OxygenBasic produces standard dlls.

Here is a demo 32bit standalone dll to try:

Code: [Select]

% dll
% filename "t.dll"
uses rtl32

function greet(s as char) as long, export
print "hello "+s
return 42
end function

I have never used .net but this enquiry might help:

OxygenBasic does not mangle DLL function names, and does not alter the case of the name,  unless you specify an alias to use.
