VB.net(v.1.1) mixed with C# (2.0)

[tzwanzig]

Greetings,
I have an application written,by someone else, with VB.net (v1) in a
subfolder, (./Editing )
I need to add to the application ASPx pages written in C# and ASP.net
2.0

Can anyone please tell me how to do that? Combining both versions?
I tried adding the DLLs and aspx pages from the old VB version in a
subfolder (./Editing ), resulting in an error

This is the whole structure:
- Pages on the root (C#) reads from this XML file.
- a subdirectory ./DataFolder that stores this XML file
- another subdirectory ./Editing (written in VB) that edits this XML
file (in addition to uploading images). Added difficulties come from
the fact that a temporary Access database is also used.

use the upgrade wizard to convert 1.1 project to 2.0 web site, which
support multiple languages.

change the name of the data folder to App_Data and place the access
database there.

all done.

If you absolutely cannot upgrade the 1.1 application (or command line
compile to 2.0), you will have to create an acceptable boundary.

In 2.0, that is either a web service or Remoting. If you can add 3.0 on top
of 2.0, you can create the 3.0 service using WCF. The 1.1 app will be able
to consume web services.
