The type initializer threw an exception

[Guest]

We migrated our windows application from 1.1 to 2.0. The debug and Release
mode of the application work fine with some tweaking. But when the setup
project is migrated to 2.0 the installation gives the follwing error:

Message:The type initializer for
'Microsoft.ApplicationBlocks.Cache.CacheService'
threw an exception.

Did you notice this in your exception trace:

"
- <Exception ExceptionType="System.ArgumentNullException" Message="The cache
storage cannot be null. Parameter name: cacheStorage"
"

Yes, I have. We are using applicationblock version 1.0 for caching. it works
fine with framework 1.0. But when we migrated our application to 2.0 the
application works fine on VS 2005 IDE (both Release and Debug). When we
create a set-up package and install the follwing error occurs.

Have you checked that all the .config files are deployed correctly.
It seems to me that the <cacheStorage> is missing or cannot be found and for
that reason the caching application block cannot be initialized.

(check

needed).

We know that. But we don't know if anything has changed as far as 'config' or
'ref' is concerned when Applicationblocks 1.0 cache dll is used on frameowrk
2.0 applications.
