i've several visual studio solutions. each solution has several projects generating assembly. all of these assemblies generated these projects. so, these assemblies loaded dinamically using 2 ways: referenced browsing assembly location (for example debug folder of each project). ninject (loading classes of whichever assembly containing classes implements interface). currently, when need debug code of these referenced or loaded assemblies, need generate exception of whichever assembly i'd step in, , visual studio, automatically shows me code. i figure out there way able navigate through code assemblies, i've absolutly no idea how that. you may open solutions @ once in several visual studio instances. then may start main process. in other vs instances select "attach process ... ctrl+alt+p" find process , attach then may set breakpoint in instance of vs.

this question has answer here: how compare strings in java? 23 answers for example, have 2 arrays: string [] arr1 ={"you", "book"}; string [] arr2 ={"do", "you", "like","book" }; i want check if arr1 match arr2 in terms of same order. if arr1 {"book", "you"} , arr1 not match arr2 . alright, think code wrong, anyway: for (int = 0; i<arr1.length; i++){ (int j=0; j<arr2.length; j++){ if (arr1[i] != arr2[j]){ return null; } } } but when run it, return null arr1 match arr2 . you can filter elements in array 1 aren't in array 2. result should match array 1. public static boolean withinandinorder(string[] a, string[] b) { return arrays.equals(a, arrays.stream(b) .parallel() .filter(...
