Describe the bug
While upgrading our applications to net core 3 we noticed that none of our tag helper libraries written in core 1.x work on net core 3. Updating them to asp net core 2.2 version seems to fix the problem. Did something changing in how tag helpers are resolved or is this a bug?
To Reproduce
- Checkout repro
- Run
master
branch - Email tag helper is not being run
- Checkout and run
working
branch which uses 2.2 packages - Email tag helper is run
Expected behavior
1.x version tag helpers referenced from net core 3 are discovered and run
