with the release of the .net core i have been trying to build a simple project, however whenever i try and add a dll reference in my project i get the following message
For referencing external dll in .net core you need to create you own nuget package.
The NuGet docs show how to create a package from a dll:https://docs.nuget.org/create/hosting-your-own-nuget-feeds . You can put that nuget package in a local folder and use that as a feed: [https://docs.nuget.org/create/hosting-your-own-nuget-feeds]
For this you need to edit the nuspec file and add the following code in the nuspec file.
<package>
*******--Some code--*****
<metadata>
<references>
<reference file="xxx.dll"/>
</references>
</metadata>
<--For addig reference of external dll-->
<files>
<file src="path\*.dll" target="lib\netCoreApp1.0"/>
</files>
Now create .nupkg file and install this package in your project.
Hope this solution works for you.
