.Net licensing with Registry

1- You must use your LicenseProvider on the top of your control class like:
2- You must check the validation of License in constractor's control class by
LicenseManager.Validate(typeof(MYControl), this);
3- You must define you specified MYLicenseProvider and override GetLicense function and read something from registry and return a valid instance of "Licence".

PS: The promise is that you define your License class and return one object of that
public class MYLicense : License {...}
PS: Another application can fill up registry for use by this control

.Net Licensing with LIC file

Microsoft solution for Control .Net Licensing (that we call FILE LICENSING)
1- You must use the
on the top of your control class
2- You must check the validation of License in constructor’s control class by
LicenseManager.Validate(typeof(MYControl), this);
3- To run the application, you must use one file (with below spec.) near the executable (or dll) control.
FileName: [MYControlNamespace].[MYControlClassname].lic
Content: [MYControlNamespace].[MYControlClassname] is a licensed component.

This is the most simple microsoft solution, that can be advance!

.Net Licensing

Step by Step with .Net Licensing (for Control or Form)
If you wanna build a control (that we called NewControl) and use the .Net Licensing for that, go ahead:

1-The licensed control requests a license from the LicenseManager in its constructor.
[PS1: LicenseManager is a sealed (not inheritable) class for provides usefull properties and methods for connecting to a LicenseProvider]
license = LicenseManager.Validate(typeof(NewControl), this);
2- The our LicenseManager rerequests a licence from the LicenseProvider with GetLicense().
[PS2:We can define our LicenseProvider at the top of our class's control (that we called NewLicenseProvider)]
public class NewControl : System.Windows.Forms.Control{ ...}
3- We must declare a NewLicenseProvider of System.ComponentModel.LicenseProvider and override the GetLicense like :public
override License GetLicense(LicenseContext context, Type type, object instance, bool allowExceptions)

We want to talk more about this ...
