'Unable to load native components' error after deploying SQL CE 3.5 app with VS 2010

Posted By:      Posted Date: October 05, 2010    Points: 0   Category :Sql Server

Dev environment is VS 2010 on Win7 Ultimate 64-bit. Build configuration is x86 (32-bit). App runs fine in dev.

Then I build a Setup project for testing on a target machine. The target machine is a clean Windows XP Mode VM which (I believe) is 32-bit.

The app installs and starts fine on target machine, but then throws this error when it attempts to access the sdf database:

"Unable to load the native components of SQL Server Compact corresponding to the ADO.NET provider of version 8080. Install the correct version of SQL Server Compact. Refer to KB article 974247 for more details."

That KB article refers to 64-bit scenarios, which does not apply to my 32-bit Windows XP Mode target machine (my understanding is that Windows XP Mode is 32-bit even on 64-bit hosts).

In VS, the Setup and Deployment project seems to correctly include the .DLL as a detected dependency, and is including C:\Program Files (x86)\Microsoft SQL Server Compact Edition\v3.5\Desktop\System.Data.SqlServerCe.dll in the msi package. On the target machine, I've verified that this file is being installed into the target directory, along with the main executable. If I remove the file, I experience the expected error of being unable to load an assembly that can't be found, and then if I put it back, the "unable to load native components"

Error deploying workflow feature in VS 2010


Hi all,

I have a VS 2010 state machine workflow solution, and am getting errors deploying the feature.  It is a 2 part question:

1. The error is: "Error occurred in deployment step 'Activate Features': Feature with Id '8ebb19f1-c0cc-49be-9d48-f56d0c0cfdf8' is not installed in this farm, and cannot be added to this scope."  Here is my feature:

<?xml version="1.0" encoding="utf-8" ?>
<Feature Id="E7A6A9DB-FAA5-430E-8380-1C60A372879B" Scope="Site"
 ReceiverAssembly="Microsoft.Office.Workflow.Feature, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" 
 ReceiverClass="Microsoft.Office.Workflow.Feature.WorkflowFeatureReceiver" >
 <Property Key="GloballyAvailable" Value="true" />
 <Property Key="RegisterForms" Value="*.xsn"/>
 <ElementFile Location="ApprovalFormWComments.xsn" /> 

I added in the feature Id attribute just to try to resolve the error, but that didn't help as VS adds in the ID and scope automatically based on your settings in the feature designer window.

Desinger Workflow 2010: Unable to load workflow actions from the server. Please contact your server



I am facing a problem from last some days..

When I am trying to open/create/update workflows from Designer 2010, then designer giving me an error "Unable to load workflow actions from the server. Please contact your server administrator".

I researched on internet for this error and found some possible reason like


  1. Login user Permission issue
  2. Error in custom actions
So that I checked for permission for login user, but it has administrator rights. and I tried to open workflow by removing custom activity code, but still exist.

also if I tried to create/update workflow for another site on same server then it works without any problem.

Can anybody please help me?

Many thanks,

Error: "The document information panel was unable to load"





I have created a custom document content type that uses a specified word template for a sharepoint document library for contracts and offers, and added a few custom columns in the document library as well.

SharePoint 2010 backup is failing - Error - "Unable to read full interval from database - Operation



I am having a problem backing up a site collection, when trying to backup the collection I get the following error "Unable to read full interval from database" and "operation is not valid due to the current state of the object".

The backup does run and manages to backup 182MB of the site collection and then the backup fails, it fails at the same point what ever backup method I use e.g. STSADM, Powershell or Central Admin.

I'm getting the same error whether I use CA "granular backup" or "Farm backup", and using either STSAMD or Powershell. I can backup CA or the mysite collection but not the Home Portal site collection. I even tried installing the commuvaults 2010 agents and running a commuvault backup but this is also failing. i have included the log file entry below.

Does anyone have any suggestions on what i can do to either fix the problem or an alternative way to backup the collection or farm, I am currently taking a full SQL backup but am not sure how reliable this is as I haven't tried to restore the sites. 

P.S. I am not using the "UseSQLSnapshot" parameter.

SharePoint's Sandbox: Developing, Deploying and Monitoring Sandboxed Solutions in SharePoint 2010


The challenge in SharePoint development has always been the balance between creating and deploying solutions that you can trust not to damage or impair a SharePoint farm. A new feature in SharePoint 2010, called Sandboxed Solutions, enables farm administrators to feel comfortable that the SharePoint farm is safe, gives site collection administrators the authority to manage applications in their site collection, and provides developers with the flexibility to create solutions they know will be deployed in a safe and rapid manner.

Visual Web Dev 2010 error or new user error?


In a new web app, using the fresh new build, I added some fields that I wanted processed during login, i.e. common Profile stuff... added them to web.config.... sadly it appears that Studio 2010 will not automatically create a ProfileCommon class from ProfileBase, as previous studio web IDE's would do - that was frustrating for a bit, then I just created my own class... but that led to this interesting problem.

When populating the new profile attributes, the code behind class could not resolve any of the textbox referenced, all showed as not defined... figuring it was something simple, I kept going... added a customValidation control I needed, but though I double clicked the event in studio, and it dutifully created the stub code for me... the event never fired.

Determined to locate the problem I poored through forum entries and every reference I could (found lots of folks complaining about the profileCommon class stuff which is what led me to create my own class finally) -- but nothing specific to the problem I had of not seeing defined controls that were clearly there and working nor my customValidator control.

But... all of the code samples I saw - none had the ContentTemplate section... curious I removed that section, other items started to fail that were logical (header tags, etc.) but, my code behind section snapped back into order, intelisense n

Error Consuming Web Service - Unable to import binding xxx from namespace ...


In VS2008 / C# / ASP.NET 3.5, I wrote a test web service app. Here is an extract from the code:

namespace emed.MathWebService
    /// <summary>
    /// Sample Math Services For Learning Web Services Deployment
    /// </summary>
    [WebService(Namespace = " http://localhost/MathService")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    public class MathService
        public float Add(float a, float b)
            return a + b;


I have published this to an IIS virtual directory named MathService, and when I try to launch it with the URL http://localhost/mathservice/MathService.asmx is works fine and displays all the operations (Add, Subtract etc) in the service.

I then created a test web application in VS2008 (named WebSvcTe
