VS 2013 C# and Git: .csproj files don't merge upon pulling -

-
me , friend working on project written in c# using vs 2013 express git ( not vs git plugin, mind you), , we're running problem. our workflow setup this: have central repository, , each have our own fork of repository work on separately. when our individual work done push central repository. when want sync central repository, pull. the problem when pull, csproj files randomly update. update , files have been added since last pull show in vs, , other times csproj file unaffected. it's strange because csproj gets updated everywhere else, including central repository, doesn't update when pull. in our .gitattributes file have .csproj set merge=union . the command perform when pulling git pull upstream upstream remote pointing our central repository. any ideas? i'll put in answer, based on edward thomson's comment , contains link merge conflicts in csproj files (haacked.com/archive/2014/04/16/csproj-merge-conflicts) . please note know nothing

Lucene 4.0: TermStats is not public in TermStats; cannot be accessed from outside package -

-
i have 2 questions regarding lucene 4.0: 1) change sorting in lucene, created own tfidf class , called termstats constructor ts[t] = new termstats( contents[t].field,contents[t].termtext, contents[t].docfreq, tfidf); but message termstats(string,bytesref,int,long) not public in termstats; cannot accessed outside package does know, whether not have way change it? 2) lucene, indeed, calculate tf*idf or term frequency (tf)? asking because have read term frequency contructor accepts docfreq related idf. any appreciated. thank in advance. 1 - generally, rely on lucene pass termstatistics objects computeweight method of custom similarity implementation, rather constructing them yourself. if need acquire them directly, accomplish calling indexsearcher.termstatistics (you'll need pass in appropriate termcontext call, created using static method termcontext.build ). 2 - yes, lucene's defaultsimilarity implementation of it's tfidfsimilarity

.net - Injection of ViewModels without a Service Locator -

-
i think service locator anti-pattern, find common see "viewmodellocator" each view takes datasource in xaml-based applications. how avoided? you can use mvvm framework uses conventions, caliburn.micro. in caliburn, register viewmodel di container when app starts. when have testview automatically bound testviewmodel (convention name, framework looks viewmodel in di container, gets/creates instance , binds it.).
