+## Set the stack size for threads created by the .NET runtime
+
+- The default stack size is dictated by .NET and OS policies. The default stack size for .NET apps is 1.5 MB on Windows and macOS, and 8 MB on Linux. The default stack size when .NET runtime is hosted (for example, COM components) is dictated by the hosting process.
+- This setting allows overriding the default for threads created by .NET runtime. For example, threads created by the <xref:System.Threading.Thread.%23ctor*> API.
+- The specified size should be between 64 kB and 2 GB and a multiple of the natural allocation granularity of the OS.
