In the machine.config on one system we have:

However DbProviderFactories returns nothing. Not even the OleDB or ODBC providers. The app.exe.config file has no section and therefore no .
What can be blocking this?

We decided to migrate from SQL Server Compact to SQL Server Express (possibly LocalDB) as Compact is no longer supported and we believe Express is more feature rich and likely performs better.
I made the changes necessary (although clearly missed something :) ) and the database is recreated as an .mdf file. The problem seems to be when the database is accessed. I get the error I have pasted below. The upshot is that somehow, somewhere I seem to have a reference to a provider with invariant name System.Data.SqlServerCe.4.0 when I have no intention of doing so.
I have done research and found these two relevant posts, which are not fully answered:
MVC app erroring on SqlServerCe.4.0 provider after converting to Sql Express
and
Entity Framework using the wrong connection provider
I have tried deleting the migrations and have modified the app.config file. I have also deleted on references to SQL Server Compact from the project references. What else should I be looking at? I'm tearing my hair out over this one.
What other information can I provide?
Thanks,
Dave
P.S. Another way to ask the question would be pointing out that https://stackoverflow.com/users/183934/erikej commented in the links above:
"Obviously you reference sqlce somewhere, either in .settings or in code based configuration DbConfiguration class... – ErikEJ Sep 13 '14 at 6:09 "
Where are all possible places that Compact could be referenced?

Except for the commented out sections, I do not believe I am mentioning SQL Server Compact!
ADDITIONAL INFO IN RESPONSE TO COMMENTS 2
The configuration string used is pulled from a .json file and looks like this:
LocalDbConnection:
Server=(LocalDB)\\MSSQLLocalDB;Integrated Security=true;Initial Catalog=Vax3
Previously I was using:
Data Source=C:\ProgramData\TruMed\AccuVax\AccuVax.sdf;
Clearly there is some concern I'm using the wrong connection string and/or adapter as I'm getting messages about SQL Server Compact. I have searched the code for AccuVax.sdf and have not found any instances. Again, database is created no problem; the problem seems to be accessing it.
We also had the same problem. We tried to migrate from SQL Compact to SQL Express. We chased and removed any reference to SQL Compact in the solution but that was not enough.
Our final move was to clean completely the solution (any visual studio that are not needed to open the solution):
remove obj, debug, release...
remove .vs folder (that's probably the one)
Finally we reopened the solution, tried again and got it work.
Hope it helps.
Before I begin, existing questions here and here do not solve my problem.
I am using SQLite with EF6, with package SQLite.CodeFirst used to generate my db schema as required. I am running unit tests on my repository class which uses the DBContext on the backend, but the database needs to be cleaned up before running each test such that subsequent tests are not corrupted.
My problem is that when I call dbContext.Database.Delete() I get the following exception:
System.Data.Entity.Core.ProviderIncompatibleException was unhandled by user code
Message=DeleteDatabase is not supported by the provider.
Source=EntityFramework
I want to avoid trying to having to discover the location of the database and deleting it from disk as the location varies depending on application. Has anybody got any suggestions?
Here are excerpts of relevant parts of my code:
App.config

It means that the System.data.Sqlite EF provider does not implement the Deletedatabase method (part of Migrations, which is not implemented either). The Devart provider (not free) adds proper support: https://www.devart.com/dotconnect/sqlite/features.html#ef
error 0175: The specified store provider cannot be found in the configuration, or is not valid
I am using Entity Framework Code-First Migrations and everything is great locally.
My DB is SQLServer 2008. (Also using SQL CE for local development)
I can use the live SQL Server db connection string locally with no problem.
Here is the Migration code in _appStart.cshtml:
#using EF = System.Data.Entity;
#using TCommon = Told.Web.Common.Logic;
#{
// Manually initialize
var initializer = new EF.MigrateDatabaseToLatestVersion<TCommon.CommonContext, TCommon.Migrations.Configuration>();
System.Data.Entity.Database.SetInitializer(initializer);
initializer.InitializeDatabase(new TCommon.CommonContext());
// DB Maintenance
TCommon.AppUserLogic.CleanDatabase();
// Asp.Net
WebSecurity.InitializeDatabaseConnection("ToldDB", "UserProfile", "UserId", "Email", true);
// Common
TCommon.AppStart.Run();
}
This works great locally. Either against a SQL CE or against my live database. It ran fine locally to migrate my live database to the latest version.
However, when I put it on my web server, it throws this exception:
Exception
Server Error in '/' Application.
Schema specified is not valid. Errors:
(0,0) : error 0175: The specified store provider cannot be found in the configuration, or is not valid.

