[Mono-dev] Compiling System.Web with CSC

[Kornél Pál]

Hi,

I think the only solution to read PDB files is to use DIA. If you do so
there is no difference between .NET 1.1. a .NET 2.0 PDB files as you can
read the using the same interfaces methods. In other words your DIA base
code should work with .NET 2.0 PDB files as well.

Or do you use some other solution to read PDB files?
