textDocument/foldingRange is not handled correctly

[fgreinacher]

Folding ranges are controlled through the capability textDocument/foldingRange. This capability is currently not deserialized correctly at the server side.

Given initialize params like this:

{
    // ...
    "capabilities": {
        // ...
        "textDocument": {
            // ...
            "foldingRange": {
                "dynamicRegistration": true,
                "rangeLimit": 5000,
                "lineFoldingOnly": true
            }
        }        
    },
   // ..
}

The OnInitialize handle will get a capability model like this:

OmniSharp.Extensions.LanguageServer.Protocol.Supports`1[[OmniSharp.Extensions.LanguageServer.Protocol.Client.Capabilities.FoldingRangeCapability, OmniSharp.Extensions.LanguageProtocol, Version=0.0.9.9, Culture=neutral, PublicKeyToken=6d868dff454e6022]]
[xUnit.net 00:00:03.04]       {
[xUnit.net 00:00:03.04]          IsSupported = 
[xUnit.net 00:00:03.04]       False
[xUnit.net 00:00:03.04]          Value = <null>
[xUnit.net 00:00:03.04]          ValueType = 
[xUnit.net 00:00:03.04]       OmniSharp.Extensions.LanguageServer.Protocol.Client.Capabilities.FoldingRangeCapability
[xUnit.net 00:00:03.04]       }

Can you estimate when this will be released?
