app.config

I had to migrate a .NET 3.5 to 4.0 but some dll's were not loading, after googling I found that creating an app.config would solve it:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" />
  </startup>
</configuration>

I would like to setup these options without using configuration files, is it possible?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
