[Opensim-dev] .NET 4 Teething Problems

[Zadark Portal]

Included the following with Mantis 6853

Information relating to exception:
An attempt was made to load an assembly from a network location which
would have caused the assembly to be sandboxed in previous versions of
the .NET Framework.

Attachment Manager included in Microsoft Windows attaches security policies
to files downloaded from a network location. Normally this effects only
files
contained in compressed zip format (.zip) though other file types can be
affected depending on the local computer group security policies (thinking
machines registered to a domain though not exclusively)

The effect of the policy can be observed by opening the properties dialogue
for a downloaded file, under the 'General' tab (default) and towards the
lower section of the dialogue an additional button is displayed 'Unblock'.
Click this button and exit the dialogue using the 'ok' button.

This procedure effectively changes all the files within the zip. If however
the
unzipped contents are used prior to the procedure, the each file will
require 'Unblock' to be selected.

Changing this policy would be a significant security reduction, so best
policy is, any file downloaded be inspected using the procedure above.

Issue coming to light now is due to CAS policy changes within .NET 4

It would be useful if people evaluating this procedure reported their
findings.
