NuGet安装软件包错误

Question

i am currently trying to create a NuGet package for zLib ( http://www.zlib.net/ ). I used the "grpc zlib" NuGet package ( https://www.nuget.org/packages/grpc.dependencies.zlib/ ) to copy the folder structure and then added the zLib .dll, .lib and header files.

This is my self crafted zlib NuGet-package: https://drive.google.com/file/d/0B_2A8x02vzDwOWVGUmxkeGdBNm8/view?usp=sharing

However when i try to install my package in VS, then i get following error:

Severity Code Description Project File Line Suppression State Error Could not install package 'zlib 1.2.8'. You are trying to install this package into a project that targets 'native,Version=v0.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author. 0

Using the grpc zlib package is working fine.

Thanks for your help in advance!

Answer 1

You need add the .targets in to identify the assembly and winmd files in your package.

According to the error and your package, the .targets /or .props was missing in your \\build folder.

C++ and JavaScript projects that might consume your NuGet package need a .targets file to identify the necessary assembly and winmd files.

Please refer to the “Adding .targets” part in this link .

Detailed information for .targets, please focus on .targets content in the document: Deep Dive into NuGet Native , and pay attention that .targets must be named the same as the package ID with the .targets and/or .props extensions.

Answer 2

Well the point with my NuGet-package obviously was that there was the .targets file missing. I added the file using this and this (thanks to @Wendy - MSFT) for help. I also looked at .target files of some existing zlib-packages to figure out, how the file has to look like.
