My application compiles successfully but when I try to debug it throws the
above exception on type and then exits. It seems that my application
configuration file has a problem under the Routers section on "link"
sub-section. Here is my code:
app.config:
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="Routers"
type="Energy.Routing.Configuration.RoutingSection, Routing"/>
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
</startup>
<Routers>
<links>
<link name="LAZY" trader="Energy.LAZY.LAZYTrader, Energy.LAZY"
panel="Energy.LAZY.Xaml.LAZYSettings, Energy.LAZY"/>
<link name="FAST" trader="Energy.FAST.FASTTrader, Energy.FAST"
panel="Energy.FAST.Xaml.FASTSettings, Energy.FAST"/>
</links>
</Routers>
</configuration>
