.net-core Understanding System.Runtime vs. mscorlib Popular Error: Add a NuGet package which was not made for netstandard / netcoreapp (System.Runtime)
Example
In the example project.json below, an assembly Microsoft.AspNet.Identity.EntityFramework was added which is mscorlib based.
{
"version": "1.0.0-*",
"dependencies": {
"Microsoft.AspNet.Identity.EntityFramework": "2.2.1",
"NETStandard.Library": "1.6.0"
},
"frameworks": {
"netstandard1.6": { }
}
}
The author of the assembly Microsoft.AspNet.Identity.EntityFramework has not ported the NuGet package yet to netstandard (they actually did it, they just renamed the package as well Microsoft.AspNetCore.Identity.EntityFrameworkCore ;))
If you encounter a package you need and is not yet on netstandard, please contact the author and - if possible - help porting it.
