How to "import" a static class in C#?

There's no way of doing this in C# - no direct equivalent of Java's static import feature, for example.

For more information about why this is the case, see Eric Lippert's post on the topic and a similar SO question.

In certain circumstances, however, it may make sense to write extension methods which live in non-nested static classes but "pretend" to be instance methods of a different class. It's worth thinking carefully before you introduce these, as they can be confusing - but they can also improve readability when used judiciously.

What sort of utility methods were you thinking of?

What Jon Skeet is not telling you is that you can have global static members in c#. Your utility class can indeed become a reality in c#.

Unfortunately, Microsoft has determined that the very process of constructing such members as above mere "normal" development, and requires that you forge them from raw intermediate language. Such a powerful pattern is above common syntax highlighting and friendly icons).

Here is the requisite sequence of utf-8 characters (guard it carefully):

.assembly globalmethods {}

.method static public void MyUtilMethod() il managed 
{
  ldstr "Behold, a global method!"
  call void [mscorlib]System.Console::WriteLine(class System.String) 
  ret
}

(You could compile this example by invoking ilasm.exe from the SDK command prompt, remembering to use the /dll switch)

ilasm.exe output:

Once you have compiled your newly created assembly (as "globalmethods.dll" for example), it's just a matter of adding a reference in Visual Studio. When that is complete, you better be sitting down, because it will be time to write some real code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reflection;

namespace TestGlobalMethod
{
    class Program
    {
        static void Main(string[] args)
        {
