+One of the problems reside in line 42 ("Protected Overrides Property
+AutoHandlers As Integer") and not in line 52 as shown in the compiler

+MonoBASIC: THIS IS STILL ALPHA AND UNSUPPORTED SOFTWARE, USE AT YOUR OWN
+RISK.

+testsrc.vb.txt(52,0) error BC30284: `ASP.index_aspx.AutoHandlers' no
+suitable properties found to override
+Compilation failed: 1 Error(s), 0 warnings
+[root@lwezel wwwroot]#
+
+
+I'd say, the property exists since in C# the ASP.NET generation is
+successfull.
+
+As I've seen, a second problem is the missing support of the AddressOf
+operator. But simply compile, you'll see...
+
+
+Steps to reproduce the problem:
+===============================
+1. Compile on MS.NET with P:\>vbc
+test.vb /r:Microsoft.VisualBasic.dll,System.dll,System.Web.dll,System.Data.
+dll /target:library
+2. Try the same with mbas and it will fail because of several problems
