CSharp client generation is wrongfully escaping characters from openapi file #6472
Description
What are you generating using Kiota, clients or plugins?
API Client/SDK
In what context or format are you using Kiota?
Nuget tool
Client library/SDK language
Csharp
Describe the bug
I am trying to generate a CSharp client out of a openapi.json. The json contains a schema with a property containing escaped characters.
It seems like the generated client escapes the characters on generation which can cause compilation errors.
link to repo: https://github.com/mchanyeechoy/kiota-generation-bug
Rather than generating:
public FilesInfoInput()
{
AdditionalData = new Dictionary<string, object>();
Content = "this is a test file with\nlinebreaks\nand \"strings surrounded by double quotes\"";
}it generated (which does not compile):
public FilesInfoInput()
{
AdditionalData = new Dictionary<string, object>();
Content = "this is a test file with
linebreaks
and "strings surrounded by double quotes"";
}Expected behavior
The property string should stay how it is from the json file. From the provided example, the \n and \" should not be converted to linebreaks and ". I would have expected the string: "this is a test file with\nlinebreaks\nand \"strings surrounded by double quotes\""
There should not be a requirement of escaping an already escaped character such as \\n.
How to reproduce
The repo contains the bug https://github.com/mchanyeechoy/kiota-generation-bug
I ran the command kiota generate -l CSharp -d ./openapi.json --exclude-backward-compatible --clean-output
The CSharp generated should be invalid

No response
Known Workarounds
using a script to escape the backslash characters so they won't get escaped on generation
e.g. replace \n to \\n

Hint: use the info command to get the list of dependencies you need to add to your project.
Example: kiota info -d "D:\git\kiota-generation-bug.\openapi.json" -l CSharp
Hint: use the --include-path and --exclude-path options with glob patterns to filter the paths generated.
Example: kiota generate --include-path "**/foo" -d "D:\git\kiota-generation-bug.\openapi.json"
