Why aren't resx cultures found in unit tests?

Question

I have built-in string resources in my .NET 4.0 project: Strings.resx and Strings.de.resx.

In the production code , the correct localized strings are retrieved, depending on the value of Strings.Culture:

Strings.Culture = new Culture("de"); string deString = Strings.Welcome; // 'Willkommen' Strings.Culture = new Culture("en"); string enString = Strings.Welcome; // 'Welcome' 

But in my unit test code (using MSTest), the strings from "Strings.de.resx" never return - I only get strings from Strings.resx, regardless of whether the values ​​are Strings.Culture or Threads.CurrentThread.CultureUICulture .

Does anyone help?

Ok, I was able to reproduce this problem. First of all, try disabling the deployment. Go to the "local.testsettings" section and uncheck "Deployment → Enable Deployment". When this flag is set, VS does not seem to deploy satellite assemblies for me. If you need a deployment item, use DeploymentItemAttribute:

 [DeploymentItem( @".\YourProject\bin\Debug\de\YourProject.resources.dll", @".\de\")] 

or use the same Deployment tab to select the appropriate satellite assemblies.
