In researching to make this work, I found several bug reports filed at 
php.net where things within mscorlib didn't even work (whereas other 
things within the same assembly - such as the example given on the 
dotnet man page - work fine), which I was able to replicate. That's what 
led to my loss of confidence in the dotnet class, and to looking for 
another way of doing it. (That, and a web page I found where one of the 
dotnet class developers said he had completely given up on it.)

After getting my custom assembly working with the UniversalCCW library 
(which provides a COM wrapper around any assembly), I tried it again 
with the dotnet class. I get pretty inconsistent results - sometimes it 
will return immediately, and sometimes it will sit for several minutes 
before returning - if it returns at all before timing out. When I tried 
the examples in the bug reports I referred to above, I got some generic 
error messages back (the same ones that are in the bug reports).
