c# - Asp.Net Core localization not working using VSCode -

i'm using vscode create asp.net core api. i'm trying day figure out how make localization work no results. when exact same thing in visual studio 2015 community edition works fine. not vscode...

so created following super simple project simplest structure in vscode:

i'm using postman send http on http://localhost:5000/app. result json this:

{   "name": "test_value",   "value": "test_value",   "resourcenotfound": true } 

the vs community project simillar:

the result json (the right one):

{   "name": "test_value",   "value": "this test value!",   "resourcenotfound": false } 

could figure out why not working inside vscode? in both cases running kestrel, both projects complile fine, both have exact same following source code. problem there in windows , in linux development enviroment. drives me crazy!

i figured out!

the problem name of project's folder different root namespace! project's folder name my-app. name picked github repository. my-app name of project's folder created when cloned repository and, also, name of produced assembly (my-app.dll) inherits it's name project folder. however, root namespace picked myapp.

the reason had no problem vs community when created project picked solution name myapp , project's folder name , root namespace too!

i not sure if actual problem folder's name or name of produced assembly. guess it's assembly name.

so, bottomline, localization work the project's folder name (that name of produced assembly too) must same root namespace!
