Version Conflict errors in the Packages

Hi Friends,

I am facing problem with the Package updation in visual studio .net core Project.

Severity Code Description Project File Line Suppression State Suppression State

Error NU1107 Version conflict detected for Microsoft.Extensions.Configuration. Install/reference Microsoft.Extensions.Configuration 3.1.0 directly to project Services to resolve this issue.

Services -> Microsoft.Extensions.Hosting 3.1.0 -> Microsoft.Extensions.Configuration (>= 3.1.0)

Services -> Models -> Microsoft.AspNetCore.App 2.1.1 -> Microsoft.Extensions.Configuration (>= 2.1.1 && < 2.2.0)

I am getting this error in Services.proj and Project.csproj.I am using nuget.org(https://api.nuget.org/v3/index.json) in the package settings and I updated the packages but issues was not resolved.I tried with the following solutions

1)I added package references in the services.csproj and project.csproj.and agin I am getting the same error with different packages names So like that I added many package references with 3.1.0 version.Still I am not getting successful build.

2)I updated .net sdk 3.1.0 and I added microsoft offline packages and nuget.org both in the package settings.

I am not understanding how to fix package issues.

Please suggest me how to fix the issues.

Thanks in advance

If the package is not showing means it is not present so you need to reinstall it again. Thanks

Hi Salman,

I tried the same but the errors are increasing.In Nuget in Installed tab the package is not showing in the list.

Is there any alternative?

Hey first uninstall that package from nuget. While uninstalling please do check remove dependency checkbox. Then again install it from nuget. Thanks
