Hi,

I got this error while working on Data Access Logic components using the Enterprise Library.

The type initializer for 'Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.EnterpriseLibraryFactory' threw an exception.

I searched everywhere and found nothing but some fragmented advice related to medium trust. The actual problem was that I had a reference to:

Microsoft.Practices.EnterpriseLibrary.Data.dll
Microsoft.Practices.EnterpriseLibrary.Common.dll

...but I also needed a reference to:

Microsoft.Practices.EnterpriseLibrary.ObjectBuilder.dll

Reflection is at work here, so the compiler didn't catch the missing reference. I thought I'd post here to hopefully save someone else the trouble.

Thanks its helped me to solved my problem.
