Commented Unassigned: Member resolving error in web projects [2071]

Hello,
Zyan.Library works fine in my windows project.
But in web(aspx) project sometimes I get the error below. Do you have any idea where the issue comes from?

Thx
Reinhold

Hi Reinhold,

please check if you're using the same Zyan.Communication.dll binary everywhere.
I've changed a lot of internals since the 2.4 release, LocalCallContextData class in particular.
Mixing up two versions of Zyan binary (2.4 release version and current development 2.4 version),
for example in your bin directory and in GAC, might result in odd behavior.

I'm not an ASP developer, so I've never tried using Zyan in web applications.
I can only suspect that partial trust execution mode might cause strange issues.

If the issue persists, please help me to reproduce it.
I need a small sample project that throws these exceptions.
Please zip the project and add it as an attachment to this issue.

Thanks, yallie.
