'Could not load file or assembly Oracle.ManageddataAccess' when I am not referencing it

I keep getting
System.IO.FileNotFoundException: 'Could not load file or assembly

error when I try to check for existence of a role. The problem is that have references to unmanaged data access"Oracle.DataAccess.dll" and none to managed!
I checked web.config and all the references and can't see where this managed data access reference is coming from. Any ideas?

Map Dictionary values to Entity object

I have an IEnumerable<Dictionary<string,string>> and I want to map it to an IEnumerable<Entity>. I was wondering what's the best way to do so?
E.g.
IEnumerable<Dictionary<string,string>> dictionary
where dictionary.Select(x=>x.Values.ToList()) which will give me the values I want to store/map to my entity object but the keys in the dictionary will tell it which entity to map to.
So I want to do something like if key == entityPropertyName, then insert value and I want to do that for the entire collection.
EDIT:
I tried this:
var serializer = new JavaScriptSerializer();
var csvToSave = serializer.Deserialize<entitiy>(serializer.Serialize(rows.ToDictionary(kvp=>kvp.Keys, kvp=>kvp.Values)));
But I get this issue:
Message :Type 'System.Collections.Generic.Dictionary`2[[System.Collections.Generic.Dictionary`2+KeyCollection[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Collections.Generic.Dictionary`2+ValueCollection[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' is not supported for serialization/deserialization of a dictionary, keys must be strings or objects.

System.Globalization.CultureInfo does not contain a definition for Name

I have this peculiar issue with the System.Globalization.CultureInfo class and the System.Globalization namespace. I'm returning an object (Languages) from an API call that has a CultureInfo property. I'm able to successfully pull this on the client side into an IENumerable<Language> languages {get; set;} but when I try to build with a line such as var x = model.languages.First().AssociatedCulture.Name I'm met with the following errors:
Error 489 'System.Globalization.CultureInfo' does not contain a definition for 'EnglishName' and no extension method 'EnglishName' accepting a first argument of type 'System.Globalization.CultureInfo' could be found (are you missing a using directive or an assembly reference?)
Error 488 The type 'System.Globalization.CultureInfo' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Globalization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
Here is the sequence of lines I have run to try this out:
var y = new CultureInfo("en"); //works
var z = y.Name; //works
var x = model.languages.First().AssociatedCulture.EnglishName; //error at this line.
I don't understand this phantom error. If it helps, the project that creates Language.cs uses the .NET portable v.4.5.
I have tried adding this to the web.config assemblies block but no dice.

Has anyone experienced this issue before? Is it somehow caused by .NET portable?

You need a project reference to System.Globalization.
When you edit the web.config file you're adding a reference for the dynamic assembly that's generated from your .aspx/.cshtml files, this is separate and distinct from your project references (which are references for the output DLL from your project).
Add a Project Reference in Visual Studio via Solution Explorer.

Problem accessing SQL Server from network share after reinstalling SQL Server

I have a problem, that is really driving me crazy.
First of all I must admit, that most of the work was done by a coworker, who isn't available anymore.
Before reinstalling the MSSQL Server rig, the whole thing looked like that:
Someone has developed a little .Net c# program which connects to the SQL Server, that is located on a different network share. Everything worked
We had to reinstall the server (Windows + SQL Server) and since that moment, if the program is run from that network share, I get the following error:
"Unhandled Exception:
System.Security.SecurityException:
Request for the permissi on of type
'System.Data.SqlClient.SqlClientPermission,
System.Data, ......"
If I run the programm locally from the computer where the shares are located, it works - so I guess all security issues where set right at the SQL Server. But there has to be a problem, because it worked correct before the reinstall.
Does this make any sense to someone? Or any ideas how to fix that?
Edit: Posted error message below. The program is called by a batch script.

this is a .NET-Security-Issue. It treats Apps from a Network-Share different than from a local folder.
Right now I am not sure how we fixed this in the past, but try the following: On the calling computer (not the server) set up a manual trust to this program (=Assembly) with the .Net-wizard from the control panel, using \server\share\program for navigation.
I think you can get it working with changing the Security-Levels/Zones as well.

Code Access Security and Sharepoint WebParts

This is correctly converted into a wss_custom_wss_minimaltrust.config when it is deployed onto the Sharepoint server and mostly works.
To get the WebPart working fully, however I find that I need to modify the wss_custom_wss_minimaltrust.config by hand after deployment and set Unrestricted="true" on the permissions set
<PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1">

It's all because I'm loading a User Control from the webpart. I don't believe there is a way to enable that using CAS but am willing to be proven wrong.
Is there a way to set something in the manifest so I don't need to make this fix by hand?
Thanks

Is your web part in the bin file?
Have you set partially trusted callers in the assembly?
If not do so! it's best practice.

Sometimes, it is hard to determine what permissions are actually being used when loading a usercontrol. Try granting unrestricted=true on the following list of security classes, and if you get it working, remove them one by one until you get the minimal set needed for your web part:

To setup cas look at the codeplex and see wspbuilder.
You won't need to do this manually.

As far as i know, there is no way you can apply custom cas for user controls. Dlls loading user controls should necessarily be in Gac or the web application Trust level need to be set to full.
Try avoiding user control if you need to put your dll in bin
