c# - Using roslyn for hover over data for source tree symbols -

question: how apply personal documentationprovider source tree symbols? type of symbol when use symbolfinder.findsymbolatposition()

specifically want override getdocumentationforsymbol() function. have overridden autocomplete symbols not symbols hover over.

background:

hi, using roslyn gather intellisense text editor creating. 1 of things need make quick info or tool tips. have working autocomplete suggestions. using snippet looks this

   compilation = csharpcompilation.create(         "myintellisense",         new[] { csharpsyntaxtree.parsetext(dotnetcode) },         assemblies     .select(i => metadatareference     .createfromfile(i.location, metadatareferenceproperties.assembly,     new dotnetdocumentationprovider(     new csharpcompilationoptions(outputkind.dynamicallylinkedlibrary)); 

this uses own personal dotnetdocumentationprovider parses xml , documentation way need it. works assembly symbols types of symbols have when use recommender.getrecommendedsymbolsatposition().

edit: wanted give more background :)

i symbols in 2 different ways.

1) 1 way when call

var symbols = recommender.getrecommendedsymbolsatposition(semanticmodel, offset, solution.workspace); 

i use when user asks auto-complete information these symbols can go through , each 1 call:

var information = symbol.getdocumentationcommentxml(); 

this calls function have overridden class documentationprovider :

protected override string getdocumentationforsymbol(string documentationmemberid, cultureinfo preferredculture, cancellationtoken cancellationtoken = default(cancellationtoken)) 

2) second way when user hovers on

var symbol = symbolfinder.findsymbolatposition(semanticmodel, offset, workspace, cancellationtoken); 

i call exact same function (from same line of code actually, keeping dry)

var information = symbol.getdocumentationcommentxml(); 

but not invoke overridden getdocumentationcommentxml() instead default roslyn 1 called.

thanks!

not finding of symbols need,how find more symbols using roslyn api

another question asked, when solved issue solved problem having here. problem thought

_workspace.currentsolution.addmetadatareferences(_currentproject.id,_compilation.references); 

updated workspace working in. not returns solution references added. needed use

_workspace.tryapplychanges(referencesolution); 

to save it. jason answering other question found @ link. if post here mark answer.
