I want to use Open flight(OF) API for C#, Any one from forum who already work on it ? Or give me suggestion how can i use C# for OF API??

Thanks

As you are probably aware, the OpenFlight API is an "unmanaged" library so cannot be used directly in a "managed" environment (either managed c++ or c#). There are ways to use unmanaged code in c# and many articles on the web describing the process.

Here is just one found using a web search on "using an unmanaged library in c#"

How much of the OFAPI you will need to expose in this way will depend on what "data" from the OFAPI you need in your c# environment,

That's great, thanks for your guidelines.I continue work on it. Thanks again.
