configuration - custom section in app.config throws error in c# -


// winconfiguration.cs

using system; using system.configuration;  namespace banana.common {     public class winconfiguration : configurationsection     {         public readonly static banana.common.winconfiguration settings             = (banana.common.winconfiguration)system.configuration.configurationmanager.getsection("banana");          [configurationproperty("connections")]         public connectionscollection connections         {             { return (connectionscollection)this["connections"]; }         }          [configurationproperty("cryptography")]         public cryptographycollection cryptography         {             { return (cryptographycollection)this["cryptography"]; }         }     } }

// app.config

<?xml version="1.0"?> <configuration>     <configsections>         <section name="banana" type="banana.common.winconfiguration"/>     </configsections>     <banana>         <connections>             <add name="sqlserver2008" connectionstring="" providername="system.data.sqlclient" priority="100" />         </connections>         <cryptography>             <add type="des" value="12345" />             <add type="tripledes" value="12345" />         </cryptography>     </banana>     <startup>         <supportedruntime version="v4.0" sku=".netframework,version=v4.0"/>     </startup> </configuration>

it used work in web.config perfectly. changed class name. here web.config , custom configuration class.

// webconfiguration.cs

using system; using system.configuration;  namespace banana.common {     public class webconfiguration : configurationsection     {         public readonly static banana.common.webconfiguration settings = (banana.common.webconfiguration)system.web.configuration.webconfigurationmanager.getsection("banana");          [configurationproperty("connections")]         public connectionscollection connections         {             { return (connectionscollection)this["connections"]; }         }          [configurationproperty("cryptography")]         public cryptographycollection cryptography         {             { return (cryptographycollection)this["cryptography"]; }         }     } }

// web.config

<?xml version="1.0" encoding="utf-8"?> <configuration>     <configsections>         <section name="banana" type="banana.common.webconfiguration"/>     </configsections>     <banana>         <connections>             <add name="sqlserver2008" connectionstring="" providername="system.data.sqlclient" priority="100" />         </connections>         <cryptography>             <add type="des" value="12345" />             <add type="tripledes" value="12345" />         </cryptography>     </banana> </configuration>

it works fine webconfiguration.cs , web.config. winconfiguration.cs , app.config, gives me error "the type initializer 'banana.common.winconfiguration' threw exception.". can fix error me?

i think have specify assembly name (the name of exe or dll) configuration class resides:

<section name="banana" type="banana.common.winconfiguration, your_assembly_name"/>

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
