Could not load file or assembly 'BouncyCastle.Crypto, Version=1.8.1.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies

I am trying to integrate the Walmart .NET SDK into a .NET 4.61 MVC 5 app. Using NuGet, I added a reference to BouncyCastle.Crypto 1.8.1.0.

The SDK uses .NET Standard 1.3 and it references BouncyCastle.Crypto 1.8.1.3:

https://github.com/walmartlabs/partnerapi_sdk_dotnet

1.8.1.3 is not available for .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"}

My issue was a project building concurrently in the same solution which was referencing an older library through NuGet and occasionally it was overwriting the most recent one. Upgrading the NuGet package in this project fixed the issue.

I had to use the .NET 46 solution. The Walmart.Sdk.Base assembly is built on .NET Standard 1.3. I needed to reference the one for .NET 4.6.
