Hosting .NET Runtime in C++ Tip o' the day or "Where is IAppDomainSetup?"

  • Article

Are you hosting the .NET runtime and trying to create another AppDomain? Notice that you need to call CreateDomainSetup and cast the IUnknown to IAppDomainSetup to set properties? Notice also that IAppDomainSetup isn't defined in mscoree.h? Add the following (stdafx.h or anywhere else):

#import

<mscorlib.tlb>raw_interfaces_onlyno_smart_pointershigh_property_prefixes("_get","_put","_putref")

then you can say:

CComPtr

<mscorlib::IAppDomainSetup> pAppDomainSetup;

Ta da!
