 The C# solutions are executed with the help of [wrapper code](https://github.com/ReCodEx/utils/blob/master/runners/cs/Wrapper.cs). This code searches for `main` method in submitted source codes. There has to be only one class containing `main` method, otherwise error will be thrown. The name of the file containing wrapper code is `ReCodEx_Csharp_Wrapper.cs` and it contains namespace `CodEx` with class `Wrapper`, so be aware of filename and class collisions.

Therefore for every C# build in ReCodEx there is [Reader.cs](https://github.com/ReCodEx/utils/blob/master/runners/cs/Reader.cs) library included to make life of C# programmers easier. Please note that library is suppose to work only with ASCII files and some difficulties can be observed with modern Unicode (UTF-8) encodings.
