Hi Doug,
From your descirption, you've defined a custom configuration sectionhandler and use it in your .net application(the class also be compiled to
the main exe assembly), this worked well on local drive but encounter some
assembly loading issue when deploy on a remote share, correct?
As for this problem application, so far the deployed application folder
should only contains two files:
** the application's main exe assembly
** the app.config (exe.config)
correct? I have performed a local test which is a console application use a
custom configuration section handler( defined in the main assembly). After
I deploy the application to a UNC share folder and access from another
box(windows 2003), here are what I got based on the testing:
1. If I grant the unc share folder "FullTrust" through URL evidence, then
the application can work without problem
2. If you do not grant the entire share folder "FullTrust", and only grant
the main assembly "FullTrust" by strong-name evidence, you need to make
sure you always use the strong-name signature(include public key token) in
any configuration setting or code which reference the assembly. For
example, in the app.config's custom configuration section register section,
you need to use full assembly name(with publickey token) when declare the
custom section handler type (as below);
===============
<configuration>
<configSections>
<sectionGroup name="myCustomGroup">
<section
name="myCustomSection"
type="CASSection.CASSection, CASSection, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=04e2c2d696067136"
allowLocation="true"
allowDefinition="Everywhere"
/>
...................
===========================
If you use a private assembly name, it will also cause problem.
You can have a try on your side to see whether this is the cause. If you
have any other finding, please feel free to post here.
