[C#] modelPropertyNaming not honored in v2.4.1 SNAPSHOT

Description

It seems that between versions 2.3.1 and 2.4.1, modelPropertyNaming stopped working. We haven't changed a thing - in fact, I tried this with the very same definition file from a few months back that was fine with 2.3.1 - and all of the method parameters are now coming back as camelCase instead of the setting we use of PascalCase.

This is the second problem we've had with the CodeGen API using 2.4.1 today, the other being that any classes named "Void" are no longer being renamed (eg "ModelVoid") to avoid conflicts.

Please consider not using a SNAPSHOT as a code base for the API and online generator. Or, better, allow access via the URL to earlier, stable versions.

Swagger-codegen version

Using the online version. Last time we used our code creation utility, v2.3.1 was in use. Today it was v2.4.1 SNAPSHOT.

Swagger declaration file content or url

This isn't really relevant as the issue is evident using the exact same definition file with the only difference being the version of CodeGen in use

Command line used for generation

Steps to reproduce

Also not relevant; we submit a URL of the definition file via the API:

http://generator.swagger.io/api/gen/clients/csharp

with the following arguments:

packageName = {OurAppName}
targetFramework = "v4.5"
modelPropertyNaming = "PascalCase"
nonPublicApi = False
sortParamsByRequiredFlag = True
useCollection = False
validatable = False
optionalAssemblyInfo = False
optionalProjectFile = False
optionalEmitDefaultValues = False`

Suggest a fix/enhancement

1. Fix or revert the changed code to honor the previous setting modelPropertyNaming directive.
2. Please only use stable, release generator code versions with the online and API generators.
3. Please consider providing an option to target a specific generator code version.

Start with the C# generator exposed at http://generator.swagger.io/api/gen/clients/csharp and compare handling of modelPropertyNaming between 2.3.1 and 2.4.1-SNAPSHOT. Verify that the same definition and PascalCase setting produce PascalCase model properties, and assess the request for stable or selectable generator versions.
