Ant Forgery error on first AppHost run after upgrading to 9.0

Describe the bug

On the first run of an App Host after upgrading from 8.2 to 9.0.0-preview.4.24477.2 the error logs immediately spewed an error about a invalid Anti Forgery token. This error goes away on subsequent runs, but it's a bit unnerving to get the error.

For what it's worth, a similar antiforgery error can also be reproduced if you downgrade from from 9.0 to 8.2 on the first run after the downgrade and doesn't appear on subsequent runs.

Expected Behavior

No error to be reported.

Steps To Reproduce

1. Have an AppHost using Aspire 8.2
2. Run the AppHost
3. Upgrade to Aspire 9.0.0-preview.4.24477.2
4. Run the Upgraded AppHost
