Pos for .Net not Framework 4.0 compatible ?

Question

When i create an instance of the POSExplorer, i got en error cause this one uses CAS, which is no longer in the .Net Framework.

I found some hints saying to set this

<configuration>
   <runtime>
      <NetFx40_LegacySecurityPolicy enabled="true"/>
   </runtime>
</configuration>

in the .Config file.

but they dont work. My Application is delivered withot an config file.

Is there any other solution ?

Answer 1

I think you have to install .Net 3.5 before 4.0. It seems that 4.0 does not include all from previous versions.

Answer 2

Thanks for your tip, but Framework 3.51 is installed on my machine.

Does anybody got POS .Net running on Framework 4.0 ?

Answer 3

What is the OS version? If the .config file will help why you do not add it to the installation?

Answer 4

Operating System is windows 7.

Yes, i can add it to the config file, but i must change a complex installation procedure. ( we are using an automated distribution system)

If possible, i would like to avoid this

Hi,

I believe this is a known problem and there isn't another solution. Technically it is the fault of the .Net 4 team since they changed the security model (CAS) and now require these config file entries to run older code... however they only real solution is for the Pos .Net team to provide a new release compiled against .Net 4 to fix the issue. So far no such update has been forthcoming, but I still hold hope that they will release one in the next 12 months or so.

Yort,

I know this is an old thread, but has there been any update from the POS team? Any hints of an updated version coming any time soon?

Thanks!

Hi,

Sadly I haven't seen or heard of any updates to Pos .Net at all since this issue was raised. It distressing.
