I have built an asp.net webforms app with a DB which works great locally. I created a new context with an initializer class as they describe here. The DB is nicely seeded with my initial data onto localDB and everything runs beautifully. (Doing code first, no migrations according to the tutorial in the link above).
I have published my app to its online counterpart and everything seems fine until I enter a page which I know contains a context of my DB. At this point the database should be seeded as it successfully does locally however I just receive a time-out error. I suppose it is not connecting to my DB properly.
What is the proper method of publishing a webforms app and DB together to Azure?
Assume you are using Azure App Service (formerly known as Azure Website).
LocalDB is not supported see Using a LocalDb MDF file on Azure
please config your application to use remote database such as SQL Azure.

This works on my local machine but when I try to deploy to Azure, I get the following error:
I didn't even use code first, I used database first.
I created a simple ASP.Net Core application with user authentication (so all the Entity Framework has been preloaded into the web app template). It is connecting to my database with the connectionString that is located in my appsettings.json file, with "data source = {computerName}\\{serverName}" setup.
The database instance and Visual Studio are located on the same machine. This works fine in returning data to the web api while within development and debugging mode. When I publish it and try to go to the site from a domain name it does allow me to view the webpages that are not needing database connection but the rest that need data from the database returns pages like this:
Error.
An error occurred while processing your request.
Development Mode
Swapping to Development environment will display more detailed information about the error that occurred.
Development environment should not be enabled in deployed
applications, as it can result in sensitive information from
exceptions being displayed to end users. For local debugging,
development environment can be enabled by setting the
ASPNETCORE_ENVIRONMENT environment variable to Development, and
restarting the application.
I have tried to change the Environment Variables for ASPNETCORE_ENVIRONMENT from Development to Production to no success.
I have tried adding appsettings.Production.json to publishOptions in my project.json file, even though there is no file appsettings.Production.json, and this did not help. dotnet publish
Adding the evironment variable in the web.config file did not work Deployment
I need help getting the published web api to connect to my SQL Server database from outside the development Visual Studio setup.
The last thing I can think of is that maybe I am incorrect in how I understand the connection string. If the web api uses the connection string to connect to the database from the server-side then it should work just fine like it does when in development calling to http://localhost:port# since it's all on the same machine. But, if the database string needs to be based on a client-side call then it would have to be with domain names and IP addresses.
Can someone tell me which one it is?
The only thing else that comes to mind is that there is something I am not doing, and need to do, inside of IIS Manager. I see connect string there as well but unsure what that is for our does since the connection string is inside the application. Also maybe I am suppose to give the app some kind of authorization to communicate with the database server even though they are on the same machine???
After much research, finally googling "how to deploy a web api in iis" I was able to learn from Host ASP.NET Web API in IIS using Visual Studio Publish that I needed to add the security entity BUILTIN\IIS_IUSRS. Then placing a mapping to my database tables and giving db_datareader (and possibly db_datawriter) for the database to the IUSER to allow access from my self hosted IIS web api. This from the above mentioned link with the part stating
Accessing Database under IIS APPPOOL\ASP.NET v4.0
As we are using ASP.NET v4.0 App Pool make sure IIS APPPOOL\ASP.NET v4.0 is added to your Database Server -> Security -> Logins.
I'm working in VS2015 and have a ASP.NET Core solution with two projects - an API Web Project and a Class Library that holds all the data entities, context and Entity Framework migrations. The API project references the class library and all works well on my local machine.
I now want to deploy the solution to Azure and this is where I'm hitting the problem. If I right click on the API project and go through the Azure App Service publish wizard, on the Settings tab I expand Databases and the message is "No databases found for this project" - which I'm guessing is because it can't find a context as it's not in this project.
If I do the same on the CL project though, there is no Azure App Service deployment option, the only option is File System and clearly there's no option to create the database there either.
So, in summary, my question is how I can deploy this type of solution to Azure and have the database created and migrations applied?
I think you need to create the DB first in the azure and then try to publish your application through the wizard. The database is on your local machine and the application will work just fine on your local environment. But on the cloud you have to first create the database on Azure SQL. Then you need to get the SQL connection string from the portal and update your config file accordingly. Once this is done you can then publish your application from Visual Studio. Please note that the wizard will still not show you the databases, but the application, when configured properly will run fine.
I have a very simple app on my local machine that uses the ASP.NET membership provider. This works fine on my local machine.
I have published the app to our web server, and I need to know the specifics of setting up the application for asp.net membership to work.
I have a basic understanding that it uses an MDF file and somehow connects to a SQL database (SQLEXPRESS I assume on my local machine) which holds the user/role information.
I keep getting an error that it cannot connect to a SQL database when running the published application on the web server.
I wish to use a SQL server on a different machine (SQL69) than my web server (WEB69)
I have created a new connection string, but how do I tell ASP.NET to use it instead of the "LocalSqlServer" connection string that is created by default?
Can someone explain what is required to me?
Thanks for any help you can offer.
Use the ASP.NET SQL Server Registration Tool without any parameters to set up the SQL Server membership on your local machine. This will also update your config file:
http://msdn.microsoft.com/en-us/library/ms229862%28VS.80%29.aspx
You need to set up SQL Server DB membership on your local machine first. After you have this working, you can simply script the entire DB for your production environment. For this, you can use the Database Publishing Wizard in VS.
You can view a sample config file here:

I have created a website using asp.net 3.5.
And now I have added member support to it using Membership API and aspnetdb database.
And I have done all testing on my local machine.
Now, what issue needs to be considered with respect to aspnetdb while uploading this site to the server. ie; how this database will be available on the server side ?
Note : This is my first ever website.
I was just looking for an answer to this myself.
I've found the following that might help you:
http://www.studiocoast.com.au/knowledgebase/article-6-aspnet-using-sql-server-instead-of-aspnetdbmdf.aspx
"When developing applications in
ASP.NET 2.0, the default option for
roles and users is to use a local SQL
database in the App_Data directory.
This works fine locally, but will
bring up an error when uploaded to a
production server. To fix this the
ASP.NET membership information needs
to be stored in a dedicated SQL Server
database."
"ASP.NET includes a program called
Aspnet_regsql.exe which you can run
locally to configure your database.
More information on the program can be
found here:
http://msdn2.microsoft.com/en-us/library/ms229862.aspx"
Look in your C:\Windows\Microsoft.NET\Framework\v2.0.50727\ folder for the file InstallMembership.sql.
Thats the SQL script to create the database you need.
