Say I develop an application that has an SQL Server 2000 back end with
ASP.NET front end. All the business logic is in the aspx pages. I want to
sell this as a package that some one can install on their server or even
desktop (replace SQL Server with MSDE). I don't want people reverse
engineering the logic inside of the aspx pages. Is there a way to prevent
this?

Also, I could probably put most all of the logic inside of a VB.NET EXE.
There would still need to be some logic in the aspx pages so I can't
completely get away from it. Any suggestions on a good method for this?

Thanks,
Brett

How about putting the business logic in the compiled code behind ? Or better
in a library called by code behind or aspx ?

then you can use one of several JIT obfuscator to make reverse engeneering
harder.

The whole point of aspx is that it is compiled "at first call".

Hi Brett,

If the logic is in the codebehind, you can obfuscate it with a tool like
this:

http://www.aspose.com/Products/Aspos.../Overview.html

I'm not aware of a tool that does the same for logic that is in .aspx files.
Of course if you can wait until the .NET 2.0 beta....

I'm new to ASP.NET. What are the file extensions that the compiled code
behind is stored in? Are you referring to ASP.NET or VB.NET code when you
say compiled?

When you say library, are you referring to say a VB.NET DLL that the aspx
pages create an object for?

Can you elaborate on this a little more: "then you can use one of several
JIT obfuscator to make reverse engeneering harder." Would this have any
performance hit?

Thanks,
Brett

Thanks. That's pretty neat. Have you used that program?

What will .NET 2.0 offer in this way? Also, when will it be released?

It will probably be a while until I will upgrade to .NET 2.0 since the first
version will probably be a little rough around the edges.

I see what the obfuscators do now:
http://www.devdirect.com/ALL/OBFUSCA...PCAT_2014.aspx. Do you have a
preference for one? Possibly free?

Thanks,
Brett

Hi Brett,

Check the details here on compilation in ASP.NET 2.0:

http://msdn.microsoft.com/asp.net/wh...ternals_topic3

As for the release, my guess is late fall for the final release. I'm
guessing September 25th for the beta 2 which should include a "Go Live"
option.

That seems rather far away...

Oops. I mean to guess April 25th for beta 2. My guess for the final release
