i got request customer wants able type query string of web service parameters in ie10 address bar , service results. parameters include string in hebrew, like: http://mywebsite.com/service.asmx/foo?param1=123&param2=מחרוזתבעברית it looks me that ie10, unlike other (normal) browsers, won't encode query string parameters - every non-ansi character goes after ? mark turned '3f' byte, though encode goes before ? mark - url itself. for example, if try reach url (the parameter imaginary, url not, , have no connection site) http://www.shlomo.co.il/pageshe/sales/רכב-למכירה.asp?param=פאראם and in wireshark bytes send server, shows me you can see substitute hebrew part of url urlencoded string, substitutes hebrew parameters ?????, '3f's. the same string in chrome encoded in it's entirety: get http://www.shlomo.co.il/pageshe/sales/%d7%a8%d7%9b%d7%91-%d7%9c%d7%9e%d7%9b%d7%99%d7%a8%d7%94.asp?param=%d7%a4%d7%90%d7%a8%d7%90%d7%9d http/1.1 i tried o...

say have database of 50 tables. making change wording of 1 of columns relationship affects 20 of tables. how set migration? see @ least 3 possibilities a separate migration change on every table a single migration of them changing initial declaration of creation of tables. i'm quite confident 3 worst approach because cannot migrate have rebuild entire schema. i'm stuck between 1 , 2. 2 best approach because creating 1 migration 1 change happens affect lot of tables. i'm leaning towards. on other hand, feels messy. any resources on appreciated well. thanks it makes more sense go option 2. say take option 1 , x separate migrations. you'll end x migrations mess database's integrity, you'll have run them (or rollback them if want undo changes). if changes need made together, makes sense put them in same file

this question has answer here: why remove unused using directives in c#? 10 answers what difference between : using system; using system.collections; using system.collections.generic; using system.linq; using system.text; and using system; using system.collections.generic; does affect performance when adding "too much" references ? big applications, there difference removing useless references ? i mean, if use "using system" seems enough cover of requirements, why should specific adding specific references under system reference? thanks it's matter of code readability. yes, maybe right while you're writing code, know aren't using system.linq , presence doesn't bother you. after all, 1 day might use it, right? but day else going reading , maintaining code, or will, long enough afterwards you've forgotten c...
