@KevinRansom you and I talked about this in the hall and you said you know why this is reproducing. I don't quite recall the reason why...

[cartermp]

For posterity: @KevinRansom looked into this and it's awfully tricky with no quick fix. I don't recall the proposed solution. @KevinRansom?

[KevinRansom]

Yes, it is awful. I think I had a fix in mind, but then get randomized ... It will take a while to get back to it, I need to focus on F# 4.5 for a while. I will try to get a fix in for Dev 15.8. No promises though.

[baltie]

It might seem benign, and it is in many ways I guess, but it makes VS show yellow triangles on dependencies in all projects that reference an F# project right now. Which makes the yellow triangle pretty useless for tracking down actual dependency issues. I really hope you can get this fixed before 15.8, which is probably months away.

Also saw this issue. Please help address it.

VS 15.7.2

[cartermp]

This should now be fixed with #4990

@KevinRansom is this pending a CLI insertion to light in the tools?

[YunWeiaa]

Repro on d15.7/27703.2031.

[cartermp]

@YunWeiaa I would expect this to continue to reproduce with 15.7 builds, as I don't think we've serviced the fix. It should no longer repro on d15.8 builds, though.

[YunWeiaa]

Got it. Thanks.

[BenjaminHolland]

Is there a fix for this, or do we just have to wait for a VS update?

[KevinRansom]

@BenjaminHolland , it's fixed in VS2017.8 preview 3. We will not be patching vs2017.7.
