C# Edit and Continue: error 4053
Error Message
Modifying a '[method | property | indexer | operator | event | constructor | destructor]' which contains an anonymous method will prevent the debug session from continuing while Edit and Continue is enabled
You tried to modify a method, property, indexer, operator, event, constructor or destructor containing an anonymous method. Edit and Continue does not support this change during debugging.
Consider this code:
class Program
{
delegate void D();
static void Main(string[] args)
{
D d = delegate { System.Console.WriteLine("D"); };
System.Console.WriteLine("Main");
}
}
If you step into Main, then change WriteLine(“Main”) to WriteLine(“Hello”), this error occurs.
To correct this error
