title: Can I deploy a RESTful API with .Net Framework 4.5 on AWS Lambda?
body: <p>I have been trying to anticipate the issues I may face when trying to migrate an existing API developed in .NET framework 4.5 and deployed in an IIS to a serverless architecture based on AWS Lambda.</p>
  
  <p>Currently, the API is divided in: Controller (entry point), service (buz logic) and repository (basically LINQ), and of course some DTO and DAO's, nothing fancy. In addition, I have got some dependencies to external libraries but I don't know if that really matters. </p>
  
  <p>Here is the thing: As I could see when configuring my Lambda, it only accepts .Net Core applications. Ouch! Then, is it necessary to migrate to .Net Core? If it is, can anyone tell me how much development that requires considering my set up?</p>
