Compiler Error CS0401 

Error Message

The new() constraint must be the last constraint specified

When using multiple constraints, list all other constraints before the new() constraint.


The following sample generates CS0401.

// CS0401.cs
// compile with: /target:library
using System;
 class C<T> where T : new(), IDisposable {}  // CS0401

class D<T> where T : IDisposable
   static void F<U>() where U : new(), IDisposable{}   // CS0401
