I'm trying to add a reference to a project ("Geometry") that lives in another solution ("Bar Solution") into another solution ("Foo Solution"). Any project in Bar Solution (the home of the Geometry's source code) can import Geometry and use its features with no problem; however, when I add the DLL to Foo Solution, it imports fine, but the Object Browser shows it containing no namespaces or classes.
Has anyone experienced this problem or otherwise know of a solution? I can't find any information on SO or more generally, le Goog.
Object Browser of Foo Solution:
Bar's Solution Explorer:
Some code from Foo which is trying to use "Geometry":
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Geometry; // Error: "The type or namespace name 'Geometry' could not be found
// (are you missing a using directive or an assembly reference?)"
namespace Lever
{
public partial class LeverGUI : Form
{
public LeverGUI()
{
InitializeComponent();
}
}
}

I'm getting an error that says the name properties does not exist in the current context? The rest of the code seems fine, apart from this error, I'm aware there are similar questions however I'm struggling to apply the solutions in my own problem.

You don't have SQL_String property on your project. To add
Right click your project
Click on Properties
Go to Resources tab
Select Resource type string
In the grid Add SQL_String as Name of your resource name and provide value.
Your project namespace and class consuming that resource should have same namespace else you have to import that namespace in class.
I fixed this by adding a new dummy setting as follow:
then clicking the Save button. All errors saying "the name 'properties' does not exist in the current context" disappeared.
I am trying to write an extension method for the WPF Window class. I am doing it in a class library project in my solution, so that I can use it in all my projects in the solution.
Here is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
namespace ExtensionMethods
{
public static class MyExtensions
{
public static void ResizeToPrimaryScreenWorkingArea(this System.Windows.Window w)
{
}
}
}
When I try to compile this, I get the following error:
The type or namespace name 'Window' does not exist in the namespace
'System.Windows'
Yes, I DID add references to System.Windows and System.Windows.Forms in my class library project, and they are showing under References in the project in Solution Explorer.
What am I doing wrong?
Add PresentationFramework.dll reference to your project it contains the System.Windows namespace.

I know that this question has been already asked, but I cannot find anything that can help solve my problem.
I want to connect my aspx page (Retete.aspx) to a Microsoft SQL database. I'm getting this error on Retete.aspx.cs:
Error 1 The type or namespace name 'GlobalClass' does not exist in the namespace 'ProiectSera' (are you missing an assembly reference?)
The error points to this line of code:
ProiectSera.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
Where ProiectSera is the project name, GlobalClass is the file where I make the operation on the db.
My using statements are:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using ProiectSera;
The Target Framework is set to .net-4.5.
What should I do to solve this error?
Update
My GlobalClass.cs is:
using System;
using System.Data;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using System.IO;
using ProiectSera;
using System.Data.Services;
namespace ProiectSera.App_Code
{
public static class GlobalClass
{
static public void Update(string _param1, string _param2)
{//function to update}
}
}
App_Code is a folder where GlobalClass.cs is. I tried and
ProiectSera.App_Code.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text); //
but I had the same error. And I put the GlobalClass.cs in the project's root. I also removed the .App_Code from namespace ProiectSera.App_Code
UPDATE1
My Retete.aspx.cs is
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using ProiectSera;
using ProiectSera.App_Code;
namespace ProiectSera
{
public partial class Retete : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSave_Click(object sender, EventArgs e)
{
string intValRefTempSol;
string intValRefTempAer;
// intValRefTempSol = ValRefTempSol.Text;
// intValRefTempAer = ValRefTempAer.Text;
// ProiectSera.App_Code.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
}
}
}
Your GlobalClass is in the namespace ProiectSera.App_Code.
So the class name is ProiectSera.App_Code.GlobalClass
Make sure you don't have a ProiectSera class in the ProiectSera namespace also, otherwise if declaring using ProiectSera on top, it'll try to use it (as a general rule, don't name any class the same as your namespace).
If that still doesn't work, you may want to try using the global namespace:
global::ProiectSera.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
and see if that works: if it doesn't, and GlobalClass is in the same project, then there's something else you haven't shown us
Update
The only other thing that comes to mind, if you are positive that both files are on the same project/assembly, is that GlobalClass.cs is not being actually compiled. Make sure the Build Action is set to Compile (you can see the build action right clicking on the GlobalClass.cs in the solution explorer and selecting Properties).
If you are using VS.NET:
Right click on the References folder on your project.
Select Add Reference.
Select the .NET tab (or select the Browse button if it is not a .NET Framework assembly).
Double-click the assembly containing the namespace in the error message.
Press the OK button.
Ensure the following...
That you have a project reference to ProiectSera from your web application, if it's in a separate library. If GlobalClass is in the web application project itself, you won't require this, but if GlobalClass is defined in a separate library in the same solution or elsewhere, then you're going to need to add a reference to that external library in your web application.
Ensure that ProiectSera should not be ProjectSera (if it's a typo).
Ensure that you have your ProiectSera using statement in place at the top (using ProiectSera;). Assuming that this is the correct namespace. Check the namespace of your GlobalClass class and use that using accordingly in the class that wishes to use its functionality.
Then, simply call this in your code, assuming that Update is a static method of GlobalClass.
GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
EDIT: given that you've now posted your GlobalClass code, you can see that the namespace for this class is ProiectSera.App_Code;. So you need to have that as your using statement in the other class using ProiectSera.App_Code;. And then call it via simply GlobalClass.Update, as mentioned above.
If you don't understand how namespacing works in C#, then I recommend you check this out (https://msdn.microsoft.com/en-us/library/dfb3cx8s.aspx).
I am very new in C# (I came from Java) and I have the following problem
I have a solution that contains some project.
One of this project contain a class named CpeManager, this is the code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data;
using System.Diagnostics;
namespace DataModel
{
class CpeManager : MyManagerCSharp.ManagerDB
{
public CpeManager(string connectionName)
: base(connectionName)
{
}
public CpeManager(System.Data.Common.DbConnection connection)
: base(connection)
{
}
}
}
Then in another project (that is into the same solution) I have a class that contains a reference to the previous CpeManager class, something like it:
DataModel.CpeManager manager = new DataModel.CpeManager("DefaultConnection");
My problem is that Visual Studio give me the following error message on the previous line
The type or namespace name 'DataModel' could not be found (are you missing a using directive or assembly reference?)
What is the problem? How can I solve it?
Tnx
Andrea
You need to add a reference to the project which contains the Datamodel namespace. You do this by right clicking your project which requires it and selecting add reference, locate your project with DataModel in and add it in.
EDIT: As Tim noted you also need to make your CPEManager class public if you want to then be able to access it
Make CpeManager public.
public class CpeManager : MyManagerCSharp.ManagerDB
{
// ...
}
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using ProcessMemoryReaderLib;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
This seems to always return the error
"Error 1 The type or namespace name 'ProcessMemoryReaderLib' could not be found (are you missing a using directive or an assembly reference?) C:\Users\giacomo\documents\visual studio 2010\Projects\WindowsFormsApplication1\WindowsFormsApplication1\Form1.cs 10 7 WindowsFormsApplication1
"
In your Solution Explorer, right click your References > Add Reference then click Browse, then find and select your .dll File and add it to your references. You can't include a library in your project with using if you don't include your assembly.
Take a look at here for more details: http://msdn.microsoft.com/en-us/library/wkze6zky.aspx
Just build the project after adding the reference of the ProcessMemoryReaderLib.dll in your project,then use using ProcessMemoryReaderLib; in your class file
