[lsoft]

Hi.

I know how to implement Roslyn based completion with context menu, where one can choose specific completion item and press Enter, like this:

Does anyone know how to extend in-line completion, like this:

In any case, thanks guys, you helped me a lot in my previous questions!

I found solution:

[Export(typeof(ProposalSource))]
[Name("ProposalSource")]
[Order(Before = "InlineCSharpProposalSourceProvider")]
[Order(Before = "Highest Priority")]
[ContentType("any")]
internal class ProposalSource : ProposalSourceBase
{ ... }

[Export(typeof(ProposalSourceProvider))]
[Export(typeof(ProposalSourceProviderBase))]
[Name("ProposalSourceProvider")]
[Order(Before = "InlineCSharpProposalSourceProvider")]
[Order(Before = "IntelliCodeCSharpProposalSource")]
[Order(Before = "Highest Priority")]
[ContentType("any")]
internal class ProposalSourceProvider : ProposalSourceProviderBase, IDisposable
{ ... }

csproj must be mef asset.
