Prerequisites

• .NET SDK 10
• SQL Server (LocalDB or Express recommended)
• EF Core CLI tools

Install EF Core CLI tools

The EF Core command-line tools are required to apply database migrations.

dotnet tool install --global dotnet-ef

Setup the project

Install the required NuGet packages: dotnet restore

(Just in case: Update the database connection string in appsettings.json: "ConnectionStrings": { "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=GalleryBlazorDB;Trusted_Connection=True;MultipleActiveResultSets=true" })

Apply the initial database migration (needs to be done only once): dotnet ef database update

Run the application:

dotnet run

At least in my setup, the application runs at http://localhost:5269/ by default.

Pictures

User1 can edit the settings of the picture in the gallery as owner. User1 has made the picture public.

User2 can see the public picture user1 has uploaded, but can't edit it.
