Hello, I upgraded my project to the latest version from v8.7 and I ran into this issue below.
To make sure I did not do anything wron with my merge, I started fresh with the latest downloaded:
- Changed connection string in Web.Mvc project
- Ran migration
- Yarn/NPM commands to prepare solution
- Built the solution
- Ran the solution: no build errors. All 15 projects for Web.sln ran without issues.
- Getting stuck with the exception below.
An error occurred while starting the application. ComponentNotFoundException: No component for supporting the service HealthChecks.UI.Core.Data.HealthChecksDb was found Castle.MicroKernel.DefaultKernel.Castle.MicroKernel.IKernelInternal.Resolve(Type service, Arguments arguments, IReleasePolicy policy, bool ignoreParentContext)

I solved this issue by basically reverting to the previous version of HealthCheck package AspNetCore.HealthChecks.UI v 3.0.11 and deleted the other one completely. I am not sure what was the added benefits to upgrade and/or if the new package was tested prior to releasing v9.0.0

Hi,
Did you also add a reference to https://www.nuget.org/packages/AspNetCore.HealthChecks.UI.Client ?
Could you try this with a brand new 9.0 Demo project ? We couldn't reproduce your problem. It might be related to your upgrade process.

Hi ismcagdas, I lilterally downloaded my project from your site, ran yan/npm restore commands, changed my connection string and ran the project.
I am running it on Windows 10, VS2019.
I have not tried it using a new project demo. I am not sure how that would solve my problem. However, like I said, I downgraded back to previous version and it worked.
Do you see any benefits in the latest upgrade for healthchecks?
