Blazor WebAssembly 无法从 class 库加载资源文件

Question

I'm currently working on a Blazor WebAssembly Asp.NET hosted in .NET Standard 2.1.

I try to load resources files from a separate .NET Standard 2.1. C# Class library.

Unfortunately I always get the following error:

"Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Could not load type of field 'MyNamespace.Footer:k__BackingField' (0) due to: Could not load file or assembly 'MyNamespace.Resources, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies."

1. My.resx files are set to Access Modifier: Public and look like this in the properties tab:

My project structure looks like this:

• MyNamespace.BlazorApp.Client
• MyNamespace.BlazorApp.Server
• MyNamespace.BlazorApp.Resources

I load the resources like this:

2. MyNamespace.BlazorApp.Client:

In my Program.cs Main Method I set the current culture like this:

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("en-US");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-US");

and I add the Localization service:

services.AddLocalization();

Further on in a.razor page where I want to use the culture setting I inject the Localization service:

@inject IStringLocalizer<Translations> Translations

3. MyNamespace.BlazorApp.Server

Here I simply load the project reference to my resources project. I don't use the.resx in this project.

Do you know how to load resources from an external .NET Standard 2.1. C# Class library into a Blazor Wasm project?

Answer 1

The error comes from a name clash, the project can be compiled but not loaded.
I know a way to get it working, I'm not sure is this is the only or best way.

1. Rename your resx project to MyNamespace.BlazorApp.Translations
2. Make sure there is a public class Translation in the root (no 's')
3. Make a Folder called Resources in the Translations project
4. Add Translation.resx, Translation.es.resx etc to that folder
5. Change the config to builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");

Resources is a default name at several places, not a good idea to name your own project the same. The ResourcesPath seems to be required, I don't know what the defaults are.
