Its already too late, but it may help someone.

I've used Sqlite DLL in my project and when I deployed the code on sandbox environment, I was getting exception (see below)

[FileLoadException: Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)]

[FileLoadException: Could not load file or assembly 'System.Data.SQLite, Version=1.0.79.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)]

I added trust level within system.web in the web.config file and its working fine.
