I am trying to get strong naming working with my web deployment project and I'm having difficulties.

When I build the project I get:

Cryptographic failure while signing assembly 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\digitalwebviewer\3800da06\dd934212\App_Code.dll' -- 'Bad Version of provider. '

For the key file I am providing the same .pfx file that I use for our WinForms apps, where it works fine.

I get the same error if I try to Publish the web app with strong naming.

I've considered that .pfx files might not be supported by ASP.NET apps but I can't figure out how to get from a .pfx to a .snk file.

Does anyone know how to make this work?

Thanks,

Hi,

You can create PFX file using SN tool.

It is easy to create it using Visual Studio 2005 for your web application. For more information, see http://blogs.msdn.com/shawnfa/archive/2006/02/14/531921.aspx or http://www.securityguidanceshare.com/wiki/ASP.NET_2.0_Security_Questions_and_Answers_-_Strong_Naming_and_Signing

 

I hope this helps.

Thanks for the pointers.

Unfortunately my problem isn't generating a .pfx it is creating full (public and private key) .snk from a .pfx and the fact that VS08 appears to have a bug preventing the use of .pfx files for signing.

Perhaps SP1 will fix the issue.

Thanks,
