Code Generation of Enum attributes in aspnetcore server omits quotes.

Description

Code Generation of Enum attributes in aspnetcore server omits quotes.

Swagger-codegen version

2.3.1

Swagger declaration file content or url

https://gist.github.com/dpmartin990/d38d14b160998ce0ad780d6b3df3e1b1

Command line used for generation

java -jar swagger-codegen-cli.jar generate -i "C:\Users\dmartin3\Documents\PE\GitHub\Sandbox\MyCode\MyCode\swagger.forservergeneration.json" -l aspnetcore -o "C:\Users\dmartin3\Documents\PE\GitHub\Sandbox\XXXCompany.API.Admin" -D"packageName"="XXXCompany.API.Admin"

(Note I replaced my real company name with this fake one.)

Steps to reproduce

Files were generated as expected, when I opened the solution in VS 2007 latest updates I had to

1. Remove the project and then re-add it, I see others have used this workaround since the project will not load

2. Do a search and replace looking for Enum attributes like the below and change them to have quotes, i.e.

        [EnumMember(Value = TypeMismatch)]
        TypeMismatchEnum = 6
   

to this:
[EnumMember(Value = "TypeMismatch")]
TypeMismatchEnum = 6

Suggest a fix/enhancement

I think it should be a simple matter of adding quotes in the code. Not sure quite what's wrong with the project file.

Start by reproducing the aspnetcore server generation with the linked Swagger declaration and the documented swagger-codegen command, then inspect the templates responsible for generated enum attributes. Done means generated EnumMember Value attributes contain quoted enum names and the generated project loads without the reported workaround.
