ConnectionOptionsResolvers are created through MEF. As Kim says, your class needs to be public and have a public default ctor or alternatively a public ctor marked with the ImportingConstructorAttribute if you wish to inject dependencies.

 

This is actually a Cocktail issue, not a DevForce issue per se, and Marcel is traveling right now.  I can try to help, but you may need to repost this in the Cocktail section of the forum to ensure Marcel sees it.

 

My first guess at why you'd get a MethodAccessException when looking for your DealerliveConnectionOptionsResolver constructor is that you don't have a public parameterless constructor defined for the class.  If you do, or don't have any constructors defined, then my next thought would be the class definition.  Reflection in Silverlight works only with public types and members, or internal types and members if you explicitly grant access.

 

Im trying to authenticate a user using AuthenticationService and an implementation of IEntityLoginManager

My users have different database so I had to implement IDataSourceKeyResolver, all this works using aspx pages, but when i try the same thing in Silverlight i get this error

 

{System.MethodAccessException: Attempt by method 'Microsoft.Internal.ReflectionInvoke.SafeInvoke(System.Reflection.ConstructorInfo, System.Object[])' to access method 'ClientService.Authentication.DealerliveConnectionOptionsResolver..ctor()' failed.

Any help will be appreciated, thanks
