Serving static .properties file from wwwroot => 404

Hello guys, i try actually to use a worker (https://github.com/mozilla/pdf.js) in my blazor app, worker who need to read some .properties files.

It seem the file are not accessible by default, i always have a 404 error when i try to access it.

How to reproduce :

• create a blazor webAssembly app .net core hosted
• on the wwwroot of the client project, put one test.json and one test.properties file
• launch the app
• open the url https://localhost:xxxxx/test.json => OK
• open the url https://localhost:xxxxx/test.properties=> 404

I try to add a mapping to this extension on the startup as i see on internet

var provider = new FileExtensionContentTypeProvider();
provider.Mappings[".properties"] = "application/octet-stream";
app.UseStaticFiles(new StaticFileOptions { ContentTypeProvider = provider });

• on the startup of the server project : no effect
• on the startup of the client project : it seem i can’t put this code here. I need a IApplicationBuilder on entry point, and on the client side i have a ComponentsApplicationBuilder.

Thanks for your help !

I am sorry, my first solution is for web project. Your is Blazor-Client (WASM).

After looking for awhile, i got workaround on adding new MIME.

The extensions is here BlazorExtensions.cs on project ContentTypeCustom.

oups i didn’t see that sorry !

ok i found what’s happen, i was thinking only your UseClientSideBlazorFile was needed but we really need the original one too. now it works.

thanks for your help, the problem is close for me !
