| Can Reflector be made to disassemble delegates to Lambdas? |

For a simple example like
| Code: |
Func<int, int> xx =
delegate(int x)
{
return x*3;
};
|
if the View/Options/Disassembler/Optimization is set to .NET 2.0, you see the code as a delegate, but if you set it to .NET 3
.5 you see it as a lambda
| Code: |
Func<int, int> xx = x => x * 3;
|

You're found a bug, which affects assemblies compiled against the .NET 4 platform.
The code that decompiles a delegate as a lambda expression, has a guard which checks that the assembly containing the type references System.Query or System.Core.
Hence the following decompiles to a lambda expression
| Code: |
static void Main(string[] args)
{
Type foo = typeof (System.Linq.Enumerable);
Func<int, int> xx =
delegate(int x)
{
return x * 3;
};
}
|
but commenting out the typeof line causes Reflector to always decompile to a delegate (as the assembly no longers references out of the assemblies mentioned above).
I've logged this as RP-760. |

| This has now been fixed. The fix will be in the next EAP release. |
