Dotnet restore not working

Question

• dotnet Version: 1.1.0 (global.json)
• NuGet Version : 4.4.1.4656
• VS2017 v15.5.2 (as Administrator)
• .NET Core 1.1
• The solution I am trying to build

Update I: I just changed the project to run under target framework .NET Core v2.0 & sdk version 2.1.3 and I only get these kind of errors:

Severity Code Description Project File Line Suppression State Error NU1202 Package Microsoft.Extensions.FileProviders.Physical 1.1.0 is not compatible with netcoreapp2.0 (.NETCoreApp,Version=v2.0). Package Microsoft.Extensions.FileProviders.Physical 1.1.0 does not support any target frameworks. AspNetCoreExample C:\Users\Admin\Source\Repos\Examples\src\AspNetCoreExample\AspNetCoreExample.csproj 1

Update II:

While the following solves the current issue, i am not sure if it solves the root cause for this issue.

Delete the global nuget.config file %AppData%/Nuget/Nuget.config.

I fixed this issue by doing the following: I migrated the project to .net core 2.0 and changed the global.json to point to sdk 2.1.3. Removed all references in AspNetCoreExample manually and added the latest version for all of them.

.NET Core SDKs installed:

.NET Host

Now when opening the solution I get:

Answer 1

Comparing the log entries you pasted to their AppVeyor build,

https://ci.appveyor.com/project/Autofac/examples

Your machine's NuGet configuration seems to be broken. Analyze that and fix the issues.

Answer 2

You should add this code to your .csproj file

<RuntimeFramework>2.0.3</RuntimeFramework>

This worked for me.
