Bug: Standalone server throws 500 error when receiving concurrent requests

[FSatmar]

Hi,
I'm trying to use the WireMock Net as a standalone service but when I run multiple tests in parallel which call the admin api to create or delete mappings, the server often fails with a 500 error code. Any chance to to have this fixed?

The stacktrace:
System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
at System.Collections.Generic.List1.Enumerator.MoveNextRare() at System.Collections.Generic.List1.Enumerator.MoveNext()
at System.Linq.Enumerable.FirstOrDefault[TSource](IEnumerable1 source, Func2 predicate)
at WireMock.Server.FluentMockServer.RegisterMapping(Mapping mapping)
at WireMock.Server.RespondWithAProvider.RespondWith(IResponseProvider provider)
at WireMock.Server.FluentMockServer.DeserializeAndAddMapping(String json, Nullable`1 guid)
at WireMock.Server.FluentMockServer.MappingsPost(RequestMessage requestMessage)
