asp.net mvc - Connection string EF Code First -


i started application using entity framework code first. in web.config added connection string: 

<add name="mycontext" connectionstring="data source=server\mssqlserver2008;initial catalog=dbname;persist security info=true; integrated security=sspi" providername="system.data.sqlclient" />

and received error when tried access controller: create database permission denied in database 'master'

so, debugged code , found attribute "connectionstring" inside context it's different web.config:

data source=.\\sqlexpress;initial catalog=myproject.models.mycontext;integrated security=true;multipleactiveresultsets=true;application name=entityframeworkmue

why connectionstring wrong??

in ef initialization code, make sure specify connection string name this

public class mydbcontext : dbcontext {     public mydbcontext() : base("mycontext") {} }

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
