See this article on MSDN as well as the [QuickStart sample](http://samples.gotdotnet.com/quickstart/winforms/doc/WinFormsCreatingControls.aspx#Licensing Controls). You can validate a license for design time and only provide designer support, etc. if your license exists. Otherwise you just perform only the run time services of the control. Also take a look at the [LicFileLicenseProvider](http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemcomponentmodellicfilelicenseproviderclasstopic.asp?frame=true) class.

i actually think i read taht on gotdotnet , that control licensing doesnt work under asp.net .. but i could be way off here... but i think that was stated on some license page..

In your deployment project for you "developer" version, create a new registry key under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders. Use a unique string for the key name. The Default value should point to the directory where your assembly is located. You'll need two copies of your assembly, one in the GAC, and one in a normal directory. Hope that helps. Burt Harris

I have finally discovered that the Deployment project in Visual Studio .NET offers a GAC folder. I have just, when creating my deployment project, to place my assemblies in this folder. And now, I have another question: I would like that the setup program make the assemblies appear in the Visual Studio .NET "Customize Toolbox" dialog box. How to do that?

Yes, you are right... In fact, the correct place for this assembly would be the GAC (Global Assembly Cache). However, I don't know how to tell my setup program to place the assembly into the GAC. (I am creating a Deployment Project)

I'm hoping not to pay twice for something: #1, Pay MS so I can COMPILE programs/libraries #2, Pay someother company so $$ so someone else can't DECOMPILE the code I COMPILED Thanks anyhow. I'll take a look at the company if I can't find a free alternative.

Thanks. The Deployment wizard seems to be a very good starting point. It is a good surprise for me. Until now, I had not noticed its existence.

I agree. But you get the idea. She's so dirty, she threw a boomerang and it wouldn't even come back.
