<para>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 code groups whose membership conditions match a given assembly and their child code groups apply policy.</para>
<para>Like any code group, <see cref="T:System.Security.Policy.FirstMatchCodeGroup" /> only applies when its membership condition matches evidence for an assembly. If there is a match, it tests the membership condition of each child in order, stopping when the first match occurs. The result of <see cref="T:System.Security.Policy.FirstMatchCodeGroup" /> is the union of the policy statement of the root code group and the policy statement of the first child group of that code group that matches.</para>
<para>
<see cref="T:System.Security.Policy.FirstMatchCodeGroup" /> is intended for programmatic use by application domain hosts to set domain policy.</para>

<para>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 policy statement for the code group, including evaluation of child code groups.</para>
<para>For first-match code groups, each child code group's membership condition is tested against the evidence in the order in which they were added; only the first match is resolved with the evidence set. If there are no matches, the policy statement of the parent first-match code group applies. The matching child code group type determines how all child groups under it are applied, depending on how the <see cref="M:System.Security.Policy.CodeGroup.Resolve(System.Security.Policy.Evidence)" /> methods of these child groups work.</para>
<para>The .NET Framework security system uses <see cref="M:System.Security.Policy.CodeGroup.Resolve(System.Security.Policy.Evidence)" /> on the policy levels to determine which permissions to grant to loaded code from the resulting policy statements and the code request on the assembly.</para>
<para>This operation of this method is as follows: </para>
<para>If the membership condition does not match the specified evidence, return null; otherwise, set the permission set to be returned (P) equal to the code group's policy statement and continue. For each child code group, resolve the code group with the same evidence; if the result is not null, return that policy statement. If no child code group matched, return P (the parent's policy statement).</para>

<para>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 contains child code groups, which in turn can have child code groups as necessary to reflect the complete set of code groups that were matched by the evidence provided.</para>
<para>For first-match code groups, each child code group's membership condition is tested against the evidence in the order in which they were added; only the first match is resolved with the evidence set. If there are no matches, the policy statement of the parent first-match code group applies.
