Package .NET 框架 DLL 并在 .NET 标准项目中使用

Question

I have a vendor provided DLL which is based on .NET Framework. I do not have access to code and I only have the DLL. I have packaged this DLL into a nuget package and now I am trying to refer this into a .NET standard project. But I am getting warning as - Package 'MyPackage 0.0.1' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETStandard,Version=v2.0'. This package may not be fully compatible with your project. .

If I refer the DLL directly into a .NET standard project it doesn't show this warning. But using it after creating a nuget package shows that.

I also tried creating a .NET standard lib project, added DLL reference and then created a nuget package but still it was showing same warning.

Is there another way of doing it? Vendor doesn't provide DLLs targeting other frameworks and I have to use it after packaging it into Nuget because of requirements.

In my side, I test the situation as you described. Create a net standard lib project called test , then use this node to include into the package.

1) create a net standard lib nuget project called test and only add this node under test.csproj file:

<ItemGroup>
        <None Include="xxx\xxx\xxx.dll"(the whole path of the net framework dll) Pack="true" PackagePath="lib\$(TargetFramework)"></None>
</ItemGroup>

2) right-click on the net standard test project-->click Pack button and you can get the new version of the nuget package.

Before you install the nuget package into another main project, you should first clean nuget caches or delete all files under C:\Users\xxx(current user)\.nuget\packages .

And I did not face the issue in my side with all the above steps.
