I personally haven't used COM Interop yet, but perhaps the answer to your problem might be addressed in Rick's article.

>Just getting my feet wet with Com interop. I have developed a simple class in VB.Net complete with the appropriate interfaces and compiled it with COM registration. When I examine the object in VFP9 using the Object Explorer, after having scanned the registry, The object is visible with the class as expected. The methods are identified and all appears OK. But when I try to instanciate the object with

>o=CREATEOBJECT('aws2test1.tester')

>I get the error :

>Class definition AWS2TEST1.TESTER is not found.

>
>If I try to use

>o=CREATEOBJECTEX('aws2test1.tester',"","")

>I get the error:

>OLE error code 0x800401f3: Invalid class string.

>Any suggestions?
