new PosExplorer exception

Question

Hi,

I'm at the very beginning of developing in Pos.Net.

I bought the Professional Guide to Pos.Net (a very good book) and I started with the first exercise.

When I try to instantiate the PosExplorer class I receive a general exception...

My example is the very simple. My Form, after the InitializeCmponent(), has

myExplorer = new PosExplorer(this);

and there is an exception.

In my machine (WIN 7 64 BIT) I have VS2010 and only the 1.12 SDK installed.

Someone can help me??
Thanks in advance

This is the POSReady forum. There is a POS for .NET forum available so you can get the most feedback - http://social.msdn.microsoft.com/Forums/en-US/posfordotnet/threads

Do you have .NET 2.0 installed on the system?

Thank you.

In the meanwhile I found the problem.

My Program Setting was on Framework 4.0. Downgrade to 3.5 it works....

Thank you

Excellent. POS for .NET  requires .NET 2.0, thus applications cannot be created higher than 3.51.

Answer 4

You can use POS for .NET with .NET 4.0 but need to set the security model in the config file of .NET 4.0.  POS for .NET uses a security model that has been disabled in .NET 4.0, but otherwise it should work just fine.
