unit-testing - NUnit - System.IO.FileNotFoundException

Question

我试图将 .dll 加载到我以前从未使用过的 Nunit (NUnit) 中，当我尝试在 Nunit 中打开 .dll 时，出现以下错误。我不知道出了什么问题，谷歌对此并没有太多关注。有什么建议吗？

System.IO.FileNotFoundException...

确保 GloballyAssemblyCache 中没有开发阶段程序集。

在我的例子中，NUnit 无法加载 Npgsql.Tests.dll。

Npgsql.Tests.dll 链接到 Npgsql.dll。然而，GAC 有另一个具有相同版本的 Npgsql.dll 变体。

如果程序集具有完全限定的引用名称，如 Npgsql，Version=3.0.0.0，Culture=neutral，PublicKeyToken=5d8b90d52f46fda7，.NET 运行时首先尝试从 GAC 搜索程序集，然后搜索您的本地文件夹(程序集的探针)。我们可以在msdn上查看How the Runtime Locates Assemblies
