I am using ASP.NET MVC4 deployed on WebApps, EF6, Azure SQL Database
I have two connectionstrings, one direct to the DB and one that is needed as I am using Entity Framework. If I setup the first via Azure and leave the EF string in web.config, all works fine. Once I try to move the EF connectionstring to Azure, it breaks.
I have tried to follow all the posts on how to setup an EF connection string in Azure Management Portal, and the advice seems to be to use the following:
In Management Portal:
Name:
EFConnectionString
Value:
metadata=res://MyModel/model.csdl|res://MyModel/model.ssdl|res://MyModel/model.msl;provider=System.Data.SqlClient;provider connection string="Data Source=tcp:myserver.database.windows.net,1234;Initial Catalog=mydatabase;User ID=Admin#myserver.database.windows.net;Password=12345678"
SQL Database:
Custom
Note:
" is replaced by " in the Azure string.
In Web.config I still need the following:
<add name="EFConnectionString" connectionString="" providerName="System.Data.EntityClient"/>
I have changed certain details in the connectionstring for security reasons, but the true string does work fine in Web.config.
However when I do attempt the above, I get :
The page cannot be displayed because an internal server error has occurred.
Further Log error message:
The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid.
Any help appreciated. I am trying to do this to enhance the security of stored passwords for accessing DB on Azures, as I understand that setting them up via the portal encrypts them.
Thanks.
First check your deployment. I've run in a similar problem, and after a couple of hours struggling I found out that I was deploying without actually sending connection strings, falling back to whatever was in the portal config... the others keys in the we.config were being sent over, but the conn strings weren't... after I properly set it up on the portal, everything went back to normal...

I have been developing an application locally using asp and entity framework to interact with my database. I am using a model first approach. I want to deploy this app to Azure but I keep getting the error "Keyword not supported: 'metadata'."
Through searching and reading posts like this: Windows Azure, Entity Framework. Keyword not supported: 'metadata'.
I know its an issue with my connection strings but i can't figure out what i'm doing wrong.
Connection string in my local web config:
<add name="BeCivicData" connectionString="metadata=res://*/Models.BeCivicData.csdl|res://*/Models.BeCivicData.ssdl|res://*/Models.BeCivicData.msl;provider=System.Data.SqlClient;provider connection string="data source=.;initial catalog=BeCivic;integrated security=True;multipleactiveresultsets=True;application name=EntityFramework"" providerName="System.Data.EntityClient" /></connectionStrings>
Generated Connection String for the Azure DB:
Server=tcp:becivicserver.database.windows.net,1433;Initial Catalog=BeCivic;Persist Security Info=False;User ID={MyID};Password={MyPass}5;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;
On the Azure Applications settings page i have defined my connection string as both of the above which didnt work so i tried combining them to have the EF meta data (below) but the Azure connection string and that also gave me the Meta Data error:
metadata=res://*/Models.BeCivicData.csdl|res://*/Models.BeCivicData.ssdl|res://*/Models.BeCivicData.msl;provider=System.Data.SqlClient;provider connection string="Server=tcp:becivicserver.database.windows.net,1433;Initial Catalog=BeCivic;Persist Security Info=False;User ID={myid};Password={mypass}5;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" " providerName="System.Data.EntityClient"
In my application the EF .edmx file is in a folder named Models.
Both the database element and the code elements deployed separately to azure successfully and now i just need to link them up.
Keyword Not Supported:metadata
When you attempt to use the the connectionstring within the Azure Portal Connection Strings setting, it will get the above error.
So, try to change the type from SQLAzure to Custom.
You could refer to this article to troubleshoot.
To avoid parsing the connection string yourself, you can use the EntityConnectionStringBuilder class the parse the string and retrieve the database connection string from its ProviderConnectionString property.
I have a site running n Azure, which uses EF Database First model.
If I embed the connection string in the web.config and deploy all is rosy.
<add name="MyEntities" connectionString="metadata=res://*/App_Code.Model.csdl|res://*/App_Code.Model.ssdl|res://*/App_Code.Model.msl;provider=System.Data.SqlClient;provider connection string='Data Source=my.database.windows.net;Initial Catalog=myTest_DB;User ID=***;Password=***; MultipleActiveResultSets=False'" providerName="System.Data.EntityClient"/>
But, I don't want the connection string in the web.config because it contains credentials.
So I moved it to the connection string area in Azure Properties.
First issue I hit is getting metadata invalid keyword error.
I solved that by changing the type from SQL Database to Custom.
However, I now get this error:
The connection string 'MyEntities' in the application's configuration
file does not contain the required providerName attribute."
I've trawled the web and tried many variations of the connection string but not yet found the correct one.
Note: I guess I could make this an app setting and move the initialisation of the string to code, but even if only for curiosity sake I would like to know how to do it via the portal.
