c# - Roslyn ImportAdderService doesn't visit trivia -

the microsoft.codeanalysis.editing.importadderservice.addimportsasync method visits non-trivia syntax nodes, , therefore doesn't add namespace imports them. leads results, cref's in xml documentation comments cannot simplified short names, when using microsoft.codeanalysis.simplification.simplifier.

the biggest problem have this, simplification can lead inconsistent results. assume have multiple cref's, , 1 cref, have namespace import (introduced due type, used in non-trivia node). then, 1 cref's gets shortened, , others don't.

for clarification.

before applying importadderservice , simplifier:

namespace namespace {   /// <summary>   /// <see cref=""system.collections.ienumerable"" />   /// <see cref=""system.collections.generic.ienumerable{t}"" />.   /// </summary>   internal class mydeclaration   {     system.collections.ienumerable field;   } } 

after applying importadderservice , simplifier:

using system.collections;  namespace namespace {   /// <summary>   /// <see cref=""ienumerable"" />   /// <see cref=""system.collections.generic.ienumerable{t}"" />.   /// </summary>   internal class mydeclaration   {     ienumerable field;   } } 

question

can work around issue? want add usings types referenced in cref tags.

or design?

i guess indeed missing feature, tell importadderservice visit trivia syntax nodes.
