The Capstone

Localization in Wisej.NETModule 7The samples are ready before the course is: the module outline is on learnwisej.com, and the lessons, the knowledge checks and the hands-on labs follow when it launches — free, with an AI tutor in every lesson.

See the outline

A LocalizationService that is the only place the application touches a ResourceManager or a CultureInfo, with Text, Date, Number and Currency and a documented missing-key policy. A Ticket domain model that exposes a TicketStatus the UI maps to a localized caption. A pseudo-localized pass that found real hard-coded strings in this build. And a QA matrix the application can run on itself. This folder is the complete application at the end of the course.

Browse this folder on GitHub

Or clone it: git clone https://github.com/iceteagroup/LearnWisej-Samples.git — then open GlobalDesk.slnx in Visual Studio and press F5.

Run it

cd "Localization in Wisej.NET Course/Module 7/GlobalDesk"
dotnet run -f net10.0 --urls http://localhost:6107

Open http://localhost:6107, or go straight to http://localhost:6107/?lang=qps-ploc.

What to try

Action	Expected result
Press Run the QA matrix under any culture	One line covering the fallback chain, the three formats, RTL, a probe key, the published culture folders and the missing keys collected this session.
Run it under qps-ploc	Ticket.Waiting -> "Waiting on customer" and No missing keys this session. Read both together - that is the lesson.
Look at the tickets grid under each culture	The status column is a localized caption; the date and the amount are formatted. The reference never changes - it is an identifier.
Switch culture with the grid on screen	The grid is rebuilt. Its cells hold formatted text, so it cannot be left alone.
Set LocalizationService.DevelopmentMode = false	A missing key renders as the bare key instead of [Key], and is still recorded.
Check the output folder	ar, de, it, qps-ploc. English is the neutral file and correctly has no folder.

The finding this module is built around

Ticket.Waiting is deliberately absent from the pseudo-locale. The QA run reports the caption in plain English and says "No missing keys this session" - both true at once. GetString walked the fallback chain, found the neutral value and returned it, so the policy never fired.

A missing-key policy and pseudo-localization catch different defects. The policy catches a key the code asks for that nobody wrote. Pseudo-localization catches a key that exists in the neutral file but is missing from a translation, because that falls back silently and looks deliberate. Neither sees the other's defect, so run both.

The same pass found two genuinely hard-coded column headers in this build, Reference and Status, unbracketed beside a screen of bracketed captions. They now have keys in all five files.

Notes for anyone extending the service

• Everything reads Application.CurrentCulture per call. No static state, ever - Module 4's note has the two-user failure in full.
• Currency formats; it does not convert. An amount in euros shown to a US session renders as $1,850.75 - right shape, wrong currency. Multi-currency means the currency is part of the data.
• Pass the culture to string.Format as well as to each ToString. Without it, string.Format uses the thread's culture.
• Ticket.ResourceKeyFor is a switch, not "Ticket." + status. Concatenation compiles whatever you rename the enum to and fails at run time; the switch fails at the point of the change.
• The tickets grid is not data-bound to the model on purpose. Binding would show the enum name and the invariant ToString of the date, which is the defect this module is about.
• <NeutralLanguage>en</NeutralLanguage> is what declares that English needs no satellite. Without it the build produces an en folder nobody uses.
