Not sure where the one you're referring to is anymore, but what you're talking about is an Interactive Shell.

The only one I recall seeing is the <a href="http://www.mono-project.com/CsharpRepl" rel="nofollow noreferrer">CSharpRepl</a> which was released by the Mono team. CSharpRepl also contains the Compiler As a Service functionality that the Mono team developed.

You can use the <a href="http://msdn.microsoft.com/en-us/library/microsoft.csharp.csharpcodeprovider.aspx" rel="noreferrer"><code>CSharpCodeProvider</code> class</a> to compile assemblies at runtime.

You'll need to make a boilerplate template to wrap the macro commands in a static method in a class.

For example:

<pre><code>static readonly Assembly[] References = new[] { typeof(Enumerable).Assembly, typeof(Component).Assembly };
public Action CompileMacro(string source) {
 var options = new CompilerParameters(References.Select(a =&gt; a.Location).ToArray()) {
 GenerateInMemory = true
 };
 string fullSource = @"public static class MacroHolder { public static void Execute() { \r\n" + source + "\r\n} }";
 try {
 var compiler = new CSharpCodeProvider(new Dictionary&lt;string, string&gt; { { "CompilerVersion", "v4.0" } });

 var results = compiler.CompileAssemblyFromSource(options, fullSource);

 if (results.Errors.Count &gt; 0)
 throw new InvalidOperationException(String.Join(
 Environment.NewLine, 
 results.Errors.Cast&lt;CompilerError&gt;().Select(ce =&gt; ce.ErrorText)
 ));

 return (Action)Delegate.CreateDelegate(
 typeof(Action),
 results.CompiledAssembly.GetType("MacroHolder").GetMethod("Execute")
 );
 } finally { options.TempFiles.Delete(); }
}
</code></pre>

Maybe you mean <a href="http://codepadnet.codeplex.com/" rel="nofollow noreferrer">CodePad.NET</a>? Well, it's not a command-line app but it is open-source and might point you in the right direction.

You can try <a href="http://csscript.net/" rel="nofollow noreferrer">CS-Script</a> as an alternative - allows you to run individual C# files as if they were script files.

blocks|key|3662556|text|如果您愿意接受其他建议，您现在可以使用Python、F#或Boo作为宏语言。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3662557|我自己更喜欢Python；它是设计最好的语言之一。C#在后来的开发中大量借鉴了Python语言(迭代器块、lambda等)。|3662558|Manning+Publications有一本名为IronPython+in+Action的书；第15章介绍了如何在其他程序中使用IronPython+(作为脚本引擎或插件)。|offset|length|3662559|entityMap|0|LINK|mutability|MUTABLE|url|http://tinyurl.com/2da5fbs^0|0|0|P|K|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

If you're open to other suggestions, you can use Python or F# or Boo as a macro language today.

I prefer Python, myself; it's one of the best-designed languages. C# has borrowed heavily from Python in its later developments (iterator blocks, lambdas, ...).

Manning Publications has a book called <a href="http://tinyurl.com/2da5fbs" rel="nofollow noreferrer">IronPython in Action</a>; chapter 15 is all about using IronPython in other programs (as a scripting engine, or as plugins).

I wouldn't go Python, it doesn't have the .NET infrastructure, therefore you are limited.

F# is amazing.

The Compiler-as-a-Service feature has been <a href="http://Go-Mono.Com/docs/index.aspx?link=N:Mono.CSharp" rel="nofollow noreferrer">available in Mono</a> for quite some time and there are signs that it might appear in .NET 5 or 6, but it's not available in .NET 4.
If you absolutely, positively, need to run on .NET (note that Mono runs on Windows just fine, so you don't actually lose anything by running Mono), one interesting option might be to investigate how hard it would be to port <code>Mono.CSharp</code> to .NET. I mean, ultimately, at some point, it generates CIL bytecode which works exactly the same across all CLI implementations whether that be Mono, .NET, DotGNU, Rotor, Bartok or whatever.
Otherwise, your options are pretty much the same they have always been: generate files and call the commandline compier, use DLR trees, use lightweight code generation, use <code>Reflection.Emit</code>, use CodeDOM, use <code>CSharpCodeProvider</code>, create your own scripting language, host some other scripting language or host the DLR.
I'd probably go for the latter: hosting the DLR is absolutely easy and it gives you access to not only one but several good scripting languages (at the moment Ruby, Python, ECMAScript and Scheme) and in fact the user can use any DLR language they have installed on their machine.

I remember when .NET 4 was in beta there was a video of a developer that made a command-line app that he could type C# code into and it would compile the code on the fly. The idea was that the compiler was now available in the .NET language. 

Anyone recall where this is? I need to create an application with a small macro language and I would love to use C# as that macro language, but I don't know where to find this library..

我记得当.NET 4还处于测试阶段时，有一个视频是一位开发人员制作了一个命令行应用程序，他可以在其中输入C#代码，然后它会在运行时编译代码。这个想法是编译器现在可以在.NET语言中使用。有没有人记得这是哪里？我需要创建一个使用小型宏语言的应用程序，我希望使用C#作为宏语言，但我不知道在哪里可以找到这个库。
