如何从针对完整 .NET 框架的 .NET SDK csproj 中删除默认/锁定程序集引用？

Question

I have a new csproj format project that is using <TargetFramework.net472</TargetFramework> (targeting full .NET Framework), which adds default set of immutable assembly references to the project (as shown on the screenshot).

For example, System.Drawing is locked and can not be removed.

Yes, I know, if I don't use any classes from System.Drawing , it will not be actually referenced.

But still, is there any way to remove/ignore/hide it?

I've already tried alias trick to hide it:

<Reference Update="System.Drawing">
  <Aliases>excluded</Aliases>
  <Private>false</Private>
</Reference>

Did not work.

I have nothing against System.Drawing per se — but, what if I have another assembly which exports types with exact same namespaces and names — how to "shadow" existing reference?

Update: csproj looks like this:

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net472</TargetFramework>
    </PropertyGroup>
</Project>

Answer 1

By default System.Drawing is not referenced in new .net 4.7.2 project.

And if u reference it, u can remove reference when u want it

Answer 2

Just in case anybody is still searching for an answer: set the DisableImplicitFrameworkReferences property to true, then add references to the assemblies that are actually needed.
