Trying to build integration test with connection to db in ServiceStack. My ServiceStack app is working fine, but when I run simple test I got this error message in line:22

System.MissingMethodException: 'Method not found: 'Int32 ServiceStack.DataAnnotations.CustomFieldAttribute.get_Order()'.'

There is a lite cod:

Anytime you see a missing type or missing method exceptions when using the MyGet pre-release packages it means you have a dirty installation (i.e. using pre-release packages from different build times).

In which case you'd need to Clear your Nuget packages cache and download the latest packages again, which ensures all your packages are from the latest same build:

$ dotnet nuget locals all -clear
