Hi,
 
I am receiving several errors when I attempt to start my application. The application eventually works but I think the undermentioned errors are causing some errors in the designer.
 
I am using Devforce 2010 6.0.4.0 in a Silverlight application.
 
My application is split into 4 projects:
DomainModel (the project containing the domain model)
DomainModelSL (the project containing the linked files to the domain model for use in the SL project)
JTS2 (the Client Silverlight app)
JTS2Web (the Web project)
 
I only have one app.config (in the DomainModel project) and it contains:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="ideablade.configuration" type="IdeaBlade.Core.Configuration.IdeaBladeSection, IdeaBlade.Core, Version=6.0.4.0, Culture=neutral, PublicKeyToken=287b5094865421c0" />
  </configSections>
  <connectionStrings>
    <add name="JTS2Entities" connectionString="metadata=res://*/JTS2Model.csdl|res://*/JTS2Model.ssdl|res://*/JTS2Model.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=localhost\sqlexpress;Initial Catalog=JTS2;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
  <objectServer isDistributed="true" remoteBaseURL="http://localhost" serverPort="80" serviceName="JTS2/EntityService.svc" />
  <ideablade.configuration version="6.00" xmlns="http://schemas.ideablade.com/2010/IdeaBladeConfig">
    <logging logFile="DebugLog.xml" />
    <objectServer remoteBaseURL="http://localhost" serverPort="9009" serviceName="EntityService">
      <serverSettings supportedClientApplicationType="Silverlight" loginManagerRequired="true" sessionEncryptionKey="0FEBFBFF000106E5000c297ebf18" useAspNetSecurityServices="true" />
    </objectServer>
  </ideablade.configuration>
</configuration>
The web app Web.config looks as follows:
<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="ideablade.configuration" type="IdeaBlade.Core.Configuration.IdeaBladeSection, IdeaBlade.Core"/>
  </configSections>

    <remove name="LocalSqlServer" />
    <add name="LocalSqlServer" connectionString="data source=localhost\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=JTS2;" providerName="System.Data.SqlClient"/>
  </connectionStrings>

    <profile enabled="true">

  </system.web>
</configuration>

Other errors are also displayed (I can include them for you if you require) but eventually the application

Please could you help me in identifying why I am getting these errors.

The errors you see are all handled internally, either by DevForce or within the .NET framework.  You'll see these exceptions when debugging in Visual Studio and you've turned on the flag to throw for all exceptions.   These errors are all innocuous, and if you don't want to see them during a debugging session you can turn off the "throw on all exceptions" flag or specifically turn the throw flag off for these exceptions.
