c# - Can LocalDb and SQL Enterprise 2012 run side by side? -


i've installed sql enterprise 2012 , localdb appears inoperable. can access localdb command line , see instance referencing indeed running, when run project code first migrations enabled uses instance (localdb)\v11.0, error stating connection string may incorrect. didn't change connection string @ all, connection string set default while creating new project in visual studio 2012.

has had same issue? there fix running both side side?

here's exact error getting:

an error occurred while getting provider information database. can caused entity framework using incorrect connection string. check inner exceptions details , ensure connection string correct.

and exception:

system.data.providerincompatibleexception: error occurred while getting provider information database. can caused entity framework using incorrect connection string. check inner exceptions details , ensure connection string correct. ---> system.data.providerincompatibleexception: provider did not return providermanifesttoken string. ---> system.data.sqlclient.sqlexception: network-related or instance-specific error occurred while establishing connection sql server. server not found or not accessible. verify instance name correct , sql server configured allow remote connections. (provider: sql network interfaces, error: 50 - local database runtime error occurred. specified localdb instance not exist.

i realized issue was, helps else.

here section of web.config causing errors:

<entityframework>         <defaultconnectionfactory type="system.data.entity.infrastructure.localdbconnectionfactory, entityframework">           <parameters>             <parameter value="v12.0" />           </parameters>         </defaultconnectionfactory>         <providers>           <provider invariantname="system.data.sqlclient" type="system.data.entity.sqlserver.sqlproviderservices, entityframework.sqlserver" />         </providers> </entityframework>

the parameter v12.0 value issue. seems after installed sql server 2012, generated parameter went v11.0 v12.0 causing version conflict. guess have installed newest version of sql server express (2014) , not had problem @ since version number indeed v12.0.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
