c# - Ambiguous Call Between Same Library? -

-

i attempting upgrade asp.net 5 project beta7 beta8. got runtime , switched various packages in project.json over. compiling, except i'm getting few errors have been unable resolve.

in particular, 1 has me stumped , preventing me going forward:

dnx,version=v4.5.1 error cs0121: call ambiguous between following methods or properties:  'microsoft.data.entity.sqlserverdbcontextoptionsextensions.usesqlserver(microsoft.data.entity.dbcontextoptionsbuilder, string)' ,  'microsoft.data.entity.sqlserverdbcontextoptionsextensions.usesqlserver(microsoft.data.entity.dbcontextoptionsbuilder, string)'

at line of code in startup.cs

services.addentityframework()         .addsqlserver()         .adddbcontext<mycontext>(options =>                      options.usesqlserver(configuration["data:defaultconnection:connectionstring"]));

i know in past, typically appears version of library in gac. however, don't believe case on osx. did check ~/.dnx/packages/ folder see if jumped out @ me, nothing there either.

here project.json reference (some parts trimmed):

{   "webroot": "wwwroot",   "version": "1.0.0",    "dependencies": {     "entityframework.commands": "7.0.0-beta8",     "entityframework.microsoftsqlserver": "7.0.0-beta8",     "htmlsanitizer": "2.0.5623.30465",     "imageprocessor": "2.3.0.0",     "microsoft.aspnet.antiforgery": "1.0.0-beta8",     "microsoft.aspnet.authorization": "1.0.0-beta8",     "microsoft.aspnet.diagnostics": "1.0.0-beta8",     "microsoft.aspnet.identity.entityframework": "3.0.0-beta8",     "microsoft.aspnet.mvc": "6.0.0-beta8",     "microsoft.aspnet.mvc.dataannotations": "6.0.0-beta8",     "microsoft.aspnet.mvc.taghelpers": "6.0.0-beta8",     "microsoft.aspnet.server.kestrel": "1.0.0-beta8",     "microsoft.aspnet.staticfiles": "1.0.0-beta8",     "microsoft.aspnet.tooling.razor": "1.0.0-beta8",     "microsoft.dnx.runtime": "1.0.0-beta8",     "microsoft.extensions.codegenerators.mvc": "1.0.0-beta8",     "microsoft.extensions.configuration.commandline": "1.0.0-beta8",     "microsoft.extensions.configuration.environmentvariables": "1.0.0-beta8",     "microsoft.extensions.configuration.json": "1.0.0-beta8",     "microsoft.extensions.logging.console": "1.0.0-beta8",     "system.net.http": "4.0.1-beta-23225"   },    "commands": {     "ef": "entityframework.commands",     "kestrel": "microsoft.aspnet.hosting --server microsoft.aspnet.server.kestrel --server.urls http://localhost:5000 --aspnet_env development"   },      "frameworks": {         "dnx451": {             "frameworkassemblies": {                 "system.drawing": "4.0.0.0",                 "system.runtime.serialization": "4.0.0.0"             }          }     },     trimmed here }

update seeing 1 set of warnings in dnu build might indicate possible problem.

check if nuget feed release , not develop branch (most problem) don't need feed

https://www.myget.org/f/aspnetcidev/api/v3/index.json

but think miss feed

https://www.myget.org/f/aspnetrelease/api/v3/index.json

check global.json beta8

"sdk": {   "version": "1.0.0-beta8"  }

check dnvm if set active dnx running beta8 before using dnu restore.

c:\git\dbc>dnvm list

active version         runtime architecture operatingsystem alias ------ -------         ------- ------------ --------------- -----    1.0.0-beta4     clr     x86          win    1.0.0-beta7     clr     x64          win    1.0.0-beta7     clr     x86          win             b7    1.0.0-beta7     coreclr x64          win    1.0.0-beta7     coreclr x86          win    1.0.0-beta8     clr     x64          win *  1.0.0-beta8     clr     x86          win             aa, b8    1.0.0-beta8     coreclr x64          win    1.0.0-beta8     coreclr x86          win    1.0.0-rc1-15838 clr     x86          win             rc1a

if has still has problems check invalid reference project.json.

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
