Resolves matching code groups.
Assembly: mscorlib (in mscorlib.dll)
Given evidence for an assembly to be loaded, this method evaluates the code group by first checking the membership condition against the specified evidence. If there is a match, this method returns a root code group. The code group that is returned may contain child code groups, which, in turn, may also contain child code groups, so the return value reflects the complete set of code groups that were matched by the evidence provided.
