It works on non-Rotor assembly with a fully qualified name too. Here is
what I did:
1) generate a brand new strongname pair:
C:\sscli\tests\dev>sn -k test.snk
2) create a simple assembly signed with the new key:
C:\sscli\tests\dev>csc /target:library test.cs
test.cs is:
---------------------
using System;
using System.Reflection;
[assembly: AssemblyKeyFileAttribute("test.snk")]
[assembly: AssemblyVersionAttribute("1.2.3.4")]
namespace MyNamespace {
public class MyClass {
public MyClass() {
}
public int MyMethod() {
return 1234;
}
}
}
---------------------
3) add the assembly to the GAC and make sure that it is there:
C:\sscli\tests\dev>gacutil /i test.dll
C:\sscli\tests\dev>gacutil /l test
The following line was somewhere in the output of the last command:
test, Version=1.2.3.4, Culture=neutral, PublicKeyToken=13fc20dbd9a37515,
Custom=null
4) modify ffitest
C:\sscli\tests\dev\ffitest>build
The important part of ffitest.cpp is:
-------------
hr = ClrCreateManagedInstance(
L"MyNamespace.MyClass,test,Version=1.2.3.4,Culture=neutral,PublicKeyToke
n=13fc20dbd9a37515",
IID_IManagedInstanceWrapper,
(void**)&pWrap);
if (FAILED(hr)) {
fprintf(stderr, "ClrCreateManagedInstance failed with
hr=0x%08x\n", hr);
return 1;
}
VariantClear(&RetVal);
hr = pWrap->InvokeByName(
L"MyMethod", CorFFIInvokeMethod, 0, NULL, &RetVal);
if (FAILED(hr)) {
fprintf(stderr, "InvokeMethodByName failed with hr=0x%08x\n",
hr);
return 1;
}
printf("MyMethod() returned %d\n", V_I4(&RetVal));
-------------
5) verify that it works:
C:\sscli\tests\dev>ffi_test.exe
MyMethod() returned 1234

Subject: Re: [DOTNET-ROTOR] Hosting Rotor
Jan, I would hate to be the one to disagree with you, but.... In my
example, Hello *was* installed in the Rotor GAC. That was the first
thing I thought of. Now, again, it's always possible that it's just me
being brain-dead, but can you try the test with a non-Rotor assembly?
