Closed AhmedHemdan21 closed 9 months ago

AhmedHemdan21 commented 10 months ago

I've tried to use this package for the first time,

I'm using .NET 8 with NSwag 14 and I'm getting the following issue after adding the package and use AddExampleProviders configuration method

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

Hi @AhmedHemdan21, I have fixed this in the prerelease branch and recently merged it into the master under version 1.0.12. Please try this version and validate the fix works for you. Thanks
