the Embeddable C# Licensing Runtime for DeployLX Licensing you can embed it directly into your C# projects instead of referencing the DeployLX.Licensing.v4.dll. 

In this video we'll see how to use DeployLX to add copy protection to a simple Windows application.

Our sample will demonstrate a typical scenario where users are allowed to evaluate the software for a short time. Then should they decide to continue, they are required to purchase a license.

While it demonstrate protecting a Windows Application, the basic concepts apply to Windows Controls, ASP.NET applications and class libraries as well. 

After validating a license, get a TimeMonitor object. The TimeMonitor provides information about the state of a Time Limit. After obtaining a TimeMonitor you can use the exposed properties to query the state of the time limit.

var monitor = _license.GetTimeMonitor();
MessageBox.Show( 
    String.Format( "You have {0} of {1} remaining.", 
        monitor.TimeRemaining, 
        monitor.TotalTime ) );

After validating a license, get a UseMonitor object. The TimeMonitor provides information about the state of a Use Limit. After obtaining a UseMonitor you can use the exposed properties to query the state of the time limit.

_license = SecureLicenseManager.Validate( this, null, null );
var monitor = _license.GetUseMonitor();
MessageBox.Show( 
    String.Format( "You have {0} of {1} uses remaining.", 
        monitor.UseCount, 
        monitor.UseLimit.Uses ) );

This article will demonstrates how to create a custom translation for DeployLX Licensing forms and errors. This can be used to create a custom translation or change the wording of the form text in the default DeployLX Licensing v4.x screens.
