This is an API that stores any type of files. It also store basic information about the file, that basic information can be updated. This can be useful if you planning to create a project using microservices and you need service to store files.
Install MongoDB and have dotnet development environment ready (i.e Visual studio). You must install dotnet core 2.2. You should be ready to run project from visual studio and swagger page will give you nice view of endpoints.
Feel free to improve this service API and create pull requests!
