Two connection strings in web.config to one SQL DB work in debug but not when published

Question

I am trying to add asp identity to a very basic MVC site currently containing a singular table from a SQL database.

The SQL was added as a ADO.NET Entity Data Model, using EF Designer From Database and I can read and write without issue from my MVC site (both locally in development and after being published).

I then added asp.net identity and this added a local DB file which worked.

I then tried to migrate the identity tables across to my main SQL server so that I only have to maintain the one DB (both the hosting of the website and SQL DB are with the same provider).

I have managed to create the tables in the main SQL DB and have added a second connection string to my web.config to allow both asp identity and my existing edmx setup to work (if I try to run asp identity through the EF connection string I get the error "The entity type ApplicationUser is not part of the model for the current context."). I then removed the local DB files to be sure.

When testing on my client (with two connection strings) I can create accounts, login and out and use asp.identity as expected and can also see the identity tables in the main SQL DB being populated. I can also use my general EF connection for the core MVC site reading and writing of the DB.

However when I publish to the main site no matter if I call an identity or EF DB function I get the error

Error. An error occurred while processing your request.

which is displayed over / inline with the rendered page (I've tried turning on custom errors in the web.config but this doesn't appear to give me more details.)

My two connection strings can be seen below (I'm assuming this is where the problem is?) Do I need anything else in the web.config ? Or am I missing something fundamental?

<connectionStrings>
   <add name="BDIdentityString" connectionString="Data Source=IPADDRESS; Initial Catalog=DBNAME; User ID=USERNAME; Password=PASSWORD; Connect Timeout=60;" providerName="System.Data.SqlClient" />
   <add name="BDString" connectionString="metadata=res://*/Models.DBENTITYNAME.csdl|res://*/Models.DBENTITYNAME.ssdl|res://*/Models.DBENTITYNAME.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=IPADDRESS;initial catalog=DBNAME;user id=USERNAME;password=PASSWORD;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
 </connectionStrings>

UPDATE:

So I finally got custom errors to work (think I had a typo somewhere) and the errors are posted below. As a test I used a backup copy of my project to test again the EF DB queries without the introduction of identity - published it and tested it live. Again it all worked as expected. I then restored my current build with identity added and back to the same issue. (the connection string for EF has remained the same in both versions of the project)

For clarity I am using fasthosts.co.uk and in my testing I am doing this by reading and writing to the live SQL DB hosted with fasthosts from my client. As is the backed up version without identity when published to fasthosts is still able to connect and read / write to the SQL DB.

I'm using their Momentum package so have included a machineKey as required generated from a local IIS server I have. This key is present in both version 1 without identity and version 2 with identity.

I have also tried adding the following to AssemblyInfo.cs

[assembly: AllowPartiallyTrustedCallers]
[assembly: SecurityRules(SecurityRuleSet.Level1)]

(AllowPartiallyTrustedCallers being recommended by fasthosts for Security Exception Description type errors)

With the customerErrors off I get two different responses based on if I am calling the DB via identity or calling the DB from my EF calls in my MVC code. The errors are as such:

EF error:

Update 2

This could be a trust issue with fasthosts. I've just built a out of the box MVC site with identity enabled. Changed the connection string to point to the SQL DB - again works from development environment (with details registered from main project development testing) but fails when pushed live with no other changes.

I will endeavour to ask the hosting provider but am not 100% convinced this is my only / or actual problem as EF works without identity just not with identity installed in the project.

Answer 1

As expected the limitation was with https://www.fasthosts.co.uk/ - Moving my site with no code changes (other than the SQL connection string to reflect the new SQL server) with provider https://hostinguk.net/ the site worked without issue.
