If I change website configuration through IIS Manager and APPLY changes, then web.config file will loose some values.
For example, I have some custom sections in my web.config and some .net 2.0 configuration sections:
<applicationSettings>
<SC.Sendum.PT200.Properties.Settings>
<setting name="SC_PT200_TscSms_SendSmsService" serializeAs="String">
<value>SOME VALUE</value>
</setting>
</SC.Sendum.PT200.Properties.Settings>
...
</applicationSettings>
if i open IIS Manager and change Default Document for this website and click APPLY. Then web.config will be saved, but values will be lost for some items:
<applicationSettings>
<SC.Sendum.PT200.Properties.Settings>
<setting name="SC_PT200_TscSms_SendSmsService" serializeAs="String">
<value></value>
</setting>
</SC.Sendum.PT200.Properties.Settings>
...
</applicationSettings>
