Framedata provider

Dec 22, 2010 at 7:13 AM

Hi
I´m a total beginner at this, but are following the tutorial with no problem untill now.

I don´t get the connection to the database to work. Even if I try the complete music store I get the error, Framedata provider not installed.

I´ve searched on internet without any luck.

Can someone please point me in the right direction so I can countinou this great toutorial?!

Thanks

I've never seen a framedata provider error on ASP.NET. Can you copy the full error message here?

I´m not sure that this is what you wanted, but this error occur when I try to add the *.mdf file in App_data folder.

----

An error occurred while processing the local data file:
Unable to find the requested .net framework Data Provider. It may not be installed.

---

If I then press OK and continue to create the StoreDB.edmx I don´t have any connection as I should have according to the tutorial.

It sounds like you may not have SQL Server Express installed then. You can use another instance of SQL Server, or you can install SQL Server Express from here: http://www.microsoft.com/express/Database/

I think you need SQL Compact as well http://www.microsoft.com/sqlserver/2008/en/us/compact.aspx

You need SQL Compact for Version 3 of the tutorial and later. Part 1 now includes a section which lists the required software and how to get your workstation set up.

aholly - If you're working on the 2.1 release, all data access is against SQL Server Express. I'd recommend if possible that you jump over to latest release. There are save points from the end of each chapter so you don't have to start over. If you're stuck on the 2.x releases, we'll need to troubleshoot which database it's looking for and why it's not being found. Can you let me know what the <connectionStrings> section of your web.config looks like?

Jun 15, 2011 at 12:29 PM

Hi,

I'm getting the exact same error as aholly.  My connectionString is the same one you outlined in v.3:

<connectionStrings>

<add name="MusicStoreEntities"

connectionString="data source=|DataDirectory|\MvcMusicStore.mdf"

providerName="System.Data.SqlServerCe.4.0"/>

<connectionStrings/>

Thanks Jon.

@tgerman1029 - Your connection is pointing to MvcMusicStore.mdf, should be MvcMusicStore.sdf:

  <connectionStrings>
    <add name="MusicStoreEntities"
     connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf"
     providerName="System.Data.SqlServerCe.4.0"/>
  </connectionStrings>  

Jun 24, 2011 at 4:23 PM

Hi Jon,

 

Thanks for answering.  I made a mistake when I typed out the connection string, I am using the MvcMusicStore.sdf and not the .mdf and I still get the error.  Any suggestions?

  1. Make sure you have all the prerequisites installed. You can do that using this Web Platform Installer: http://www.microsoft.com/web/gallery/install.aspx?appid=VWD2010SP1Pack
  2. Run the completed project, which is included in the sample download. If you don't have it, you can grab it from http://mvcmusicstore.codeplex.com/releases/view/64379 - it's MvcMusicStore-v3.0.zip

Let me know if the completed project works. If it does, there's a problem with your project somewhere; if not, it's an installation problem.

I ran into this today. I have SQL Server Express 2008 RC2, but I don't use SQL Compact. I simply commented out the whole connectionString node in my web.config and everything started working:

 

  <!--<connectionStrings>
    <add name="MusicStoreEntities"
     connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf"
     providerName="System.Data.SqlServerCe.4.0"/>
  </connectionStrings>-->  

 

Since MvcMusicStore uses EF Code First, the DB is automatically created in SQL Express, as part of its conventions.

Hope this helps.

I have some problem like this, it's SOLVED when I comment connectionStrings in web.config

<!--<connectionStrings>
    <add name="MusicStoreEntities"
     connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf"
     providerName="System.Data.SqlServerCe.4.0"/>
  </connectionStrings>-->  
When I run, it's automatically create DB, name MvcMusicStore.Models.MusicStoreEntities
1. is there any explanation? on how to DB automatically created?
2. for what that connectionStrings in web.config is created?

I'm runnig from MVCMusic project solution that have been completed from codeplex

anyway, Thanks n Best Regards

Malik,

MVC Music Store used Entity Framework to access the database. EF uses a number of conventions to ease development. One of these conventions is that if a connection string is not explicitly specified, it will assume a default connection string based on a server name of ".\SQLEXPRESS" (this is SQL Server Express default instance name), with Windows integrated authentication, and a database name that matches the full class name (including namespace) of the DbContext class. In the this case, this is MvcMusicStore.Models.MusicStoreEntities. If the DB already exists, it will be used. If it doesn't, EF will create it for you.

there's a Model with the name MusicStoreEntities inherit from DBContext, cool, its will automatically create DB with this namespace include its tables

Thanks
