Nuget试图在某些软件包上安装大量依赖项

看来人们在nuget中的包装方式可能存在问题。

Yes, you are right. This issue is related to the author who packing the NuGet package. I have ever reported the similar issue on GitHub.

For the package MailChimp.Net.V3, there is a reported issue about installing wrong dependencies: Tons of new dependencies when updating to v3 on .net 4.6.2. This issue has been fixed at the version 3.1.1-alpha.

The package of Mandrill, this package has a dependency NETStandard.Library (>= 1.6.1), so it is correct to install tons of .NET shandard dependencies.

The package of MiniProfiler, which including a dependency of MiniProfiler.Shared (>= 4.0.0-alpha9-00206). This latest version of dependency package should be incorrect, it will install tons of .NET shandard dependencies. To resolve this issue, please install the previous version: MiniProfiler 4.0.0-alpha9-00202:

Hope this helps.
