Exception thrown from StaticContentProvider._manifestProvider

[b-straub]

Describe the bug

The commit 2d5da9c triggers a long standing and never fixed dotnet extensions bug:
ManifestEmbeddedFileProvider not working when Resources.resx in same project

To Reproduce

Run the sample app from "\src\Components\WebView\Samples\BlazorWinFormsApp"

Exceptions (if any)

InnerException = {"Invalid manifest format. 'ResourcePath' must contain a text value. ''"}
Message = "The type initializer for 'Microsoft.AspNetCore.Components.WebView.StaticContentProvider' threw an exception."

@b-straub thanks for contacting us.

@Eilon we might have missed that. We need to mark the embedded resource with ExcludeFromManifest=true
