that's a rather difficult one :
I use Sandcastle Help File Builder to produce documentation for my C# project from Visual Studio 2010. I want to make code only visible for C# but in default there are also visible pieces of code for C++ and Visual Basic as shown on the screenshot :
How can I change this ? I mean here how can I change it in project creation options to produce only an .html for C#.
You can limit the syntax examples to specific coding languages by setting the Project Properties->Help File->SyntaxFilters property.
