2. Create the backend solution

[michalusio]

We want to create a Visual Studio solution in the Backend folder.

Specifically, the structure should look like:

Backend

Backend.sln ...other files

To do so, first create and checkout a new branch (you can call it something like "backend-setup" or however you like). Then, you want to open Visual Studio, select "Create a new project", and go through the whole process. You should select:

• "ASP.NET Core Web API" as the type of the project
• the Backend folder as the root of the solution
• .NET 8.0 as the framework
• No authentication
• No HTTPS support
• Enable Docker (Linux as the OS)
• Enable OpenAPI support
• Top-level statements doesn't matter, we can go either
• Use controllers

After creating the solution, do not forget to commit the changes and create a PR to the master branch.

I committed a new branch as I didn't read the issue correctly.
