Compiler Error CS0811

  • Article

The fully qualified name for 'name' is too long for debug information. Compile without '/debug' option.

There are size constraints on variable and type names in debug information.

To correct this error

  • If modifying the name is not possible, the only alternative is to compile without the /debug option.

Example

The following code generates CS0811:

// cs0811.cs
//Compile with: /debug
using System;
using System.Collections.Generic;

namespace TestNamespace
{
    using Long = List<List<List<List<List<List<List<List<List<List<List<List<List
   <List<List<List<List<List<List<List<List<List<List<List<List<List<List<List<int>>>>>>>>>>>>>>>>>>>>>>>>>>>>; // CS0811

    class Test
    {
        static int Main()
        {
            return 1;
        }
    }
}
