13.2.0.0 generating non-working C# client with ChangeType as a culprit

Upgrading from 13.1.6.0 to 13.2.0.0 creates client, that compiles, but does not work (Can’t convert from System.String).

Problem is when client is generated, it tries to serialize json to types with ChangeType:

var responseData_ = response_.Content == null ? null : await response_.Content.ReadAsStringAsync().ConfigureAwait(false);
var result_ = (System.Collections.Generic.ICollection<string>)System.Convert.ChangeType(responseData_, typeof(System.Collections.Generic.ICollection<string>));

Old version does this correctly:

var objectResponse_ = await ReadObjectResponseAsync<System.Collections.Generic.ICollection<string>>(response_, headers_).ConfigureAwait(false);
return objectResponse_.Object;

Here is the bug repro for this issue: https://github.com/Enegia/NSwagGeneratorChangeTypeBugRepro

@scberr thanks, that fixed problem for us too.

We have tons of controllers, so we end up using global filter (startup.cs):

services.AddControllers(options =>
{
	options.Filters.Add(new ProducesAttribute("application/json"));
});

Have the same issue here. Just upgrades and the latest upgrade causes this problem
