[C#] Method signatures use incorrect casing when generated since PR #6305

[jamesbar2]

Description

Since Issue #6281 and PR #6305, the parameters in model constructors are not using the recommended style rules from Microsoft. This creates breaking changes for our users who are using this formatting:

Old:

new Model(argument1: "foo", argument3: "bar")

New:

new Model(Argument1: "foo", Argument3: "bar")

This does not apply to the API method parameters, only model constructor parameters.

Swagger-codegen version

2.3.0

Swagger declaration file content or url

JSON Language Configuration File:

{
    "packageName": "MyApi.Client",
    "apiPackage": "Api"
}

Also, attempting adding "modelPropertyNaming": "camelCase", this provided the desired result for the parameters, but then the models were also named in camelCase.

Command line used for generation

docker run --rm -v /swagger_codegen:/local swaggerapi/swagger-codegen-cli generate -i /v1.json -l csharp -o /local/generated/csharp -c /local/csharp.json

Switch back to using camelCase on the model constructors, per the style guidelines from Microsoft.

@jamesbar2 Sorry I've just seen this issue. My mother passed in September, and I took a hiatus from open source contributions for a while.

I'll try and have a fix for this by tonight or tomorrow night. I agree that, regardless of property naming, constructor parameters should follow Microsoft's naming guidelines. The fix I have in mind will cause constructor parameters to always be generated in camelCase, so if you were to use PascalCase property names or snake_case… it should never affect named constructor args.

However, if your users are doing object initializers, any non-PascalCase change to property naming convention would be a client breaking change.

@jamesbar2 I've opened #7519 to fix this bug. I was wondering if you'd have a minute to evaluate the branch?

@jimschubert I'll check it out now! Sorry to hear about your mom, thanks so much for taking a look a this!
