Static file, multiple locations

[ventureaaron]

[EDIT by guardrex to update the metadata]

Description

In the final blazor example for serving from multiple locations, the compiled css file seems to get lost (appname.styles.css). Debugging the webrootfileprovider seems to indicate the culprit is the Microsoft.AspNetCore.StaticWebAssets.ManifestStaticWebAssetFileProvider dropping out when we replace the webrootprovider with the compositeProvider in the example.

I worked around this with this below, but it's almost certain to not be the proper way:

var secondaryProvider = new PhysicalFileProvider(
    builder.Configuration.GetValue<String>("serverDir:HomePath")!);
var oldProvider = app.Environment.WebRootFileProvider;
var compositeProvider = new CompositeFileProvider(oldProvider, secondaryProvider);
app.Environment.WebRootFileProvider = compositeProvider;

Cheers on fantastic documentation! Really appreciating all the efforts.

Sorry that it didn't work out the way that I expected. Our normal workflow would've been to get an answer on the product unit's repo that I could then work into the Static Files article here if it turns out to be a special case for Blazor apps. Your issue was transferred back over here. I sent an email to Artak to ask him what the plan is for this issue. I'll comment back here after he lets me know how this one is going to be handled.

[ventureaaron]

I probably did something wrong. Let me know if I need to resubmit anything or how else I can help.

Let's wait for Artak to respond to my email. I'll report back when I hear from him.

[guardrex]

There was no response to my email.

I'm going to see if I can repro this, and I'll send Artak another email to ask how he wants to proceed. His transferred issue (your PU issue) is now a duplicate here, and I don't think Javier sees the pings from this repo ... i.e., your issue has "gone into a black hole" at the moment 😆. I'll see if I can get some action going on this.

[guardrex]

Confirmed that this is only a problem for BWAs (Blazor Server works with the approach in the main doc set article).

Your approach ...

var secondaryProvider = new PhysicalFileProvider(
    Path.Combine(builder.Environment.ContentRootPath, "MyStaticFiles"));
app.Environment.WebRootFileProvider = new CompositeFileProvider(
    app.Environment.WebRootFileProvider, secondaryProvider);

... ✨ Just Works!™ ✨ ... and seems fine with me as a suggested alternative.

I'm going to close the transferred issue and work from this issue.

I'll take the following actions ...

• Add a section to the Blazor Static Files article for this for 8.0 or later targeting BWA development.
• Place a remark in the main doc set's Static Files article section with a cross-link to the new guidance.
