I'm using some 3rd party software that's failing. Their API is wrapped in a ASP web service.
The call stack tells me that it needs maybe MySQL.Data.DLL or something (not sure exactly) in the correct directory. So I'm wondering where that directory would be. The Web Server is IIS.
Here is the call stack:
Unable to find the requested .Net Framework Data Provider. It may not be installed.

I needed to copy MySQL.data.dll to the bin directory of my web service application directory. I also added the config key to the web.config.

I have coded a Web API in Ubuntu using .NET Core recently and I need to use database to store the application data so that I decided to use EF Core. I ran this project on Ubuntu machine and everything worked appropriately.
I've also tried to run it on my raspberry pi 2 but I wasn't lucky enough to make it work properly. I did the instruction on this website and got this output as soon as I tried to access the api/dooz on Firefox while accessing my RP through Remmina Remote Desktop.
If the problem is with the database, how can I include the .db file to the iDooz_1/bin/Release/netcoreapp2.1/linux-arm/publish folder to make it work?
How can I solve it?

However, api/values, the default API in the webapi application worked properly and I got the correct output as in I got earlier on Ubuntu.
NOTE: First, this project is generally made to build a Tic Toc Toe and to learn about REstful APIs using ASP.NET Core Web API. So, I made a database using Entity Framework called Dooz.db and that is in the main directory of the project. Second, I'm doing dotnet publish -c Release -r linux-arm because the .NET Core SDK is not available for ARM-Processors.
Third, this is the part of the code in which the terminal had output an error
at System.Linq.Queryable.Count[TSource](IQueryable`1 source)
at iDooz.Controllers.DoozController..ctor() in /home/c343/Documents/iDooz_1/Controllers/DoozController.cs:line 24
Here is the code:
public class DoozController : ControllerBase
{
public DoozController()
{
if(db.Players.Count() == 0)
{
db.Players.Add(new Player { PlayerID = 1, Username = "Alex123", Password = "1234", ProfilePic = "ProfilePics/Alex123.jpg" });
db.Players.Add(new Player { PlayerID = 2, Username = "Ashkan_007", Password = "12345", ProfilePic = "ProfilePics/Ashkan_007.jpg" });
.
.
.
db.SaveChanges();
}
}
.
.
.
You need to copy the database file into publish folder.

Check if you have a mapping for aspx... ideally you should see 2 mappings for .aspx...
you can also use the command line to get the info by the following:

I'm getting an Access denied error when I attempt to make a web service request. The web service requires an asymmetric security binding. The call is made via a webpage that references a .NET dll that references the web service. All of this works fine on our server but we loaded it up at a web hosting company we got hit with this error.
My theory is that whatever the GetKeyPairHelper method does it requires the ability to write a file to do it while we don't have access to the location it tries to write to. The support people at this company ran a trace for us and these were the last two lines:
06:03.1 w3wp.exe 5860 CreateFile C:\ProgramData NAME COLLISION >Desired Access: Read Data/List Directory, Synchronize, Disposition: Create, Options: >Directory, Synchronous IO Non-Alert, Open Reparse Point, Attributes: N, ShareMode: Read, >Write, AllocationSize: 0
06:03.1 w3wp.exe 5860 CreateFile C:\ProgramData ACCESS DENIED >Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, >Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a
Looks like something trying to write to C:\ProgramData but what? And why? And how do I get around it? I'm hoping there is some way to configure this so it doesn't have to write a file. Perhaps this job can be performed in memory or directed to an area we have access to.

writer.Close();
byte[] messageBytes = stream.GetBuffer();
int messageLength = (int)stream.Position;
stream.Close();
int totalLength = messageLength + messageOffset;
byte[] totalBytes = bufferManager.TakeBuffer(totalLength);
Array.Copy(messageBytes, 0, totalBytes, messageOffset, messageLength);
//maybe parse message around here...
ArraySegment<byte> byteArray = new ArraySegment<byte>(totalBytes, messageOffset, messageLength);
return byteArray;
}
What happened here is that the hosting company was hosting our site on a shared server and so rightfully denied access to the C:\ProgramData folder which, further down the directory contains C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys which is the folder you need access to in order to use certificates based security. Their solution for us was to allow access to this folder for our app pool only. Works like a charm.
I am following the Hubs Quick Start Guide in the Signalr Wiki. I get an error in Global.asax, Application_Start on the line RouteTable.Routes.MapHubs().
A route named 'signalr.hubs' is already in the route collection. Route names must be unique.

Maybe this is not needed anymore in 1.0.1? It worked fine in 1.0. It is also mentioned in the readme.txt from NuGet that we need the MapHubs command.

We've run into some issues with ASP.NET MVC 3 AntiForgeryToken HTML helper when having a custom configured MachineKey in Web.Config. The error is easy to reproduce if you change your MachineKey to the following (taken from Microsoft HowTo-guide on how to configure machine key).
<machineKey
validationKey="21F090935F6E49C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7

validation="SHA1"
decryption="AES"/>
The exception thrown by AntiForgeryToken is as follow:
[IndexOutOfRangeException: Index was outside the bounds of the array.]

Is this a bug in the ASP.NET MVC 3 Html Helper to generate the AntiForgeryToken? Or am I missing something in regards to configuring machine keys?
It looks like I screwed up the keys - using http://aspnetresources.com/tools/machineKey I was able to generate a valid machineKey config section.
