Captive Dependency - ValidateOnBuild not working

[rahman3593]

I was injecting scoped service in singleton service as shown in the above code in image. and I want the solution build to be failed because I have set the ValidateOnBuild property to true. But the build happens successfully.

Note: But when I try to run the application after build it is throwing error as below.

The same happens when tried to inject transient service into singleton as well.

By build it means when the service container is built when BuildServiceProvider() is called - it doesn't mean when you compile the application with dotnet build. It's behaving correctly by throwing when you run the application and the dependency graph is validated.
