Health Check issue with Microsoft.Extensions.Diagnostics.HealthChecks 7.0.0 running on net6.0

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Having found two “fixes” already this is more a should-it-be-like-this?

Health checks are not working if the package Microsoft.Extensions.Diagnostics.HealthChecks version 7.0.0 is added and you are running .NET 6.

The health endpoints return 500 Internal Server Error and never enter construcor or CheckHealthAsync() method of a custom health check.

Does not occur if:

• Only Microsoft.Extensions.Diagnostics.HealthChecks.Abstractions is used
• Runtime is net7.0

Expected Behavior

Not for health endpoints to return 500 Internal Server Error.

Steps To Reproduce

Small example here: https://github.com/Hoaas/HealthCheckIssue

Created with dotnet new webapi. Added packages <PackageReference Include="Microsoft.Extensions.Diagnostics.HealthChecks" Version="7.0.0" /> <PackageReference Include="Microsoft.Extensions.Diagnostics.HealthChecks.Abstractions" Version="7.0.0" />

And changed to <TargetFramework>net6.0</TargetFramework>. Added sample health check class from from https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/health-checks?view=aspnetcore-7.0#create-health-checks

Starting and attempting to call /healthz returns 500.

Anything else?

.Net 6 assembly utilizing Package v 6.0.13 This issue just “appeared” one day. At what point does Microsoft go back to being a professionally organized company (instead of a gaggle of independent developers?)?? You’re starting to get badmouthed pretty regularly among those of us who didn’t hang our hats on your tech. I believe you have one of the best RAD platforms, but you’re ruining it with a lack of coordination. There is absolutely NO reason for this error in .Net 6 except irresponsible coding. - NO EXCUSE!

Using 7.0.x packages isn’t supported with .NET 6: https://github.com/dotnet/aspnetcore/issues/45149#issuecomment-1320517662
