Develop Reference

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

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="data source=IPADDRESS;initial catalog=DBNAME;user id=USERNAME;password=PASSWORD;MultipleActiveResultSets=True;App=EntityFramework"" 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.

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.

Asp.net Load Balancing Server Error

I am getting a null reference error on a asp.net application when it is on two Azure load balanced servers. When I turn off one the error goes away. When looking at the call stack there is not a real reason why a null reference has been thrown. I have even setup a remote debugging session on both servers and there is not a logical reason of why I am getting a null reference error. My gut says it works fine on one server but not when there is two so it must be a load balancing issue and I need to change my application setup to include load balancing. Is this a normal indication that something needs to change as far as application setup ? If so what needs to change? If not what other diagnostics can I run to get my application working on a cluster ?

It seems that your site is stateful, meaning that you are storing information on one server, so that if a user is sent to another server, that information will not be there. For instance, if you are using in-process Sessions, they will only exist on that one server.
Fortunately, there is a feature in Azure App Services that allows the user to be sent back to the same server each time.
Simply, turn on ARR Affinity setting under Application settings. This will ensure that the user is sent back to the same server on each request.

Asp.Net Mvc Web App PowerBI Login HRESULT E_FAIL Error

I am trying to have a single sign-in web app through azure that has an initial Microsoft login and then no second login. At the moment I am just trying to get 2 logins to work but when running locally I can get the app to work and show the Power BI reports using a dual login. But whenever I publish the app up to the Azure host and I try to access the power BI page instead of having a Microsoft popup to log in it just suffers from this error.

According to the exception, it seems that you application try to access to out-of-process COM in the WebApp, but it is restricted in the Web App sandbox.
If it is restricted in the WebApp and Cloudservice is possible, please have try to use Cloudservice. About how to Migrate and Publish a Web Application to an Azure Cloud Service from Visual Studio, we could refer to this document.

I am getting this error at the moment and I am pretty sure it has to do with the fact that my azure app does not have the "Access the directory as the signed-in user" permission, since I am accessing Power BI as a master user as in the" App owns data" scenario.
Notes:
I only get this error when I unwind the aggregate exception. Otherwise the error message is "One or more errors occurred." Here is a good link on that: Flattening of Aggregate Exceptions
It looks like I have the permission, and that I have the rights to grant it, but when I click on the Grant permissions icon I get an error message saying I cannot grant that permission myself.
In fact the Azure documentation is clear here that you can grant that permission yourself only for Application Type:Native App, not Web app/API which is what I have here (so the UI has a display bug). Here is a link to it:Permission Scope Docs
I am still trying to figure out who my "Admin" is so that I can get this permission, so I am not yet sure that this is the whole issue. Will update.

System.Globalization.CultureInfo.GetCultures returning null in dev environment (Visual Studio)

First of all, this could very well be a rookie mistake on my part, I'm fairly new to .net and c#.
I'm using the CMS system Umbraco on our latest project, and a recent update has meant the system has started using the System.Globalization.CultureInfo class to deal with localization. This has resulted in multiple "Culture Not Found" errors in the CMS back office that renders it unusable. Here's a stack trace from one of them:
Server Error in '/' Application.
Culture is not supported.
Parameter name: name
.-no is an invalid culture identifier.
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.

I'm still not completely sure where the .-no is coming from, but after some amount of research into this I tried running the following code with a breakpoint inserted:
var locale = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures);
This returned null, and doesn't seem to be throwing an exception anywhere. I'm guessing this might be the cause of the errors, judging by the stack trace. Could this be an issue with my local setup? I'm running Windows 10, mainly in a virtualization environment, but it can also run natively via OSX Bootcamp, where the problem still seems to be present. I've also tried using Powershell to output the list of installed cultures, and that works fine.
If it helps, I'm using IISExpress for the web server and the database is running under SQL Server 2016 Express.
Thanks in advance! Let me know if I can supply any extra info to help out with this.

Make use of the fact that Umbraco is open source.
Judging from the stack trace and exception details you have provided, problem is caused by this line:
https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Core/Services/LocalizedTextServiceFileSources.cs#L102
Apparently invalid value .-no is passed into GetCultureInfo method. If you look a bit up in the source code, it seems that this value comes from XML file name or XML file content.
I cannot provide complete solution for your problem, but here are some things to try to pinpoint root cause of it:
1) Clean deployment folder
Do full clean & rebuild cycle
2) Check localization XML files to check if they contain valid cultures
If you have edited files manually, make sure there is no typo there.
3) Compare folders of "fresh" install and your non-working solution folder
Check if update hasn't left behind some XML files from previous versions;

Cant find image in network drive

I know this question have been asking many times but none of then have solved my situation.
I have this simple code
Image f = Image.FromFile(#"\\NetWork\imagenes\folder0\1690D-PC.tif");
But it throws:
System.IO.FileNotFoundException \\NetWork\imagenes\folder0\1690D-PC.tif
I have total access to the related network
I do can find the image in that location. I copy the path, START + r, pasted the path and the image opens.
Is the same for all images in that server.
But the situation not only remains there:
I tested in another pc to checked if is was a IIS problem or
whatever, but when I tested it throws the same(2 pc cannot access to
that file, having they full access... weird...)
When im in development, I can find the image everything work normaly, but when i deploy and
upload to my local iis and the other pc, throw the related exception(FileNotFoundException).
My parner has the same code(almost the same proyect, just with some
diferrent functionality and public) and he can find the image and
display it.
I ran into this situation last friday and i havent came up with a solution yet.
Im willing to hear all your suggestions.
Update 2.
More info:
There are 2 more application that request images from that server and those application can find it normally. Those application are in my local IIS.
Updte

Have you tried using double back slashes instead of # to find the file? Might be worth trying.
Image f = Image.FromFile(" *FullPath* \\NetWork\\imagenes\\folder0\\1690D-PC.tif");
