Does anyone knows if there is a technical limitation and therefore
this feature is simply not feasible for .NET Core?
I’m afraid the answer is negative.
So far this option only supports for .net framework, and not for .net core project and .net standard project temporarily.
To get this option available for .net core projects in VS it needs support from both Project-system and Roslyn. For now the Project’system work is done, you can track this issue to follow the progress of the rest work in Roslyn.
Anyone having a good workaround to still initialize the project (with
the complete context) manually?
Go View=>Other Windows=>C# Interactive to get the window,and use #r command(#r "Path/MyDll.dll") to load the assembly manually.For complete context,you also need to manually load all the referenced assemblies.
Actually not a good workaround, it seems there has a way to go before the product team complete the feature, sorry for the inconvenience 🙁
