Context error on 64 bit IIS7

Post by edstaffin » Wed 17 Aug 2011 11:39

Here is my configuration:
Installled dcoracle570pro.exe.
Using linqconnect to an oracle 10g db.
Windows Server 2008 R2 64 bit w/ IIS7 all latest service packs.
IE version 8 installed.

When I run my app in the development server via visual studio 2010 on the above mentioned machine, works perfectly. No errors.

When run from the browser (IE8 ) outside visual studio I get the following error when going to a page that is using a datacontext. This makes no sense to me. How can it work in vstudio and not on IIS7? Is it a 64bit issue? Do I need to upgrade Devart? Help!!!

Server Error in '/VectorQC' Application.

I am Not a DevArt guy, but I think, that the Problem is more Set to your restrictions. It Sounds for me, As you do Not have enough Rights. This problem is Not a Devart's Problem.

Vs2010 will Start up with admin rights - the browser doesn't have such rights.

Hope this will help

Thanks for responding, but I don't get it. What restrictions are you talking about? What rights to what? How does the browser's rights have anything to do with a compilation issue on the server side?
Maybe I'm missing something.
Thanks ... Ed

Could you please describe the structure of your application? For example, please specify the following:
- whether the application is pre-compiled or not (i.e., if it is an ASP.NET application or an ASP.NET site);
- if the data context class and entity classes are declared in a separate assembly;
- if the 'Access' model property is set to 'Internal'.
