如何更改visual studio项目的目标？

Question

There is a visual studio solution, which is a host-container for react native. There are 7 projects in the solution

1. ChakraBridge (Universal Windows, C++)
2. Facebook.Yoga.Shared
3. ApplicationMobile (Universal Windows, C#)
4. ReactNative (Universal Windows, C#)
5. ReactNative.Shared
6. ReactNativeWebViewBridge (Universal Windows, C#)
7. yoga.uwp (Universal Windows, c++)

All the projects targeting 14393 version:

On compile I have lot of errors, that can be grouped in three types:

1. Predfined type "System.String" is not defined or imported

2. Your project does not reference "UAP,Version=v10.0.14393" framework. Add a reference to "UAP,Version=v10.0.14393" in the "TargetFrameworks" property of your project file and then re-run NuGet restore. for ApplicationMobile

3. Type universe cannot resolve assembly: System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. for react native

On my machine windows 1809-17663 is installed. I have tried to install the latest WDK, solution failed to build. I have changed the target version to 1809-17663 for all the projects in the solution, the application successfully built and run, however later discovered, that some features work only under 14393. I have installed SDK for 14393, from here https://developer.microsoft.com/en-us/windows/downloads/sdk-archive , but still has all the errors from above. Does somebody know how to build projects targeting 14393 when I am on windows 17663?

Answer 1

to sum up

1. Download 14393 SDK from https://developer.microsoft.com/en-us/windows/downloads/sdk-archive
2. Set build target and min version to 14393 for all projects
3. right-click on the solution -> retarget solution -> set target to 14393
4. Restart visual studio

Finally, I have accidentally seen an option in solution properties, retarget solution, on the screen it is disabled because project was running when making a screen.

1. Retarget solution to 14393
2. Restart visual studio
3. Unload/Load project ApplicationMobile (maybe optional:))
