asp.net-core - .NET 核心构建输出包含大量 DLL 文件

Question

我有大约 30 个项目的 .NET Core 解决方案，但我没有得到一件事 - 每个项目编译的 Bin 输出都非常大。基本上它包含一大堆 Microsoft.AspNetcore.* 和 System.* 程序集，这使得输出大约为 15-30mb(即使对于非常小的项目)。
该解决方案分为较小的项目，目的是减少耦合，但现在它带来的麻烦多于帮助 - 所有编译项目的总体大小约为 700mb..

我同意“启动”/“复合根”项目是可以的，所有东西都应该放在一个地方，但现在看起来每个项目都是“发布”的，或者像编译为“独立”而不使用已安装的框架.

这本身不是问题，但它使解决方案在 CI/CD、发布工件等方面不那么健壮。有什么想法可能是错误的？真的像设计的那样吗？

一个可能的原因是由于某些历史原因，我的解决方案针对 net461(又名“完整”.NET Framework)。但是我正在考虑将所有内容移植到 netcoreapp1.x/netstandard。我试图用一些项目来做 - 它看起来像“库”项目它只复制几个程序集，但对于其他一些项目(例如用 xUnit 编写的测试) - 仍然有很多“基于框架的”DLL，可以从全局缓存或 smth 中使用。即使在 net461 当前情况仍然有点奇怪。

我还试图将所有构建的工件放在 CI 服务器上的一个文件夹中，但它还有其他问题 - 例如第三方库冲突，当在不同项目中使用不同版本库时。对于第三方库来说这是可以理解的，但是“框架”库可能会“更智能”。

好像是我自己找到的。。有CopyLocalLockFileAssemblies和 CopyNuGetImplementations .NET Core 项目的标志(即新式 *.csproj 文件)。

对于 .NET Core，它是:

<!-- dependencies coming from the package manager lock file should not be copied locally for .NET Core and .NETStandard projects -->
<CopyLocalLockFileAssemblies Condition="'$(CopyLocalLockFileAssemblies)' == ''">false</CopyLocalLockFileAssemblies>

对于 .NET Framework，由于某种原因，它被设置为“true”。因此二进制文件的大小如此之大。

关于 xUnit 项目 - 他们也覆盖这些标志并将它们设置为 true。实际上，当您使用 dotnet xunit 时，测试正在使它们“错误”。或 dotnet test ，但如果你想使用 xUnit console runner，它应该是真正的“真实” .

它并没有真正帮助我，但至少它解释了为什么会发生..
项目只有一个类，大约 5kb，但二进制输出为 16Mb，这真的很令人沮丧。
