  1. I am struggling getting my Website working with SQLServerCe 4.0.
    I am getting the following error message:
    [ArgumentException: Unable to find the requested .Net Framework Data Provider. It may not be installed.]
    System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName) +1420567
    System.Data.Entity.Internal.LazyInternalConnection.TryInitializeFromAppConfig(String name) +362

    System.Linq.Queryable.Count(IQueryable`1 source) +50
    Tips.Controllers.TipsController.InitWebData(WebData data) in TipsController.cs:146


    The connection-string I am using is the following:
    <add name="Tips"
    connectionString="data source=|DataDirectory|Tips.sdf;Persist Security Info=False;"
    providerName="System.Data.SqlServerCe.4.0" />


    Everything is working fine on my local machine.
    A different thread of this forum is suggesting to copy the binaries of SQLServerCe to the bin-Folder of my Website.
    I tried this, but without success.
    I copied the following DLLs (all from folder "Program files\Microsoft SQL Server Compact Edition\v4.0" on my Laptop with Windows 7 64 bit) to the bin folder:
    sqlceca40.dll
    sqlcecompact40.dll
    sqlceer40EN.dll
    sqlceme40.dll
    sqlceoledb40.dll
    sqlceqp40.dll
    sqlcese40.dll

    Is there anything missing or did I do something wrong in general?
    Thanks in adavnce!

    Are you receiving a new error message?
  3. Yes, the error message is the same.
    I started completely from scratch on the server side again, i.e.:

    • create new directory ("tips" in my case)

    • in VS2010 execute from menu Build --> Publish
    The only thing I found was, that the file-size of Program Files\Microsoft SQL Server Compact Edition\v4.0\Desktop\System.Data.SqlServerCe.dll is 465.248 bytes, whereas the one on the server (distributed via publish of my application) is 296.816 bytes.

    The current error-message looks like this:
    Server Error in '/tips' Application.
    Unable to find the requested .Net Framework Data Provider. It may not be installed.
    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  5. I checked your link. I copied all the required (as mentioned in the link). I still get the same error message.
    I really do not know, what I could do to get it running.
    My entry in web.config looks like this:
    <add name="Tips"
    connectionString="data source=|DataDirectory|Tips.sdf;Persist Security Info=False;"
    providerName="System.Data.SqlServerCe.4.0" />

    The DLLs on site are the ones from C:\Program Files (x86)\Microsoft SQL Server Compact Edition\v4.0\Private (the directories amd64 and x86) as well as the 2 DLLs from C:\Program Files (x86)\Microsoft SQL Server Compact Edition\v4.0\Desktop.
    The latter 2 I have copied directly to the bin-folder, the others are copied with the directory, i.e. they are located in bin\amd64 and bin\x86.

    I have no idea, which additional DLLs I could need.

    Oops. I missed this:

    Is there a URL we can view?
  8. The issue with the different sizes of the DLL I have fixed now. The one with 296.816 was the version 3.5.
    I changed my References to use version 4.0.

    The URL is http://www.club97.net/tips

    I have added the <system.web>-part to my web.config as suggested, but am still getting the same error-message.
  9. The bin-directory of my deployed webpage looks like this:

    I also checked with ProcessExplorer, if really the SqlServerCe Version 4.0 is referenced when starting the App on my Laptop:

  11. Thank you, now it's working.
    I added the following lines to web.config (the one located in the root dir):
    <system.data>
    <DbProviderFactories>
    <add name="Microsoft SQL Server Compact Data Provider"
    invariant="System.Data.SqlServerCe.3.5"
    description=".NET Framework Data Provider for Microsoft SQL Server Compact"
    type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=3.5.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/>
    <add name="Microsoft SQL Server Compact Data Provider 4.0"
    invariant="System.Data.SqlServerCe.4.0"
    description=".NET Framework Data Provider for Microsoft SQL Server Compact"
    type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/>
    </DbProviderFactories>
    </system.data>
