I have a react app in VS that i compile using npm run build . It compiles correctly.
Then i publish the appp to Azure using the publish functionality in VS.

But when i publish and i try to run the app it says

  Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Now the resource is /login/checkuser. This is a login controller in the app with an action called checkuser.
Am i meant to see the compiled dll’s for the controllers in the website because when i browse it , none of them are there ?

How can i get this to deploy all required files ?
