Using resource files

Our minimal API now supports globalization, so it can switch cultures based on the request. This means that we can provide localized messages to callers, for example, when communicating validation errors. This feature is based on the so-called resource files (.resx), a particular kind of XML file that contains key-value string pairs representing messages that must be localized.

Note

These resource files are exactly the same as they have been since the early versions of .NET.

Important note

Unfortunately, Visual Studio Code does not provide support for handling .resx files. More information about this topic is available at https://github.com/dotnet/AspNetCore.Docs/issues...
