Default GC mode for ASP.NET applications running on IIS 8.5 and Windows Server 2012 R2

Question

What is the default GC mode for ASP.NET (NET 4.5) applications running on IIS 8.5 and Windows Server 2012 R2?

Answer 1

Here's the startupFlags parameter passed to CorBindToRuntimeHost / CorBindToRuntimeEx by default:

STARTUP_CONCURRENT_GC | STARTUP_LOADER_OPTIMIZATION_MULTI_DOMAIN_HOST | STARTUP_LOADER_SAFEMODE | STARTUP_DISABLE_COMMITTHREADSTACK | STARTUP_HOARD_GC_VM

Additionally, pwszBuildFlavor is "svr" unless an administrator has modified the registry to specify a different value.
