troubleshooting sudden ArgumentException at TryInterpretSingletonAndUnwrapContainerException

What version are you using?
Could you try DryIoc.Microsoft.DependencyInjection v8.0.0-preview-01?

I'm using version 6.2.0.

I finally figured out the culprit. In my Startup.cs 's ConfigureServices I have this:

services.AddServerSentEvents(options =>
{
    options.ReconnectInterval = 5000;
    options.KeepaliveInterval = startupConfig.SseKeepAliveInterval;
    options.KeepaliveMode = startupConfig.SseKeepAliveInterval > 0 ? ServerSentEventsKeepaliveMode.Always : ServerSentEventsKeepaliveMode.Never;
});

That's based on a package

When startupConfig.SseKeepAliveInterval was 0, then problem would occurr, when it was > 0, no problem. AddServerSentEvents is an extension that comes from the Lib.AspNetCore.ServerSentEvents nuget package.

I'll give the preview a try - just found it very confusing that it errors out in what seems to be DryIoc.

@ssteiner You are getting the errors because it resolves (creates or gets) service via DryIoc.
The service is Singleton based on the stack trace.
DryIoc has done its work and is calling to the service constructor or factory method.
A service may fail its creation, usually wrapping the original exception in the TargetInvocationException.
DryIoc will unwrap and re-throw the exception, trying to preserve a stack trace.
