VBNC Crash

Rate this Message:
Hi, I have a really large ASP.Net Web application that i need to port into other platforms. The Web app that i'm trying to port is mainly written in vb, and references a lot of custom dll's that have also been written in vb. I tried to build the application from bottom up, by creating a blank project that has nothing but a page with a label. Mono Migration Analyzer pointed a few issues with the dll's, which i could find a way around, or temporarily commented out. For testing purposes, i'm using XSP2 server. The same set of dll's in a c#web project compiles and displays the page, whereas it fails to do so in a VB web Project. A lot of investigation with one of the dll's showed me that Extension Methods was the issue with that particular dll. But in the VB compiler page in Mono site tells me that extension methods do work.
I would like to know why i get a vbnc crash inspite of the method being supported. Is it something im doing wrong?? Btw im using Mono- 2.4.2.3. Any help would be great. Thanks, Vijay. |

Hi,
Im sorry, my bad. I thought i had seen it in VBCompiler page in mono, but i guess i was wrong. >Everything in VB8 (which came with > VS2005) is supported, anything newer (VB9 / VS2008) is not. Well something that occurred to me when i read this. If Methods in VB9 are not supported, then why am i getting no issues under the "Missing" section of the Mono Migration Analyzer? Technically, when you say its not supported, shouldn't it mean that those methods are missing from mono? Thanks, Vijay.

With VB8 I mean the VB compiler which came with VS2005 (and with VB9 I mean the VB compiler that came with VS2008). If you compile and run on Windows you're using MS' VB compiler (vbc), and if you run MoMA on the assemblies you have then you won't see any problems. However if you copy your web app to linux and run with mono you're using mono's VB compiler (vbnc), and here is where the problem comes: it doesn't know how to compile the sources if you used new features in the VB9 language (extension methods is one of them). One way around this is to use precompiled web sites, here are a couple of links that might help you: http://www.mono-project.com/Release_Notes_Mono_2.4#Precompiled_Web_Sites http://gonzalo.name/blog/archive/archive-2009-Feb.html Rolf > > Thanks, > Vijay. > > > Rolf Bjarne Kvinge-2 wrote: > > > > Hi, > > > >> > >> Hi, I have a really large ASP.Net Web application that i need to > port > >> into other platforms.
