• #13: Filters are used to handle cross cutting concernsFilter types:Action filters run before and after invoking an actionAuthorization filters run before model binding and are specifically for authorizing the userException filters handle generating responses for error cases in a centralized wayFilters can be configured globally, per controller, or per action as an attribute
• #14: Talk about Exception Filter. Create sample filter to the pipeline and show it
• #15: Simple types: Route data, query parametersComplex types Configured MediaTypeFormatters are used to deserialize the request body based the content type JSON, XML and form-url-encoded supported out of the box.
• #16: http://blogs.msdn.com/b/jmstall/archive/2012/04/16/how-webapi-does-parameter-binding.aspxIf the parameter has no attribute on it, then the decision is made purely on the parameter’s .NET type.“Simple types” uses model binding. Complex types uses the formatters. A “simple type” includes:primitives, TimeSpan, DateTime, Guid, Decimal, String, or something with a TypeConverter that converts from strings.You can use a [FromBody] attribute to specify that a parameter should be from the body.You can use a [ModelBinder] attribute on the parameter or the parameter’s type to specify that a parameter should be model bound. This attribute also lets you configure the model binder.  [FromUri] is a derived instance of [ModelBinder] that specifically configures a model binder to only look in the URI.The body can only be read once.  So if you have 2 complex types in the signature, at least one of them must have a [ModelBinder] attribute on it.Differences with MVCHere are some differences between MVC and WebAPI’s parameter binding:MVC only had model binders and no formatters. That’s because MVC would model bind over the request’s body (which it commonly expected to just be FormUrl encoded), whereas WebAPI uses a serializer over the request’s body.MVC buffered the request body, and so could easily feed it into model binding. WebAPI does not buffer the request body, and so does not model bind against the request body by default.WebAPI’s binding can be determined entirely statically based off the action signature types. For example, in WebAPI, you know statically whether a parameter will bind against the body or the query string. Whereas in MVC, the model binding system would search both body and query string.
