New to Azure and have difficulty to connect DB with webapp. I am playing with a demo project using entityframework and code first mitigation. It works as expected in my local computer and localdb. But it does not work when I try to deploy it to Azure. I use the Webapp and a SQLDatabase in Azure. Then, I try to connect them using connection string in Webconfig.
<add name="DefaultConnection" connectionString="Server=tcp:dritor.database.windows.net,1433;Database=dritorDB;User ID=****#dritor;Password={****};Encrypt=True;TrustServerCertificate=False;Connection Timeout=30" providerName="System.Data.SqlClient" />
The homepage shows up as expected. But when I try to fetch data from DB (I put some data with seed), it returns something as follows:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>
<Message>An error has occurred.</Message>
</Error>
I suspect that I made the connectionstring wrong but I am not sure. Any suggestions on how to debug in this situation would be appreciated.
The string looks correct except for the curly braces around the password. It should just be Password=****

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've had an Azure WebJob running for at least two years without any problems. The app.config contains the following...
<connectionStrings>
<add name="UniversalModelEntities" connectionString="dummy - the actual connection string is specified in the portal but for some reason we need this element here" providerName="System.Data.EntityClient" />
</connectionStrings>
And in the portal's Application Settings I have...
This has run without any problems... until this morning when I found the error
The connection string 'UniversalModelEntities' in the application's configuration file does not contain the required providerName attribute."
Everything I've found regarding Entity Framework connection strings in the Azure portal says that I should set that drop-down to Custom.
So what's the problem?
Furthermore, I've found that even if declare the full connection string in the app.config, I still get the same error message, which suggests that the problem lies in the portal's setting.
I managed to solve this problem by setting the drop-down option for the connection string to SQLAzure...
...which obviously results in an error, then changing it back to Custom...
Now the WebJob picks up the connection string correctly.
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 WorkerRole in Azure that's connecting to an MSSQL database (also in Azure, on its own virtual machine -- in other words not an Azure SQL database). The WorkerRole is using EntityFramework (code first).
My connection string looks like this and connections from the worker role works just fine in my development environment:
<add name="MyConnectionString" connectionString="Data Source=mydatabaseserver.cloudapp.net;Initial Catalog=MyDatabase;User ID=MyUser;Password=ThePassword;" providerName="System.Data.SqlClient" />
However, the application throws the error:
The connection string MyConnectionString in the application's configuration file does not contain the required providerName attribute
As you can see, it clearly does contain the providerName attribute. I have checked the obj/Release folder to see the actual configuration file that is published to Azure, and it does contain the attribute as well.
What am I doing wrong?
Never mind. It is in fact working now.
The reason I thought it wasn't working is that there is a delay in how Azure writes Trace data to TableStorage. This led me to believe that the WorkerRole was still throwing the error after updating the connection string, even though it wasn't.
I am using the code first method in my windows azure project. I would like to see wich tables are created by the framework but the mdf file is not listed in the app_data folder.
I tried editing the default connection string to:
<add name="ModelContext" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|ModelContext.mdf;User Instance=true;Database=ModelContext"
providerName="System.Data.SqlClient" />
When using this connection string I get the following error:
CREATE FILE encountered operating system error 5(failed to retrieve text for this error. Reason: 15105) while attempting to open or create the physical file 'C:\Users\Myname\WindowsAzureProject1\MvcWebRole1\App_Data\ModelContext.mdf'.
CREATE DATABASE failed. Some file names listed could not be created. Check related errors.
How can I solve this?
Any help is greatly appreciated.
This isn't the best way to do things. It is probably a permission problem. Take a look at this:
http://www.windowsazure.com/en-us/develop/net/tutorials/web-app-with-sql-azure/
It uses code first and works with Azure and starts out using SQL Express.
Sql Express is not installed in a web role. You need to use a Sql Azure database or add a start up task for the web role to install sql express. Take a look at this post from Steve Marx http://blog.smarx.com/posts/introduction-to-windows-azure-startup-tasks on how to add a start up task
