Steps To Reproduce

Create an blazor webassembly project.

Csproj file:

<Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">

    <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
        <Nullable>enable</Nullable>
        <ImplicitUsings>enable</ImplicitUsings>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="6.0.9" />
        <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer" Version="6.0.9" PrivateAssets="all" />
    </ItemGroup>

    <ItemGroup>
      <EmbeddedResource Update="MyResource.resx">
        <Generator>ResXFileCodeGenerator</Generator>
        <LastGenOutput>MyResource.Designer.cs</LastGenOutput>
      </EmbeddedResource>
    </ItemGroup>

    <ItemGroup>
      <Compile Update="MyResource.Designer.cs">
        <DesignTime>True</DesignTime>
        <AutoGen>True</AutoGen>
        <DependentUpon>MyResource.resx</DependentUpon>
      </Compile>
    </ItemGroup>

</Project>

Program.cs file:

using System.Globalization;
using BlazorApp1;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Microsoft.JSInterop;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
var app = builder.Build();
var js = app.Services.GetService<IJSRuntime>();

var culture = new CultureInfo("pl-PL");
await js.InvokeVoidAsync("alert", MyResource.ResourceManager.GetString("Value", culture));

Create resource file MyResource.resx:

<?xml version="1.0" encoding="utf-8"?>

<root>
    <xsd:schema id="root" xmlns="" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
        <xsd:element name="root" msdata:IsDataSet="true">

        </xsd:element>
    </xsd:schema>
    <resheader name="resmimetype">
        <value>text/microsoft-resx</value>
    </resheader>
    <resheader name="version">
        <value>1.3</value>
    </resheader>
    <resheader name="reader">
        <value>System.Resources.ResXResourceReader, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>
    </resheader>
    <resheader name="writer">
        <value>System.Resources.ResXResourceWriter, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>
    </resheader>
    <data name="Value" xml:space="preserve">
        <value>MyDefaultValue</value>
    </data>
</root>

Create MyResource.pl-pl.resx file:

<root>
    <resheader name="resmimetype">
        <value>text/microsoft-resx</value>
    </resheader>
    <resheader name="version">
        <value>1.3</value>
    </resheader>
    <resheader name="reader">
        <value>System.Resources.ResXResourceReader, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>
    </resheader>
    <resheader name="writer">
        <value>System.Resources.ResXResourceWriter, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>
    </resheader>
    <data name="Value" xml:space="preserve">
        <value>MyPolishValue</value>
    </data>
</root>

Thanks for contacting us. Please note, that satellite assemblies are not loaded automatically, and that may be what you're missing here. You can learn more about how to configure localization by following our docs at https://learn.microsoft.com/en-us/aspnet/core/blazor/globalization-localization?view=aspnetcore-6.0&pivots=webassembly#localization

[kamilos-dev]

It won't work anyway. My app: https://github.com/szyn33k/Blazor-sample-app

Please compile it and check. @mkArtakMSFT
