Exception at startup with latest SDK

See original GitHub issue

Starting an ASP.NET application targeting netcoreapp5.0 with recent SDKs (since last week between Wednesday 13th and Thursday 14th) triggers:

Job failed at runtime:
Unhandled exception. System.IO.FileLoadException: Could not load file or assembly 'System.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)
File name: 'System.Runtime, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

Latest known version to work for me is:


Could repro with at least 5.0.100-alpha1-015731 but I don’t have the list of versions in between to be more precise.
