Unable to Access RDS Database from Elastic Beanstalk Application

Hey everyone,

I ran into a bit of an issue today where I was unable to access my RDS SQL Express instance from my .NET Elastic Beanstalk instance. I was receiving the following error:

The server was not found or was not accessible.

The solution turned out to be fairly simply thanks to this StackOverflow post: http://stackoverflow.com/a/33207022/522859

Get your server instance security group:
– Log into AWS
– Navigate to elastic beanstalk
– Open your application instance
– Open configuration
– Open instances
– Find “server” on the page and copy the value in the “EC2 security groups” field

Add your server instance security group to your rds rules:
– Navigate to the RDS Dashboard
– Open your RDS instance
– Click on view details (left hand side or top)
– Find Security and Network
– Click on the rds-launch-wizard under security groups
– Click on inbound rules (very bottom currently)
– Add a new inbound rule with the copied security group as the source

Could not find part of the path ‘C:xlib’ – Adding new Web API Project

Hey everyone,

I ran into the following error when I tried to add a new Web API project in Visual Studio Express 2015 for Web:

Could not find part of the path ‘C:xlib’

The workaround for this was to temporarily unbind the project from TFS: File > Source Control > Advanced > Change Source Control > Click unbind on each of the projects

While not the same problem, this post helped me out: https://github.com/NuGet/Home/issues/1164

Cannot parse *.config file – AdaptivePayments SDK (PayPal)

Hey everyone,

Just working on a small project that uses PayPal’s C# AdaptivePayments SDK. I hit an error while attempting to make the following payment:

var service = new AdaptivePaymentsService();
payResponse = service.Pay(payRequest);
“Cannot parse *.config file. Ensure you have configured the ‘paypal’ section correctly.”

at PayPal.Manager.ConfigManager..ctor()
at PayPal.Manager.ConfigManager.get_Instance()
at PayPal.BasePayPalService..ctor()
at PayPal.AdaptivePayments.AdaptivePaymentsService..ctor()

It turns out that you need to add the following entries to your Web.config:


To get the account information you’ll need to do the following:
– Go to developer.paypal.com
– Login to your sandbox account
– Go to the dashboard
– Select accounts (from the list of all your sandbox accounts)
– Create a new one or select an existing business account
– Click profile
– Click API Credentials

Note that the steps required to get this configuration seem to change all the time. Hopefully this will be enough to get you on the right track.

TF30063: You are not authorized to access asxproject – TFS Online/Visual Studio

Hey everyone,

I ran into the following issue while trying to install the HTML Agility Pack via Nuget today:

TF30063: You are not authorized to access asxproject…

This fixed it for me:
– Go to “Team Explorer”
– Up the very top click on the “Connect to Team Projects” button (power cable looking icon next to the home button)
– Right click on the project and then click connect

Once connected, everything seemed to start working for me again. Check out this stackoverflow post more info: http://stackoverflow.com/a/16700451/522859

No Entity Framework provider found for the ADO.NET provider with invariant name ‘System.Data.SqlClient’ – MVC5

Hey everyone,

Just an error I came across while trying to use a new solution project:

No Entity Framework provider found for the ADO.NET provider with invariant name ‘System.Data.SqlClient’

The fix for this was simply to run the following command in the package manager console:

PM> Install-Package EntityFramework

Thanks to StackOverflow for the details: http://stackoverflow.com/a/18642452/522859

Change Default MVC5 Password Complexity Requirements – Passwords must have at least one non letter or digit character. Passwords must have at least one digit (‘0’-‘9’). Passwords must have at least one uppercase (‘A’-‘Z’)

Hey everyone,

I’ve started on a new MVC5 project and came across the following error message while trying to register a new user:

Passwords must have at least one non letter or digit character.
Passwords must have at least one digit (‘0’-‘9’).
Passwords must have at least one uppercase (‘A’-‘Z’)

While having a secure password is obviously important, I felt that most users would probably find these requirements a little extreme. After a bit of Googling I came across a StackOverflow post that mentioned a config class that you can use to edit these settings:

// App_Start > IdentityConfig.cs

...

// Configure validation logic for usernames
            manager.UserValidator = new UserValidator(manager)
            {
                AllowOnlyAlphanumericUserNames = false,
                RequireUniqueEmail = true
            };
            // Configure validation logic for passwords
            manager.PasswordValidator = new PasswordValidator
            {
                RequiredLength = 6,
                RequireNonLetterOrDigit = true,
                RequireDigit = true,
                RequireLowercase = true,
                RequireUppercase = true,
            };

View Generated SQL in Entity Framework (EF)

Hey everyone,

Just a quick post on how to view the generated sql in entity framework. To start with, just add the following line to your db context constructor:

public class TestDbContext : DbContext
    {
        public TestDbContext() : base("name=TestDbContext")
        {
            this.Database.Log = s => System.Diagnostics.Debug.WriteLine(s); //This line
        }
        ...

With this line added, you should now be able to see all of your generated sql in the output window.

SELECT TOP (1) 
    [Project1].[VidId] AS [VidId], 
    [Project1].[CreatedAt] AS [CreatedAt], 
    [Project1].[Check] AS [Check], 
    [Project1].[SourceCheck] AS [SourceCheck]
    FROM ( SELECT 
        [Extent1].[VidId] AS [VidId], 
        [Extent1].[CreatedAt] AS [CreatedAt], 
        [Extent1].[Check] AS [Check], 
        [Extent1].[SourceCheck] AS [SourceCheck]
        FROM [dbo].[Vids] AS [Extent1]
        WHERE [Extent1].[VidId] < @p__linq__0
    )  AS [Project1]
    ORDER BY [Project1].[VidId] DESC

-- p__linq__0: '535' (Type = Int32)
-- Executing at 28/06/2014 5:00:16 PM +10:00
-- Completed in 0 ms with result: SqlDataReader

If you’re not using EF6, there were a few other options where I came across this solution: http://stackoverflow.com/a/20751723/522859

Duplicate type name within an assembly. – Entity FrameWork (EF)

Hey everyone,

I ran into this error message while trying to debug a project today:

“Duplicate type name within an assembly.”

 

The workaround to this was actually pretty weird. Remove all of your breakpoints that appear before this exception and place one after it instead. That’s it!

A bit of a weird issue, but according to the StackOverflow post where I found the solution Microsoft are aware of it: http://stackoverflow.com/a/23529882/522859
