Hello,

first:

• the problem can be reproduced with Infragistics 15.2.20152.1000
• I attached a sample c# project that should compile after correcting infragistics dll references, with comments and a marked snippet where a breakpoint can be set to directly navigate to the issue

now to the problem:

• certain TSQL scripts cause a bug to occur when using TextDocument.Language = TSqlLanguage.Instance
• for those scripts, the SyntaxNode.SyntaxTree.Snapshot.GetText() returns garbage text at some point

The following is such a sample script. Without wrapping the case statement into brackets, or prefixing "name" as "rt.name", the .GetText function returns garbage after the code " and name in". With my breakpoint in the sample you can clearly see, that GetText returns "Y " instead of "BY" in the following nodes, and also the literals '123','456','789' are already split up in a weird way as in the span objects.

Thanks,
