C# - REST Error?
Downloaded a Sample App. I am using VS2015. The app doesn't compile. I am receiving what seems to be a REST error.
CS1503 Argument 2: cannot convert from 'System.Action<System.IO.S tream>' to 'byte[]' Tradovate.Services
The error is occurring at
request.AddFile(param.Valu e.Name.ToS tring(), param.Value.Writer,
param.Value.FileName.ToStr ing(), param.Value.ContentType.To String());
In the below code.
Any ideas?
