Azure BlobClient.UploadAsync: "System.Security.Cryptogaphy.Algorithms is not supported on this platform" RRS feed

  • Question

  • I am using the .NET 5.0 framework.  When I use the BlobClient.UploadAsync command, I get an error saying: "System.Security.Cryptogaphy.Algorithms is not supported on this platform"

    This may be related to the fact that HMAC encryption is not supported (https://github.com/Azure/azure-cosmos-dotnet-v3/issues/1865)

    If that's the case, why is this built-in Azure library trying to implement this encryption algorithm, and how can I upload BLOBs without this happening using the SDK?
