A ton of conflicts on simple UWP project

Question

I have a simple project where I'm getting thousands of errors in, most likely because some UWP/.NET Core dependency issue. The project.json file is very simple:

{
  "dependencies": {
    "Microsoft.NETCore.UniversalWindowsPlatform": "5.0.0",
    "Newtonsoft.Json": "8.0.3"
  },
  "frameworks": {
    "uap10.0": {}
  },
  "runtimes": {
    "win10-arm": {},
    "win10-arm-aot": {},
    "win10-x86": {},
    "win10-x86-aot": {},
    "win10-x64": {},
    "win10-x64-aot": {}
  }
}

These are all the errors I'm getting: http://pastebin.com/WwPKzCgK Example of errors:

Version conflict detected for System.Collections.
 WebServer (≥ 1.0.0) -> Microsoft.NETCore.UniversalWindowsPlatform (≥ 5.0.0) -> Microsoft.NETCore.Runtime (≥ 1.0.0) -> Microsoft.NETCore.Runtime.CoreCLR-arm (≥ 1.0.0) -> System.Collections (= 4.0.10)
 WebServer (≥ 1.0.0) -> Microsoft.NETCore.UniversalWindowsPlatform (≥ 5.0.0) -> Microsoft.NETCore (≥ 5.0.0) -> System.Collections (≥ 4.0.10).
Version conflict detected for System.Diagnostics.Debug.
 WebServer (≥ 1.0.0) -> Microsoft.NETCore.UniversalWindowsPlatform (≥ 5.0.0) -> Microsoft.NETCore.Runtime (≥ 1.0.0) -> Microsoft.NETCore.Runtime.CoreCLR-arm (≥ 1.0.0) -> System.Diagnostics.Debug (= 4.0.10)
 WebServer (≥ 1.0.0) -> Microsoft.NETCore.UniversalWindowsPlatform (≥ 5.0.0) -> Microsoft.NETCore (≥ 5.0.0) -> System.Diagnostics.Debug (≥ 4.0.10).

How can I resolve the conflicts?

Answer 1

I don't know why I'm only getting this on the Microsoft UWP samples downloaded from GitHub, but to resolve this, I do the following:

1. Open the Nuget Manager in my project.
2. Uninstall Microsoft.NETCore.UniversalWindowsPlatform
3. Search for Microsoft.NETCore.UniversalWindowsPlatform in Nuget, then re-install. Be patient on this par as while I have a decent internet connection, it still takes a bit of time to display the "install" dialog.
4. Install the Nuget package.

That usually sort out the problem.

Hope this helps.
