The wwDotnet Bridge class shares the same features as the wwDotnetBridge class but works against .NET Core 3.0 or later components. Like the full framework version wwDotnetCoreBridge hosts a copy of .NET Core and provides a class factory and proxy implementation to create instances and access features that COM does not natively expose.

The only difference between wwDotnetBridge and wwDotnetCoreBridge is how they are instantiated and most other features are identical. Please refer to the wwDotnetBridge documentation for a member documentation.

Requires that .NET Core 3.0 or later is installed

This library requires that the .NET Core 3.0 runtime is installed on the machine. It searches for the highest version available on the machine and uses that to host the .NET Core runtime.

Instantiation

Behaviorly there are no major differences between wwDotnetBride and wwDotnetCoreBridge. Once loaded you can expect the same behavior and member interface between the two. P
