I'm trying to generate an NSwag C# Client, from an OpenAPI json file.

When I do this, I do get a client file generated, but it doesn't compile. It has created 2x partial classes in the same .cs file.

Now, if I change one of these class names to anything else, the file can now compile:

No errors - compiles OK.

So my question is: why is this doing it?

Here's a picture of my Swagger UI (this was generated with Swashbuckle, not NSwag):

So this means I have 2x controllers in the project:

• HomeController
• DocumentsController

Is there some trick to fixing this?

I used the following command line, to generate the client:

dotnet-openapi --updateProject .\MyProject.csproj http://localhost:5100/swagger/v1/swagger.json

Dotnet-openapi is using NSwag CSharpClientGenerator "under the hood", as far as I believe.

I'm happy to use any other tool to generate a C# client.
