Using .NET 3.5 Features with RunUO

[Ánheledir]

First, before I show you the tricky part there are some questions you should ask yourself:

• Are you willing to recompile the core? (Remember: You will not get support in case you have some script-problems and using a modified core even though your problem has nothing to do with it!)
• Are you sure you have installed the Microsoft .NET Framework 3.5 both on your Development-Server and your Productive-Server?
• Do you know what LINQ is or do you really need other (new) features of C# or VB.NET 3.0?
• Do you know what a Dictionary-Object is and what it is used for?
• Are you a geek?

In case you have answered one or more times with "no", leave this thread. Now. Also I do not recommend to do any core-changes you don't understand! I'm neither a teacher nor a debugger: If you have some strange problems with the following changes -> revert them or try to understand what the .NET-Compiler tries to tell you....


Sooo.... you are still with me? Excitingly reading how to use those cool new features like LINQ, anonymous classes, extensions, add-ins, ....?? Here is all the magic:

First: Open ScriptCompiler.cs and search for this line:

using ( CSharpCodeProvider provider = new CSharpCodeProvider() )

Second: Replace this line with the following:

var providerOptions = new Dictionary<string, string>();
providerOptions.Add( "CompilerVersion", "v3.5" );
using ( CSharpCodeProvider provider = new CSharpCodeProvider( providerOptions ) )

Repeat those steps for the VBCodeProvider(), too.

Yep, thats all... have fun

I run a a server RunUO 2.0 RC2 and my computer has 3.5 net and it still runs the server with no core modification. So 3.5 net does work with RunUO 2.0 RC2.

He means using new .NET 3.5-specific features.

OK, you have no clue what this patch is doing, do you?

You can obviously run RunUO 2.0 on .NET 3.5 'cause 3.5 doesn't have a new CRL. The .NET Core (CRL) is still on version 2.0. Then .NET 3.0 had a new version of C# and some new namespaces for WPF, WCF and WF, but it's only build around the 2.0 CRL. And now there is .NET 3.5 - and the biggest new feature is LINQ. But: It is using the 2.0 CRL, too.

So... in case you have installed .NET 3.0 or 3.5 you must have .NET 2.0 also. Because of that there is no problem running RunUO with the new Framework. But in case you want to use some of the new features from .NET 3.0 or 3.5, you must tell the internal script-Compiler from RunUO to compile against those new namespaces. And thats exactly what my little patch is doing.

Example 1:
Without this patch and only .NET 2.0 you have to write the following:

private bool _someProperty;
public bool SomeProperty {
get { return _someProperty; }
set { _someProperty = value; }
}

With this patch and .NET 3.5 you can shorten this to:

public bool SomeProperty { get; set; }

Example 2:
Without this patch and only .NET 2.0 you have to write the following:

Cloak c = new Cloak();
c.IsArcane = true;
c.MaxArcaneCharges = 10;
c.CurArcaneCharges = 10;

With this patch and .NET 3.5 you can simply write:

var c = new Cloak(IsArcane = true, MaxArcaneCharges = 10, CurArcaneCharges = 10);

These are only two small features of the new Framework you cannot use without this patch (RunUO would throw a exception on compile) and there are many more - but this is no place to advertise the new framework or to give lessons in LINQ

Ah i see i misunderstood you hehe .

Where In Hades is the "ScriptCompiler.cs " ?
I do a Search but it dont show anything exxcept Not Found.

You must not have the full RunUO 2.0 with server sources or you're looking in the Scripts directory. ScriptCompiler.cs is in the Server directory where the RunUO source is.
