C# 无法加载文件或程序集'；BouncyCastle.Crypto，版本=1.8.1.0，区域性=neutral，PublicKeyToken=null'；或者它的一个依赖项

我正在尝试将沃尔玛.NETSDK集成到.NET4.61MVC5应用程序中。使用NuGet，我添加了对BouncyCastle.Crypto 1.8.1.0的引用

SDK使用.NET标准1.3，并引用BouncyCastle.Crypto 1.8.1.3：

1.8.1.3不适用于.NET 4.61

{"Could not load file or assembly 'BouncyCastle.Crypto, Version=1.8.1.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)":"BouncyCastle.Crypto, Version=1.8.1.0, Culture=neutral, PublicKeyToken=null"}

我不得不使用.NET46解决方案。Walmart.Sdk.Base程序集基于.NET标准1.3构建。我需要引用.NET 4.6中的库。

我的问题是在同一个解决方案中同时构建一个项目，该解决方案通过NuGet引用一个较旧的库，有时它会覆盖最新的库。升级此项目中的NuGet包修复了此问题。

dll不在您的bin文件夹中（调试或发布）。为了证明我是正确的，把弹跳球放入正确的垃圾箱文件夹中。如果可行，请执行以下操作：添加现有项，然后浏览BouncyCastle可执行文件。然后，编译器将在您构建时将最新的BouncyCastle复制到bin文件夹。您好，我没有看到BouncyCastle EXE，因为我使用的是.NET4.61。我没有使用.NETCore。.DLL存在于我的软件的调试文件夹中。这确实对我有帮助。谢谢。我很高兴这有帮助
