BadImageFormatException

Aug 9, 2008 at 11:01 PM
Hello!

I get this exception when I try to run N2 on IIS7 instead of Cassini. The exception is thrown when I load the root of the site, ie nothing is accessible.

System.BadImageFormatException: Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format.

I looks like other users of SQLite have had the same problem: http://forums.subsonicproject.com/forums/t/2680.aspx

I'm also on Vista 64 bit.

Any ideas?

Try to download and use the 64 bit version of the library.

Hello!

I got the 64 bit version and got another error.

I'm using the complete source. I just copied the SQLite dll into the Templates.UI bin directory.

The new error I get is:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I want to use SQL Server 2005 and I have set up the database and changed the connection string in web.config. I have also completed the installation (using Cassini).

What I'm trying to do is using multiple host names and this problem occurs when I try to browse the site on IIS7.

Hello!

Debugging some points out the it is the database connection that wasn't working ok.

I had trusted connection which worked ok with Cassini since I had started VS as administrator, but then in IIS7 I had the default AppPool setting (with Network Service as the process user).

Sorting the rights out solved that problem.

However, to give you some feedback about the problem, I couldn't really figure out which object caused the NullRefException. When I was debugging, all objects looked ok. You might want to have a look at that still though.

Thanks for telling. I've fixed the bug.
