hi group

this might be another basic question from my end :(
my system : windows xp pro sp1, mono1.1.4 with xsp 1.0.6

i was trying following example
http://samples.gotdotnet.com/quickstart/aspplus/doc/businessobjs.aspx [ex
1]
this example has explains how to use local vb.net assemblies in asp.net

the vb file peacefully compiles on mono with mbas into a 2.5kb .dll file
and shows desired op with mono + xsp .

i copy the same dll and the aspx file into inetpub/wwwroot of iis and this
works peacefully well.

what i actually wanted to do is completely opposite of this .

i compiled the same vb file with MS.NET (1.00.3705 ) vbc complier into a
dll  of size 4.5Kb and run it in IIS . works cool .

now i simply copy this dll into the bin directory of my mono xsp
application  and restart xsp . it fails :((

<error>
Server error in '/' application

and xsp show following warnings :
