Object Initializer Intellisense Broken

[KevinRansom]

originally opened at CodePlex by tahir_cs

Hi All,

I was trying to use the F# object initialization syntax in a FSharp script file (*.fsx) like so:

 let fileTarget = new NLog.Targets.FileTarget( Name = "logger" ) 

but no suggestions come through. A workaround I ended up using was:

let fileTarget = 
    let ft = new NLog.Targets.FileTarget()
    ft.Name <- "logger"
    ft

But this is not as nice as having intellisense, where needed between the brackets.

yes, this is very irritating. Hope it will be fixed

I think the specific request here is that "Name" be shown as a completion when pressing ctrl-space at positions like:

 let fileTarget = new NLog.Targets.FileTarget( $

 let fileTarget = new NLog.Targets.FileTarget( Na$

 let fileTarget = new NLog.Targets.FileTarget( $ )

 let fileTarget = new NLog.Targets.FileTarget( Na$ )

 let fileTarget = new NLog.Targets.FileTarget( Na$ = "logger" )

and all the same when the "new" is not present. I agree this is a major missing piece of functionality in intellisense and has an impact on how you end up writing code.

One problem is that there the intellisense list shown at the plain "$" positions above will still be long (all in-scope identifiers, namespaces etc.), since a lot of things can still be written at those locations. But still, some intellisense help would be appreciated.

And also in multi-argument versions of the same.... e.g.

 let fileTarget = new NLog.Targets.FileTarget(foo, $

let fileTarget = new NLog.Targets.FileTarget(foo(), Na$

let fileTarget = new NLog.Targets.FileTarget(foo(), $ )

let fileTarget = new NLog.Targets.FileTarget(foo(), Na$ )

let fileTarget = new NLog.Targets.FileTarget(foo(), Na$ = "logger" )

>>but NOT on the rhs of the "=" here:
>>```fsharp
 let fileTarget = new NLog.Targets.FileTarget(Name = $
 let fileTarget = new NLog.Targets.FileTarget(Name = $ )
 let fileTarget = new NLog.Targets.FileTarget(Name = Buz$
 let fileTarget = new NLog.Targets.FileTarget(Name = Buz$ )
 let fileTarget = new NLog.Targets.FileTarget(foo(), Name = $ 
 let fileTarget = new NLog.Targets.FileTarget(foo(), Name = $ )
 let fileTarget = new NLog.Targets.FileTarget(foo(), Name = Buz$ 
 let fileTarget = new NLog.Targets.FileTarget(foo(), Name = Buz$ )

I agree this would be nice to fix.
There is a handy workaround (which might qualify as a bug itself...): type "." in the ctor call and an intellisense list pops up containing only members of the type being constructed. You have to go back and delete the . character later, but it's helpful from a UI perspective.

This is a feature suggestion not a bug - we have never supported intellisense completions here (though it would be very, very useful to do so).
