Re: [Firebird-net-provider] Invalid PInvoke metadata format exception

[Jim M. <jim...@co...>]

Thanks for your reply.  I looked at the links, had googled them before I =
think.  I have the problem fixed, but not sure exactly why.  I had =
uninstalled .NET 1.1, but that caused problems where my app could not =
find System and other derived classes.  It looked like a config file =
problem, so rather than wade thru that I reinstalled 1.1.  My app then =
worked!.  I'm still not sure exactly what went wrong, but I do =
understand that there was a conflict with the firebird provider and 1.1. =
 I guess I need to get a better understanding of how all the =
machine.config and others work!

  Hello Jim:

  If you are using Visual Studio 2002, it (VS) is rev-locked to =
Framework 1.0.   However if you
  install Framework 1.1, the installation will upgrade any applications =
in IIS to run with Framework 1.1 .
  Then when you use the web application, the application will recompile =
automatically under 1.1.
  I have the exact same situation because I am still doing web app =
development in Visual Studio (2002) and having my applications run in =
FrameWork 1.1.  Works just fine -- this is the great side-by-side =
feature of assemblies and forward version compatibility).   Had to do =
this because
  COM Interop in Framework 1.0 is buggy.  Most applications should =
upgrade to 1.1 without problems, however if you must run under 1.0 =
because of version dependencies then change the IIS mappings(.aspx,etc) =
for
  your application back to 1.0 framework.

  some helpful links for you:

    Carlos,

    I looked at my working Dev machine, and the References to System use
    1.0.3300.0, BUT in IIS the Mappings for the .asax file is pointing =
to
    Framework\v1.1.4322\aspnet_isapi.dll. Because I'm using Visual =
Studio 1.0,
    and it only works with Net 1.0, I don't see why it works.

    I thought I would have to change the mapping of .aspx to
    Framework\v1.0.xxxx\aspnet_isapi.dll.

    Can you shed any light on this?
