AspNet Core 5.0.4 seems incompatible with earlier Net 5 runtimes

Describe the bug

AspNet Core 5.0.4 seems incompatible with earlier Net 5 runtimes eg, 5.0.3

To Reproduce

1. Ensure below runtimes are installed. .Net core - 5.0.3 AspNet Core - 5.0.4 (Shared framework) We also have Net Desktop 5.0.3 however that seems to be optional for the bug.

2. Create a simple AspNet api from the template. WeatherForecast example would do.

3. Build the api project.

4. Run the generated <api>.exe or run the <api>.dll using dotnet tool.

Result: The error shows It was not possible to find any compatible framework version The framework ‘Microsoft.NETCore.App’, version ‘5.0.4’ was not found.

• The following frameworks were found: 2.1.24 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] 3.1.11 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] 5.0.1 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] 5.0.2 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] 5.0.3 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

Please note this issue goes away if I manually install .Net Core 5.0.4

However since this is just a patch should this need a .Net Core runtime upgrade to version 5.0.4 as well? Should we expect this behavior on any further patch/minor updates too?

Exceptions (if any)

The bundle is helpful for upgrades, however since we use all 3 runtimes, would we also need to ensure that desktop runtime is also upgraded along with AspNet since all will depend on .Net runtime at the core of it? I would try and test the scenario by this weekend. I believe the confusion here is mainly due to it being a patch version but would be happy to understand the thoughts on it?

If you’d like to install all 3, we recommend you install the SDK, which carries with it all 3 runtimes. You can also find that on the left side of the page I linked above.
