Q: How does .NET Core compatibility assessment work?
Porting Assistant for .NET analyzes source code and both public and private NuGet package dependencies of your .NET application. It identifies incompatible API calls being made from each NuGet packages and checks whether NuGet package is compatible or incompatible to .NET Core. Based on the compatibility information of NuGet packages and .NET APIs, Porting Assistant for .NET designates a compatibility score which is an estimation of how much effort the application might require to port to .NET Core. The compatibility score is simply a ratio of compatible and incompatible APIs and can be used to identify and prioritize applications for your porting effort. Note that the compatibility score is just an estimation based on the compatibility information. The actual porting effort may vary.
