使用CLR 4.6.1库对asp.net Core项目进行单元测试

我正在构建一个运行在CLR 4.6.1上的asp.net Core项目。它使用遗留的CLR 4.6.1库，这是一个很大的问题。因为。net Core VS工具不能正确地构建项目，我不得不编写构建脚本来修复它-结果是VS无法构建项目的工作版本。

考虑到这一点，我如何对其进行单元测试?理想情况下，我想要一个可以加载预编译项目的独立测试运行器，以避免测试工具不得不构建我的主项目。

我已经尝试了MSTest(它无法看到对SUT的引用)和Xunit使用dotnet test(它试图构建项目)。

按要求，我的(稍微消毒过的)project.json:
