SUMMARY

This step-by-step article describes how to change the trust level that you assign to a specific assembly.

The level of trust that you assign to an assembly determines what system resources the assembly has access to. By default, trust is assigned to managed assemblies based on the zone where the assembly is located. You can also assign trust to assemblies based on the URL, the publisher, the strong name, and many other factors. By using the Trust An Assembly wizard, you can change the trust level of an individual assembly.

Note This procedure is useful only if you want to increase the trust level that you assign to an assembly. If you set the minimum trust level below the level that is granted to the assembly’s zone, the trust level of the zone is used.
