Isn't this nuget artifact incompatible with .net 3.5? I haven't pulled this to try, as I've been busy. .NET 3.5 isn't documented on the Nuget page.

Also, this nuget assembly has to be added to compile.mustache.

@jimschubert The nuget is not compatible with .net 3.5.

Is .net 3.5 supported by swagger-codegen? (I don't see where)

[jimschubert]

Yes. Please run the CLI with config-help -l csharp.

The default conditions in our templates are .NET 3.5 compatible. Options are passed to templates for additional features such as async support. We also pass additional properties such as net40 as helpers to indicate special cases. You can generate with debug flags enabled to see these template parameters.

@jimschubert the nuget artifact is compatible with .NET 3.5 but on release v1.2.0 (see: https://www.nuget.org/packages/JsonSubTypes/1.2.0#show-dependency-groups)

I'll make another PR in order to handle .NET 3.5

[jimschubert]

Cool. I didn't see that when I looked.

Are there API differences in usage between these versions? If not, it should just be a simple template switch in the project files, build script, and package file.

@jimschubert There is no API differences in usage
