Okta SDK - System.Runtime.InteropServices.RuntimeInformation Exception

I am using the Okta.Sdk nuget package (v4.0) in an ASP.Net Framework (4.6.1) application to create/update users.

All works well in the local Visual Studio environment, but when deployed to an IIS server we receive the following exception:

[FileLoadException: Could not load file or assembly ‘System.Runtime.InteropServices.RuntimeInformation, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)]
Okta.Sdk.Internal.HomePath.TryGetHomePath(String& homePath) +0
Okta.Sdk.Internal.HomePath.Resolve(String pathSegments) +95
Okta.Sdk.OktaClient.GetConfigurationOrDefault(OktaClientConfiguration apiClientConfiguration) +134
Okta.Sdk.OktaClient…ctor(OktaClientConfiguration apiClientConfiguration, ILogger logger, ISerializer serializer) +31

Have tried:

  • Explicitly adding the System.Runtime.InteropServices.RuntimeInformation nuget package
  • Adding a dependent assembly binding to the project for 0* to current version

It appears to be looking for a yaml file in the user’s home directory, despite our passing in configuration to the constructor.

Thanks in advance for any assistance,

It sounds like it should work according to the documentation

How are you passing the configuration exactly?