System.Data.Entity.Migrations.DbMigrator.Update(String targetMigration) +456
System.Data.Entity.MigrateDatabaseToLatestVersion`2.InitializeDatabase(TContext context) +64
Now, this has something to do with the migration attempt. So when I wrap the migration call in a try-catch block, I can use the database fine (because I migrated the live db locally).
#using EF = System.Data.Entity;
#using TCommon = Told.Web.Common.Logic;
#{
// Manually initialize
var initializer = new EF.MigrateDatabaseToLatestVersion<TCommon.CommonContext, TCommon.Migrations.Configuration>();
System.Data.Entity.Database.SetInitializer(initializer);
try
{
initializer.InitializeDatabase(new TCommon.CommonContext());
}
catch (Exception ex)
{
}
var db = new TCommon.CommonContext();
var test = db.AppUsers.FirstOrDefault();
// DB Maintenance
TCommon.AppUserLogic.CleanDatabase();
// Asp.Net
WebSecurity.InitializeDatabaseConnection("ToldDB", "UserProfile", "UserId", "Email", true);
// Common
TCommon.AppStart.Run();
}
What would be causing the migration diff-check to fail when I try to run it on my web server?

I have now found the answer:
Make sure that you install these nuget-packages:
Microsoft.SqlServer.Compact and
EntityFramework.SqlServerCompact
Deploy again, and make sure that SQL Server CE is now in the \bin-folder (the folders x86 and amd64 with all the files).
And also these files must be in the bin-folder:
System.Data.SqlServerCe.dll
System.Data.SqlServerCe.Entity.dll
Make sure it is the right version. The ones that are installed with SQL Ce did not work, it must be the ones from the nuget package.
Also make sure the Web.config contains this:
<system.data>
<DbProviderFactories>
<remove invariant="System.Data.SqlServerCe.4.0" />
<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>
And this:
<dependentAssembly>
<assemblyIdentity name="System.Data" publicKeyToken="b77a5c561934e089" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>
Note that you have to do this no matter if you use SqlCE on the production server. I am not sure you need the bin-files for the database itself, though.

I have checked the Application log in the event viewer but nothing in there... please help!
Since you are logging to the Windows Event Log, the event source must be registered with the operating system before you can successfully log using it. Normally the .NET framework will automatically create event sources the first time you use them, but creating event sources requires administrator privileges. You can run the app as admin once and get it registered or search MSDN for "registering event sources".
I am using Database TraceListener for logging. I've executed the CreateLoggingDb.cmd and the Logging Database is in place. My web.config looks like the below.
When an excpetion occurs I try to log it as below.
ExceptionPolicy.HandleException(ex, "PayrollException");
The code runs but it does not log in the database table. Please let me know if the settings in web.config are not correct or the procedure for logging has to be different.

A few places to start looking are:
Did you use EntLibConfig.exe to build the web.config? This is an exe that comes with Enterprise Library, you should find it in the Bin directory of the Enterprise Library install in Program Files - it gives you a reasonably intuitive graphical interface to set up enterprise library for an application: just point it at the config file for your application and set up the things you want.
For database logging you need to configure your connection strings using the Data Access Application Block - you will need another section in your config file for this.
For your database connection string, what authenticaion mode are you using? Does the user identity running the application have write access to the logging database?
Do you have other database connectivity?
Also - if you are running the .Net framework 3.5 you should consider using version 4.1 of the Enterprise Library.
EDIT after config file supplied
Looking at the config file you've attached (you may want to remove the passwords by the way) I think that you are missing a logging exception handler - the only exception handler you appear to have is a wrap exception handler.
Below is an example of one of one of my exception handling policies (from 4.1 of the Enterprise Library but yours should be similar).
<exceptionPolicies>
<add name="Data Layer Policy">
<exceptionTypes>
<add type="System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
postHandlingAction="NotifyRethrow" name="Exception">
<exceptionHandlers>
<add logCategory="DataLayer" eventId="100" severity="Error" title="Data Layer Exception"
formatterType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.TextExceptionFormatter, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
priority="0" useDefaultLogger="false" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
name="Logging Handler" />
</exceptionHandlers>
</add>
</exceptionTypes>
</add>
</exceptionPolicies>
The wrap handler is used where you want to wrap one exception around another. You can have both a logging handler and a wrap handler if that is needed - the logging handlers fire before the wrapping ones.
