AWS .NET SDK in Unity
Recently used the AWS .NET SDK in Unity and found that the documentation was a bit confusing. Leaving this here in case it can help anyone:

Put the DLLs in your assets folder. I put them under a plugins sub-folder.
I had to delete all .csproj and .sln files so they could be regenerated.
