I am trying to migrate my WPF(.net framework) project to WPF(.net core 3). So i have installed this Visual Studio Extension and i m now able to create a new Wpf(.net core) project , but the problem starts when i add a nuget package ! , VS throws me this error :
Unable to find package Microsoft.NETCore.App with version (>= 3.0.0-preview6-27730-01)
- Found 69 version(s) in nuget.org [ Nearest version: 3.0.0-preview5-27626-15 ]
- Found 0 version(s) in Microsoft Visual Studio Offline Packages TestwpfCore C:\Users\sintware\source\repos\TestwpfCore\TestwpfCore\TestwpfCore.csproj 1
After getting @Lance is comment , i downloaded the Core 3 preview 6 and finally the problem is gone ,i can install nuget package without any problem.
