What are the differences between WebAPI and WebAPI 2 [closed]

What are the MAIN differences (things I should be concerned about) between WepApi and WepApi2 that now ships with Visual Studio 2013?

Solution 1:

Major new features are,

1. AttributeRouting
2. OWIN self host
3. IHttpActionResult
4. CORS
5. HttpRequestContext

I had the same question and found simple article about this, here.

Solution 2:

In addition to the features mentioned by iJay

6. Testability

7. ODATA Improvements

8. Filter Overrides

9. ByteRangeStreamContent

We can differentiate web api and web api2 by using above features.

Solution 3:

WebAPI and WebAPI 2

Actually WebAPI 2.0 is enhanced feature of WebApi there is no difference between this two. In version 2.0, the Web API framework has been enhanced to support the following features:

• IHttpActionResult return type
• A new Routing Attribute
• Support for Cross-Origin requests using CORS
• Securing ASP.NET Web API using OAuth 2.0
• Support for $expand, $select in OData Service
