在Visual Studio解决方案中安装libwebp软件包失败

Question

Ok so I'm trying to implement webp support in to a solution of nopcommerce source code.

This is it on nuget :

I have looked through the google docs about it here but could not find anything explaining why the install fail.

In package manager console this is the output, but I'm not sure exactly how to fix it.

Answer 1

Could not install package 'libwebp.v140.redist 0.5.0.1'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.1', but the package does not contain any assembly references or content files that are compatible with that framework.

That why you can't install the package.
