Since now I've used the excellent FluentValidation library to validate my model classes.

I've got a linq query, which is admittedly pretty large. I can't identify where it is going wrong because it ONLY happens on the remote server and I don't have the access to debug it.

Hi all, I'm currently porting a peace of code written in .NET 3.5 to 2.0. At some point in the code (heavy load) the AesManaged class is being used, are there any performance gains from this implementation compared to RijndaelManaged, and should there be any risk when changing from AesManaged to RijndaelManaged concerning heavy load? g...
