[TomGathercole]

Is there an existing issue for this?

Describe the bug

When adding assets to the wwwroot folder using <Content Link=... />, they are correctly fingerprinted and recognized through @Assets, but they return blank content:

This does work correctly after publishing

Expected Behavior

Assets added through <Content Link=.../> are fingerprinted and the correct content is returned

Steps To Reproduce

Repro added here:

@TomGathercole thanks for contacting us.

I wasn't able to reproduce this with the 10.0 nightly build.

What SDK are you using?

[TomGathercole]

Hi @javiercn, thanks for the quick feedback. We're currently using SDK version 9.0.304. I will find some time to test on the latest nightly

[TomGathercole]

I've tested this on both 10.0.100-preview.2.25164.34 and 10.0.100-rc.1.25451.107. Did you need to make any changes to the repro itself, or does this work as-is with the latest SDK?

@TomGathercole thanks for the additional details.

Did you clean the bin/obj folders after updating the SDK?

Is there any special character in your path? (spaces or similar)

[TomGathercole]

Hi @javiercn ,

I've tried cleaning the bin and obj folders, as well as cloning the repo to an entirely new folder, and I'm still seeing the same issue. There are no special characters including space in the project path.

Just to clarify - I'm able to reproduce the issue by debugging from visual studio, and when running with dotnet run --project contentlinkrepro. When published, the project works correctly
