Net Core: Difference between .SetBasePath and .UseContentRoot in Startup.Cs

What is the difference between .SetBasePath and .UseContentRoot in Startup configuration?

var configuration = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json")
            .Build();

How can I use IConfiguration from my integration tests?

For dotnet6/7 in 2022 with top-level statements, UseContentRoot is not available, just set the current directory before WebApplication.CreateBuilder works for me.

var dllFolder = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
Directory.SetCurrentDirectory(dllFolder);

var builder = WebApplication.CreateBuilder(args);
builder.Configuration.SetBasePath(dllFolder);

SetBasePath is an extension method for IConfigurationBuilder, which sets the path to use when locating configuration files:

Sets the FileProvider for file-based providers to a PhysicalFileProvider with the base path.

For example, when locating the appsettings.json file you've specified in your question, it will look in the path retrieved using Directory.GetCurrentDirectory()

UseContentRoot is an extension method for IWebHostBuilder, which sets the contentRoot key for the Web Host:

This setting determines where ASP.NET Core begins searching for content files, such as MVC views.

The default value used for the contentRoot key is:

[...] the folder where the app assembly resides.

This means that, for a typical setup, the path for both will end up being the same, but this is not a requirement.
