There may be an issue here with the Linux images we’re using – we will investigate and follow-up on this.
I’ve hit a very similar issue, but mine ends up with a time out.
I moved exactly the same deployment to a Windows function, and it worked absolutely fine. Moved it back to a Linux function, and Boom! Can’t find Microsoft.AspNetCore.App version 5.0.0.
Looks like something screwy is going on with the Linux hosts at the moment.
Hey all – we’re investigating this now – can those of you hitting this issue confirm that you’re trying to do this in your project file?
<FrameworkReference Include="Microsoft.AspNetCore.App" />And if you have an exact repro project file somewhere, that’d be helpful.
