Why mix .Net Standard and .Net Core projects in one solution? -


i started working through apress "building web applications visual studio 2017". @ beginning setting projects. set solution called spystore. .net core console app called spystore.dal. .net standard class library project called spystore.models.

my question why author choose .net standard class library on .net core class library. there difference?

what difference between .net standard , .net core. , there reason him mixing standard in of sudden?

you can visualize .netstandard set of apis. implemented multiple runtimes, netframework (net461, net47 monikers example) or netcore (netcoreapp) lib not executable, independant concreate implementation.

because may want use library in netframework project (or other implementation of .net standard), targeting netstandard make sure portable of these implementation, netcoreapp lib targetable netcoreapp project.

an app can netcoreapp or netcore, dependant of implementation of framework

you can find more infos here, , platform implements version of netstandard: https://docs.microsoft.com/dotnet/standard/net-standard

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
