Version 2.0.6.1120 cannot be referenced in IDE

[xz89]

Hi,

Recently I found OpenPop.Net. It looks it's just I am looking for. I downloaded the version 2.0.6.1120, the assembly said is strong-named (signed). We have an IDE environment which only allows strong-named assembly. I couldn't reference the version 2.0.6.1120 in my IDE window. So I downloaded version 2.0.5 which is also strong-named assembly. The assembly of the version 2.0.5 can be referenced in the IDE. I wonder why version 2.0.6.1120 didn't work like version 2.0.5. Thanks
