Unity built for WebGL embedded into a Blazor application won't instantiate properly

Upon trying to run

Code (JavaScript):

1.  UnityLoader.instantiate("unityContainer", "Build/TWI.json");

I receive this message:


The screen seems to have at least partially loaded the unity box, and I can see this in the console:



How do I make sure the "UnityModule" is loaded before I instantiate my container? Or is there a way for me to call "loadModule" from UnityLoader directly?

Since this is a Blazor web app launched via IIS, the mime types are configured in the Startup, where I added the following code:

Code (CSharp):

1. app.UseResponseCompression();
2.  
3. var provider = new FileExtensionContentTypeProvider();
4. provider.Mappings.Add(".wasm", "application/octet-stream");
5. provider.Mappings.Add(".unityweb", "application/octet-stream");
6.  
7. app.UseStaticFiles(new StaticFileOptions
8. {
9.     ContentTypeProvider = provider,
10. });

One thing I noted was the lack of the ability to add a "remove file extension" option via the configuration. But if there isn't a web.config, how/where do I do that?

 

I've fixed the problem. The issue was that I had the Build files inside of the wwwroot folder on the Client portion of Blazor instead of the Server portion, and that I was running in IIS Express; so the fix was to not run IIS express, and to move the Build files, as well as deleting the IndexDB cache in my browser.
