One or more packages are incompatible with .NETStandard,Version=v1.5
Tl;dr - it has to be netstandard
all the way down!
To install a package in a .NET Core project, the package and all of its dependencies must be compatible with netstandard1.X
.
It looks like your project targets netstandard1.5
, but depends on a package that only targets net45
. The only way to resolve this is to replace the dependency, or update it to a version that targets netstandard
.
In some cases, imports
will allow you to use a Portable Class Library in a .NET Core application. This isn't a general cure-all for incompatible packages, but rather a temporary fix that works with packages that already target a smaller API.

I created a new .NET Core Class Library and added a Nuget package from an internal company Nuget server. I began getting the following error:
Package XXXX is not compatible with netstandard1.5 (.NETStandard,Version=v1.5). Package XXXX 1.0 supports: net45 (.NETFramework,Version=v4.5) One or more packages are incompatible with .NETStandard,Version=v1.5.
I updated the project.json file to look like this but the same error persists.
{ "version": "1.0.0-*", "dependencies": { "XXXXX": "1.0.0", "NETStandard.Library": "1.5.0-rc2-24027" }, "frameworks": { "netstandard1.5": { "imports": [ "dnxcore50", "portable-net45+win8" ] } } }
Does anyone have insight on this?

Tyson Nero almost 8 yearsI've seen a couple references that say including "portable-net4+win8" with net4 being the framework version will fix this issue. E.g. docs.efproject.net/en/latest/miscellaneous/….

Nate Barbettini almost 8 years@GrandMasterT Does importing
portable-net45+netcore45+wp8
work for you? -
svick almost 8 years@GrandMasterT That can work only if the package is a Portable Class Library. It doesn't seem your package is that.

Tyson Nero almost 8 years@NateBarbettini No, importing is not working in my case. I know that it does work with several other Nuget packages or libraries. EF and xUnit are just two examples.
