NET Framework, its culture is determined by the culture of the calling thread. The following example changes the current culture to Portuguese Brazil and launches six tasks, each of which displays its thread ID, its task ID, and its current culture. Each of the tasks and the threads has inherited the culture of the calling thread. For more information, see the "Culture and task-based asynchronous operations" section in the CultureInfo topic. Note that if you set a specific culture that is different from the system-installed culture or the user's preferred culture, and your application starts multiple threads, the current culture of those threads will be the culture that is returned by the GetUserDefaultLocaleName function, unless you assign a culture to the DefaultThreadCurrentCulture property in the application domain in which the thread is executing.
For more information about how the culture of a thread is determined, see the "Culture and threads" section in the CultureInfo reference page.
The CultureInfo. CurrentCulture property is a per-thread setting; that is, each thread can have its own culture. You get the culture of the current thread by retrieving the value of the CultureInfo.
CurrentCulture property, as the following example illustrates. To change the culture that's used by an existing thread, you set the CultureInfo. CurrentCulture property to the new culture. If you explicitly change a thread's culture in this way, that change persists if the thread crosses application domain boundaries.
The following example changes the current thread culture to Dutch Netherlands. It also shows that, when the current thread crosses application domain boundaries, its current culture remains changed.
Changing the culture by using the CultureInfo. Manipulating threads is dangerous because of the security state associated with threads. Making the change to IIS changed web.
So something on my machine is still set to en-GB. If you need to change OS settings, then yes - it is different approach then my snippets. But in case, that your globalization will be set to allow client based culture, then those settings from OS will be overriden in a run-time.

Podcast Making Agile work for data science. Stack Gives Back Featured on Meta. NET Framework prior to. NET Framework, the culture of the calling thread is not part of a task's context. Instead, unless one is explicitly defined, the culture of new threads by default is the system culture.
The following example, which is identical to the previous example except that it lacks the TargetFrameworkAttribute attribute, illustrates this. Because the system culture of the system on which the example executed was English United States , the culture of the task that executes asynchronously on a thread pool thread is en-US rather than fr-FR. NET Framework from. The following example is identical to the previous example, except that it uses the DefaultThreadCurrentCulture property to ensure that thread pool threads have the same culture as the main app thread.
DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture are per-app domain properties; that is, they establish a default culture for all threads not explicitly assigned a culture in a specific application domain.
However, for apps that target. The following example shows that the calling thread's culture remains the current culture of a task-based asynchronous operation even if the method that the task is executing crosses application domain boundaries.
It defines a class, DataRetriever , with a single method, GetFormattedNumber , that returns a random double-precision floating-point number between 1 and 1, formatted as a currency value. A first task is run that simply instantiates a DataRetriever instance and calls its GetFormattedNumber method. A second task reports its current application domain, creates a new application domain, instantiates a DataRetriever instance in the new application domain, and calls its GetFormattedNumber method.
As the output from the example shows, the current culture has remained the same in the calling thread, the first task, and the second task both when it was executing in the main application domain and the second application domain. It is successfully deserialized only in an environment where that Name has the same meaning. The following three examples show why this is not always the case:. If the CultureTypes property value is CultureTypes. InstalledWin32Cultures , and if that culture was first introduced in a particular version of the Windows operating system, it is not possible to deserialize it on an earlier version of Windows.
For example, if a culture was introduced in Windows 10, it cannot be deserialized on Windows 8. If the CultureTypes value is CultureTypes. UserCustomCulture , and the computer on which it is deserialized does not have this user custom culture installed, it is not possible to deserialize it. ReplacementCultures , and the computer on which it is deserialized does not have this replacement culture, it deserializes to the same name, but not all of the same characteristics.
For example, if en-US is a replacement culture on computer A, but not on computer B, and if a CultureInfo object referring to this culture is serialized on computer A and deserialized on computer B, then none of the custom characteristics of the culture are transmitted.
The culture deserializes successfully, but with a different meaning. The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel.
For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. In general, your applications should honor these user overrides.
If UseUserOverride is true and the specified culture matches the current culture of Windows, the CultureInfo uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, and the properties of the NumberFormatInfo instance returned by the NumberFormat property. If the user settings are incompatible with the culture associated with the CultureInfo , for example, if the selected calendar is not one of the OptionalCalendars , the results of the methods and the values of the properties are undefined.
The Spanish Spain culture has two sort orders: the default international sort order, and the traditional sort order. When you instantiate a CultureInfo object with the es-ES culture name, the international sort order is used. When you instantiate a CultureInfo object with the es-ES-tradnl culture name, the traditional sort order is used. When you instantiate a CultureInfo object with the zh-CN culture name, the default sort order is used.
When you instantiate a CultureInfo object with a local identifier of 0x, strings are sorted by stroke count. The following table lists the cultures that support alternate sort orders and the identifiers for the default and alternate sort orders. NET Framework and. NET Core apps. However, UWP apps recognize a single culture. Languages collection. In UWP apps, the current culture maps to the Windows.
Languages collection, which is a global setting. Setting the CurrentCulture or CurrentUICulture property changes the culture of the entire app; culture cannot be set on a per-thread basis. Initializes a new instance of the CultureInfo class based on the culture specified by the culture identifier. Initializes a new instance of the CultureInfo class based on the culture specified by the culture identifier and on a value that specifies whether to use the user-selected culture settings from Windows.
Initializes a new instance of the CultureInfo class based on the culture specified by name. Initializes a new instance of the CultureInfo class based on the culture specified by name and on a value that specifies whether to use the user-selected culture settings from Windows. Gets the CompareInfo that defines how to compare strings for the culture. Gets the culture types that pertain to the current CultureInfo object. Gets or sets the CultureInfo object that represents the culture used by the current thread and task-based asynchronous operations.
Gets or sets the CultureInfo object that represents the current user interface culture used by the Resource Manager to look up culture-specific resources at run time.
Gets or sets a DateTimeFormatInfo that defines the culturally appropriate format of displaying dates and times. Gets the CultureInfo that represents the culture installed with the operating system. Gets the CultureInfo object that is culture-independent invariant. Gets a value indicating whether the current CultureInfo represents a neutral culture.
