ThreadPool.SetMaxThreads Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

This member can be used only by trusted applications. If you try to use this member in a partial-trust application, your code will throw a MethodAccessException exception. This member is security-critical, which restricts its use.
