> Ignite uses dynamically generated delegates to avoid constly reflection calls on hot
paths (invoking user-defined generic methods, constructors, etc) - see {{DelegateTypeDescriptor}}
and {{DelegateConverter}} classes.
> Investigate whether adding the following attributes to our assemblies affects performance:
> {code}
> [assembly: AllowPartiallyTrustedCallers]
> [assembly: SecurityTransparent]
> [assembly: SecurityRules(SecurityRuleSet.Level2,SkipVerificationInFullTrust=true)]
> {code}
> See