The problem is not the connection string, but the inability to specify the providerName from the portal.
Try publishing with a local or dummy connection string in place, and overwriting it as you have in the Azure Application Settings. See this answer: https://stackoverflow.com/a/18964294/94853
I have a ASP.NET MVC application which uses EF (v6) as data access layer. My application works fine on IIS Express and also when deployed to the server running IIS 7.5.
The problem is that I'm getting the following exception when I deploy it to Azure (Web Sites).
Code generated using the T4 templates for Database First and Model First development may not work correctly if used in Code First mode. To continue using Database First or Model First ensure that the Entity Framework connection string is specified in the config file of executing application. To use these classes, that were generated from Database First or Model First, with Code First add any additional configuration using attributes or the DbModelBuilder API and then remove the code that throws this exception.
I've searched the web and I made sure my connection string starts with "metadata=" + checked my db context class' constructor to be sure it contains the correct name (in my case it's "name=PsDataEntities"))
My connection string looks like this: <add name="PsDataEntities" connectionString="metadata=res://*/PsDataModel.csdl|res://*/PsDataModel.ssdl|res://*/PsDataModel.msl;
provider=System.Data.SqlClient;
provider connection string="data source=SERVER_NAME;initial catalog=DB_NAME;user id=UID;password=PWD;
MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
Anybody had the same problems?
Any help is appreciated
I did a few more tests (like changing metadata in the connection string to use fully qualified names instead of '*') without success, then I decided to set my metadata (regarding .csdl/.ssdl/.msl) programatically with the help from this post. Application now works correctly when deployed to Azure.
I finally figured out how to get web.config transformations working, so that locally I have one connection (the one in my default web.config), and then when I publish to Azure, the "debug" transformation is applied so that an Azure-SQL database connection string is used.
That much is working, but now I'm running into a problem with database migrations.
In my Configuration:
protected override void Seed(MG.Context.MentorContext context)
{
System.Data.Entity.Database.SetInitializer(new MigrateDatabaseToLatestVersion<MentorContext, Configuration>());
if (!WebSecurity.Initialized)
WebSecurity.InitializeDatabaseConnection("DefaultConnection",
"User", "UserId", "Username", autoCreateTables: true);
}
Now, when I'm running locally and want to update my local database, I open up Package Manager Console and type in 'update-database' and everything works wonderfully.
Sometimes I want to update the remote Azure-SQL database though - so in the past I've done this:
Update-Database -ConnectionString "azure connection string here" -verbose
which was working when I was manually updating my local web.config. Now that I'm using the above transformations, even though I specify a connectionString, DefaultConnection in my Seed method resolves to the un-transformed connection string (my local db), so the Membership tables never get created on the Azure database.
This can be solved by manually updating the default web.config, but that defeats the purpose of using these transformations.
How can I have these transformations applied so that the Seed method of my EF migrations uses the Azure connection strings - OR - how can I tell update-database to use the azure connection string?
I'm trying to avoid manually swapping the connection strings if I can.
You mention a Web.config and "publishing" to Azure; are you using Azure Web Sites?
If so, look at this article. In short, if you configure a connection string on the K/V store of Azure Web Sites with the same name as your connection string, the value you set on Azure will automatically take precedence:
Connection strings work in a similar fashion, with a small additional
requirement. Remember from earlier that there is a connection string
called “example-config_db” that has been associated with the website.
If the website’s web.config file references the same connection string
in the configuration section, then Windows Azure
Web Sites will automatically update the connection string at runtime
using the value shown in the portal.
This should ensure that you Seed method attempts to connect to the right database.
I am using SQL Server CE 4.0 with WebApi on Windows Azure Websites. I have been successfully able to deploy SQL Server CE. The weird problem I am facing is that my site is able to log me in using the same DB but I am not able to use any of the controllers to fetch the data.
I am using same connection string for both. The only difference is that for logging in I am using WebSecurity as I have enabled OAuth on the site.
Can someone throw some light on how to debug and fix this issue? The error I am getting for the calls is
Format of the initialization string does not conform to specification
starting at index 0.
However the same string works for authentication, change password, adding OAuth connections etc.
Thanks in advance
I connected to the site using FTP. I was not giving the site name as domain name and it was denying me access earlier. On connecting, I got hold of the Web.config file and I found something interesting. While publishing the site, the web.config was modified to add another connectionstring with the name of context_DatabasePublish.
This string had following details connectionString="ContextName_DatabasePublish.ConnetionString" providerName="System.Data.SqlClient"
Also there was a new section called context added to the entityframework section of the config file with all the details for the context to use but again pointing to same connection string. The provider it is using is sql and not sqlce. I believe that is the reason it was failing.
I uploaded my normal config file and the site started working. I need to explore more on to why and how the new connection string got added. I will post the details in comments.
