Using existing knowledge

For .NET developers who want to start building native mobile applications, it is easier to just learn the APIs for the new platforms than it is to learn programming languages and APIs for both old and new platforms. 

Similarly, organizations that want to build native mobile applications could use their existing developers with their knowledge of .NET to develop applications. Because there are more .NET developers than Objective-C and Swift developers, it would be easier to find new developers for mobile application development projects.
