Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


Code groups are the building blocks of code access security policy. Each policy level consists of a root code group that can have child code groups. Each child code group can have their own child code groups; this behavior extends to any number of levels, forming a tree. Each code group has a membership condition that determines if a given assembly belongs to it based on the evidence for that assembly.

Only those code groups whose membership conditions match a given assembly's evidence will be applied. If a matching code group has child code groups, then those children whose membership conditions also match the supplied evidence will likewise be applied.
