How to redirect Assemblies Versions in u-sql projects?

Question

In my u-sql script I'm using the JsonExtractor that have a reference to "Newtonsoft.Json", in this script I also use a Custom Processor that uses "Newtonsoft.Json" too.

The problem is that the version used in the Processor is different from the version used by the JsonExtractor and it fails when load de dependencies of "Microsoft.Analytics.Samples.Formats.Json.JsonExtractor".

Is there a way to redirect assemblies?

Have you tried uploading each version of the assembly under a different name? — Neil P, Mar 29 '18 at 13:40

Each U-SQL database can only contain one version of any given assembly. For example, if you need both version 7 and version 8 of the NewtonSoft Json.Net library, you need to register them in two different databases. Furthermore, each script can only refer to one version of a given assembly DLL. In this respect, U-SQL follows the C# assembly management and versioning semantics.

In your custom processor just declare an alias for your version, and then you can use multiple dependencies by version. Is it possible to reference different version of the same assembly into a single project?
