Home: Microsoft.Extensions.logging does not install on ASp MVC 5, .Net 4.6

[HoomanBahreini]

I am trying to install Microsoft.Extensions.logging Nuget on my ASP.Net MVC, .net 4.6, project and it fails...

I have seen a quite a bit of discussion on git about this issue, but could not find any solution... or workaround. Is Microsoft.Extensions.Logging compatible with .net 4.5? Or is this a bug?

Appreciate a work around...

This is what I get what I install: Microsoft.Extensions.DependencyInjection.Abstractions... Microsoft.Extensions.DependencyInjection.Abstractions has a dependency on this package.

Microsoft.Extensions.DependencyInjection.Abstractions contains only lib/netstandard2.0/, this is compatible with net461 however you will need at least version 4.3.0 of nuget to get support for netstandard2.0.

Hi, Thanks a lot... so I need to update my nuget, in order to be able to install Microsoft.Extensions.Logging?

So, Microsoft.Extensions.DependencyInjection.Abstractions is the dependant package which is causing problem....

So looks like VS Studio 2015 comes with an older version of Nuget... so if I upgrade to VS 2017 which comes with Nuget 4.x, then I should be able to install it?

For VS 2015 use 3.6.0 https://dist.nuget.org/visualstudio-2015-vsix/v3.6.0/NuGet.Tools.vsix

Thanks a lot @emgarten

So I upgraded to visual Studio 2017... at first it failed... Then I realized that if I am using .Net Framework, It has to be .Net 4.6.1 and above... after changing my .Net Framework, finally I could install it.

I had the same problem with .NET 4.7.2 and 4.6.1 and VS2015. They were complaining when I tried to install Sentry 1.0.1-beta and it looks like installing 3.6.0 nuget worked perfectly. It also required me to install dotnet-standard-support-vs2015-2.0.0-win-x86 for anyone looking. Thank you!
