.NET Core 3.0 preview8 ?

See original GitHub issue

Hi there,

I’ve tried to upgrade my asp.net core 2.2 application to asp.net core 3.0 preview8 and having an issue similar to #376

I did try with asp.net core 3.0 preview7 and had the same issue Just wondering if this should be working?

Using version 4.0.180

There was a breaking issue (namespace changes in System.Text.Json) between preview 7 and preview 8.

I’ve just pushed a new 4.1.0-preview.21 build to MyGet - see if that resolves your issue?

I’m going to close this our since it’s available, but once 3.0 ships (should be Monday) I’ll follow-up quickly release a MiniProfiler build depending on non-preview packages for 3.0.
