Re: calling fully trusted assembly from partially trusted appDomain

Yes, it is possible to do this (although it does imply a security risk).
The main thing is that the fully trusted assembly needs to Assert the
permission that will be demanded by the underlying framework, perform the
protected operation and then revert the assert.

In many cases, your assembly will also need the
AllowPartiallyTrustedCallersAttribute applied to it.

Hi,

Is it possible to call a fully trusted code that performs actions that the
partially trusted appDomain running code is not allowed to run?

Here is my scenario:
1. create an appDomain which is restricted from writing to a specific
file.
2. I want this appDomain to call another assembly (my assembly) that will
perform the file writing for the partially trusted appDomain.

Although my assembly has full trust on the machine I still get a security
exception when trying to write to the file...

Is there any way of making this scenario work???

Thanks
Shai
