[Firebird-net-provider] Invalid PInvoke metadata format exception on Connection Open

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

Using Visual Studio C#, .net 1.0, Firebird 1.03,  firebird net provider =
1.0.1241.28320.

I'm trying to copy an application over to a new machine (New).  I have =
it working on my development machine (Dev).  I installed .Net, Visual =
Studio, Firebird, net provider.  I can access the database on the New =
machine from the Dev machine using net-provider by pointing my =
connection string to it.  The same connection string fails on the New =
machine (I have tried LOCALHOST instead of the 192.168.1.3!

On the New machine I can access the db using IB_SQL or IBExpert.

However, when I run the app from the New machine with Visual Studio, I =
get the "invalid PInvoke metadata format" exception on the connect.  =
Here is my connection code:

FbConnection dbcon =3D new =
FbConnection("Database=3DC:\\cpt\\cpt.gdb;User=3DSYSDBA;Password=3Dmaster=
key;Dialect=3D3;Server=3D192.168.1.3");

dbcon.Open();  //exception thrown here

The new machine runs Win XP professional, same as my development =
machine.  I am at a loss as to what to look for next.  Tried everthing I =
can think of, but it must be some configuration problem.  I made sure =
that the ASP.NET User account has proper rights.

Thanks for your help!  I've had very few problems with your net provider =
until now.
