I'm trying to create the AppDomain from the unmanaged C++.
I can create the AppDomain without problem by method
ICorRuntimeHost.CreateDomain. But I cannot create the domain with shadow copy
turn on.

Here is the steps.
- create the domain setup by ICorRuntimeHost.CreateDomainSetup
- set the required property of domain setup
PrivateBinPath, ShadowCopyDirectories, CachePath and ShadowCopyFiles
(with value "true")
- create the app domain by ICorRuntimeHost.CreateDomainEx

The new AppDomain did not copy the assembly to the cache path.
I also tried this code in managed env with C# and it works just fine.
Did I do anything wrong ?

Thanks,
Atipon

You need to set AppName,

See my blog for more detail.

It doesn't work.

I've try this.
domainSetup->put_ApplicationName(_bstr_t("CLRDomain"));

You probably have to post full code sample.

It works now.
My mistake that I did'nt use the full path for
"domainSetup->put_ShadowCopyDirectories" :P
And you're right, I have to specify ApplicationName also to make it work.

But I wonder why C# does not need the ApplectionName for shadow copy ?

Thank you so much :)

It is explained in my blog,

Basically CLR automatically set the ApplicationName for you.

Shadow copy is a .Net technique used by the CLR that maintains a copy of
the metadata of the assembly. Yours is a COM dll and in COM
interoperability, the .net component does not know it is communicating
with a COM component and hence, when you attempt to make a shadow copy,
CLR would have looked for metadata which does not exist for the COM
component as interoperability works only with a wrapper class. Try
converting the COM dll into il and see if it works.

BTW, I am only providing you a possible answer; it is not guaranteed to
be absolutely correct.
