This solution includes two projects, ClientSideApp and ServerSideApp.

• The ServerSideApp project contains an API controller FilesController, which includes two actions for (1) uploading a file with Multipart form-data, and (2) downloading a file. The ServerSideApp project also contains a web page for uploading a file.

• The ClientSideApp project is a Console application that uploads a *.txt file to the API endpoint in the ServerSideApp, then download the file from the ServerSideApp. The ClientSideApp project demonstrates an example of sending multipart form-data using HttpClient.

The following gif image shows the screen recording of the working demo.
