防止将我的 NuGet 包安装到使用不受支持的目标框架的项目中

我的 NuGet 包面向 .NET Standard 2.0 和 .NET Framework 4.0。

.nuspec 如下所示：

<?xml version="1.0"?>
<package>
  <metadata>
    ...
    <dependencies>
      <group targetFramework=".NETStandard2.0"/>
      <group targetFramework=".NETFramework4.0"/>
    </dependencies>
  </metadata>
  <files>
    <file src="...\net40\WinSCPnet.dll" target="lib\net40"/>
    <file src="...\netstandard2.0\WinSCPnet.dll" target="lib\netstandard2.0"/>
  </files>
</package>

包中包含的程序集具有：

<TargetFrameworks>net40;netstandard2.0</TargetFrameworks>

但这并不妨碍将包安装到针对不同框架的项目。例如，它可以安装到面向 .NET Framework 3.5 的项目。显然它不起作用，因为没有 3.5 版本的程序集。

我认为应该可以以某种方式阻止将包安装到针对不受支持的框架的项目。例如，问题 NuGet 包未安装在 .NET Framework 中显示某些包由于这个原因无法安装。我如何在我的包中实现这一目标？

My NuGet Package targets .NET Standard 2.0 and .NET Framework 4.0.

The .nuspec looks like:

<?xml version="1.0"?>
<package>
  <metadata>
    ...
    <dependencies>
      <group targetFramework=".NETStandard2.0"/>
      <group targetFramework=".NETFramework4.0"/>
    </dependencies>
  </metadata>
  <files>
    <file src="...\net40\WinSCPnet.dll" target="lib\net40"/>
    <file src="...\netstandard2.0\WinSCPnet.dll" target="lib\netstandard2.0"/>
  </files>
</package>

The assembly included in the package has:

<TargetFrameworks>net40;netstandard2.0</TargetFrameworks>

But this does not prevent the package from being installed to projects that target different frameworks. For example it can be installed to project targeting .NET Framework 3.5. Obviously it does not work then, as there's no 3.5 version of the assembly.

I assume it should be somehow possible to prevent installing the package to projects targeting unsupported frameworks. For example question NuGet package not installing in .NET Framework shows that certain packaged failed to install for this very reason. How do I achieve that in my package?
