FileProviders MvcRazorRuntimeCompilationOptions vs RazorViewEngineOptions

[DiegoStefanon]

Describe the bug

in core 3.rc1 is not working anymore ->
services.Configure<MvcRazorRuntimeCompilationOptions>(opts =>
opts.FileProviders.Add(fp)
);

in core 2.2 was good ->
RazorViewEngineOptions FileProviders.Add was working

Expected behavior

In asp.net core 3 rc1
RazorViewEngineOptions has no more FileProviders property
so using the new one MvcRazorRuntimeCompilationOptions is not working anymore

Thanks

I have discovered that in order to work I have to deactivate other services, ok

I'm experiencing the same problem and couldn't understand your solution. Can it be any clearer?

[DiegoStefanon]

Yes, it does not work anymore as in last net core 2.2 was good ->
RazorViewEngineOptions FileProviders.Add (was working)

In asp.net core 3
RazorViewEngineOptions has no more FileProviders property
so using the new one MvcRazorRuntimeCompilationOptions is not working anymore
very boring and without sense.

In order to work you have to add the CompileOnRuntime and deactivate some functionalities
and activates some tricks... )-):

In past version 2.2 it was working
I'm not understanding why they changed or may be it's a bug ?

Same problem for me after migrating to asp.net core 3.0.
Embedded views not found...

Any workaround ?

Thanks for contacting us, @DiegoStefanon.
This is an intentional breaking change in 3.0, and is documented here: aspnet/Announcements#343

[mkArtakMSFT]

@geotinc we have a separate issue tracking the Embedded Views issue you're facing: #14374

[nfplee]

It looks like AddMvcRazorRuntimeCompilation has been renamed to AddRazorRuntimeCompilation. I cannot comment on aspnet/Announcements#343.

@nfplee as stated in the announcement:

Please use #7647 for further discussions or questions.

Also same problem after migrating from core 2.2 to asp.net core 3.0.
RazorViewEngineOptions has no options.FileProviders property (by design) and using MvcRazorRuntimeCompilationOptions results in embedded views not being found.

[dario-l]

We use FileProviders to pointing out views in different modules. When Project is compiled in Release mode views are copied to the main project. We do not use compilation.

In 3.0 it is not working. Why? Why? Why?

It only works as the views compilation is enabled. Otherwise, he can't see even the paths given by ViewLocationExpanders.
