Many thanks in advance,
As "angevoyageur" stated, they exist, but I doubt they are a good solution. They tend to be personal projects not backed by major support and lacking with regards to newer functionality of MetaTrader. They also usually require the use of external DLLs.
I wound recommend that you dedicate to developing your project with MQL4/5 instead, especially taking into consideration that MetaTrader 4 and 5 are merging and that any C# project you create with the API could soon become incompatible with future builds of MetaTrader.
