问题
I have a Xamarin forms mobile project (Android and iOS).
When I try to install the AWSSDK.S3 to access Amazon services, I get the following linker error when trying to build iOS:
Failed to resolve "System.Void Amazon.Runtime.Internal.Util.AESEncryptionPutObjectStream::.ctor(System.IO.Stream,System.Byte[],System.Byte[])" reference from "AWSSDK.Core, Version=3.3.0.0, Culture=neutral, PublicKeyToken=885c28607f98e604"
..Android build has a similar error.
I have the following libraries installed:
AWSSDK.S3 v3.1.1.1 AWSSDK.Core v3.3.4 AWSSDK.SecurityToken v3.3.0.2 AWSSDK.CognitolIdenity v3.3.0.2 AWSSDK.CognitoIdentityProvider v3.3.1.2 PCLCrypto v2.0.147 PCLStorage v1.0.2
the only code in my project is:
var amazonClient = new AmazonS3Client();
Any ideas?
回答1:
possible (bad) workaround that seems to work:
change in Linker Options/Linker behavior:
to: Don't link
instead of: Link SDK Assemblies only

The answer turns out to be found here:
Xamarin Forms IOS Failed to load assembly System.Net.Http.Primitive
even though its a different assembly error, the fix is the same:
- update all the AWS.Core to the latest version: v3.3.6 in my case
- install Microsoft.Bcl.Build v1.0.21
- install Microsoft.Net.Http v2.2.29

Rolling back to AWSSDK.S3 V3.1.10 worked for me, done using the NuGet manager in Visual Studio. =)
