This bugs regards newest csharp feature described here:
http://tirania.org/blog/archive/2011/Feb-24.html

In short it's not possible to declare with property. Here is my repl log:

csharp> public class C { public int Speed{get;set;}};
csharp> C c = new C();
Mono.CSharp.InternalErrorException: builder already exists
  at Mono.CSharp.Parameter.ApplyAttributes

Reproducible: Always

Steps to Reproduce:
1.open csharp repl
2.declare class as: public class C { public int Speed{get;set;}};
3.declare C instance: C c = new C();
Actual Results:  
exception is thrown:

Mono.CSharp.InternalErrorException: builder already exists

unknown>:0 


Expected Results:  
C class declaration 

i've tried:
public class D { int x; public int X { get { return x; } set { x = value;} } };
public class C { public int Speed{get;set;}};
both results in the same error. Additional thing is that it's not possible to
leave csharp repl with "exit" command after this error (should i fill another
bug)
