[C#] fix the location of FodyWeavers.xml

[wing328]

PR checklist

• Read the contribution guildelines.
• Ran the shell/batch script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run./bin/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates)
• Filed the PR against the correct branch: master for non-breaking changes and 2.3.0 branch for breaking (non-backward compatible) changes.

Description of the PR

• fix the location of FodyWeavers.xml
• minor template change for better code format

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \

@wing328 how are you building this? The XML is supposed to be in the project root, so I'm not sure what's being fixed here.

I did another test to confirm it's working for me (Mac, Xamarin 5.x).

The PR aims to address this particular issue: #3547 (comment)

Does it work for you if you use the latest master to generate C# API client with generatePropertyChanged switched on?

@wing328 thanks. I'll check this when I get a chance. My new baby was born on September 2, so it's been hectic at home.

Did you update Project.mustache? I'm on mobile which sometimes doesn't show all affected files.

Congratulations to your new born 👏 👏 👏

I didn't update project.mustachte, which is referring to the xml file in the project root directory (not the solution root directory).

I'll ask others to give it a try as well so don't worry about it.

(I'll also setup CI for this)

Updated CI with #3796 to cover C# API client with "PropertyChanged"
