Can't import classes from same namespace

I'm fairly new to .NET and I'm trying to get an old program to work that no longer has it's .csproj file. I've managed to receive an old .sln file from the creator and opened the solution in VS.
From what I can see this is a Developer Web Server project?
Here is the issue.
In the folder Smreka there are 2 files, log.cs and smreka.cs. The log.cs contains the implementation of a class Logger, which I am trying to import in to smreka.cs. They are both using the same namespace Bum.Iglavci.Smreka so as far as I know, I should be able to import the Logger class without any issues.
The problem is that the compiler just can't see it. If I try to directly import it with using static Bum.Iglavci.Smreka.Logger;, I get an error Feature 'using static' is not available in C# 5. Please use language version 6 or greater.
I would like to know why the namespace can't see each other. Is it because I'm missing the .csproj file? Does Developer Web Server even need a .csproj file? If so what's the best way to generate one?
EDIT:
Due to some confusion I'll try to add more details regarding how log.cs and smreka.cs look like. The files are actually a lot longer but I think this should give an idea.
log.cs:
namespace Bum.Iglavci.Smreka{
public class Logger{
public Logger(){
}
public void DoSomething(){}
}
}
smreka.cs:
namespace Bum.Iglavci.Smreka{
public class Baza{
private Logger log;
public Baza(){
log = new Logger();
}
}
}
The compiler has no idea what Logger is under property private Logger log; It states the error The type or namespace name 'Logger' could not be found (are you missing a using directive or an assembly reference?)
I think the namespace is correctly placed, that's why i have a feeling there's something wrong with the project or the solution itself that i need to fix.

Since both classes are in the same namespace they are already able to use each other. You can acces the class by simply doing the following. Let's take Log as the class to call the other class.
Log class:
namespace Bum.Iglavci
{
public class Log
{
public static void ExecuteDoSomething()
{
Smreka.DoSomething();
}
}
}
Smerka class:
namespace Bum.Iglavci
{
public class Smerka
{
public static void DoSomething()
{
//execute code here
}
}
}

It could be possible that the files have the Buil Action property set to
None this will not compile the files. Set it to C# Compiler, this should solve it.
If you don't know how to acces the properties of a file.
Right click the file
Navigate to Properties in the bottom of the list
Set the Build Action to C# compiler (see image)

I found no simple solution. I now created a new .net framework application project and added the files in to the new project. For some reason the namespace works correctly now and the files can see each other in the same namespace.

Yes the error comes from the fact that you don't have a .csproj file.
Such files contain the list of files to compile when building a project. Just having the solution file is not enough.
I suggest some readings on project and solution using Visual Studio :

Class Library Localization in Windows Universal / Store App

I have a solution with a Windows Store app project and a Class Library project and I want to add Localization support.
How can I add the all the Resource files to my Class Library and use them in both my App and Class Library?

In order to avoid writing a lot of boilerplate and error prone code when you add a new resource string like:
Add it to .resw file
Add it to your Static class that provides access to the resource
Add it to each language specific .resw file (ex: en, fr, pt, etc)
You can use the following approach:
Create "Strings" folder and add there just one folder for default language (for example "en-US") in your Class Library
Add Resources.resw file to "en-US" folder with required keys/values
Install Multilingual App Toolkit
Enable MAT in VS for your Class Library (VS->Tools->Enable Multilingual App Toolkit)
Add required languages to your Class Library (VS->Project->Add Translation languages...)
Install ResW File Code Generator VS extension
Go to Resources.resw file properties and set Custom Tool to "ReswFileCodeGenerator" (you can also specify namespace in Custom Tool Namespace)
To solve issue with supported languages detection(currently generated manifest contains supported languages according to folder structure "Strings/en-US") you need to add folders for all required languages in your App library ("fr-FR", "bg-BG", etc) and put Resources.resw file with only one fake key.
Build your solution and enjoy!
With this approach all your resources are available via static class generated by ReswFileCodeGenerator and all of them work with x:uid in XAML. You don't need to care about keys synchronization between different languages. Also MAT can translate your resources for you.

Ok, I found how to do this and with a sample project found here
Basically the implementation is the following:
In the ClassLibrary create a folder named "Strings"
Inside the Strings folder create one for each language (ex: en, fr, pt, etc)
And add a Resources.resw in each of those folders with your keys/values
Now add a new Class in your ClassLibrary that has the following code(adapted to your project):
using System;
using Windows.ApplicationModel.Resources;
namespace MyClassLibraryName.Tools {
public static class LocalizationTool {
static ResourceLoader resourceLoader = null;
public static string MyStringOne {
get {
String name;
GetLibraryName("MyStringOne", out name);
return name;
}
}
private static void GetLibraryName(string resourceName, out string resourceValue) {
if(resourceLoader == null) {
resourceLoader = ResourceLoader.GetForCurrentView("MyClassLibraryName/Resources");
}
resourceValue = resourceLoader.GetString(resourceName);
}
}
}
And in your ClassLibrary or MainApp just call the following:
string text = LocalizationTool.MyStringOne;

project with localisation folder and classes?

I'm trying to use a new resources file with localisation in a Silverlight Project from 2009.
I've added a new resource file to the folder Resources in my Silverlight Application and if
I try to use the new resources in a control (.xaml) I get the blue underlining with the message "could not resolve resTest.resx).
I found a folder "Localisation" with classes like this:
namespace SilverlightApplication.Localization{
public class ContentGrid
{
public ContentGrid() {
}
private static Resources.ContentGrid _Resource = new SilverlightApplication.Resources.ContentGrid();
public Resources.ContentGrid Resource
{
get
{
return _Resource;
}
}
}
}
I've added a new class for my new resources file, but it doesn't work. Still the same error. I only know the automatic resources method, where I put a resource file in the folder Resources and everything works automatic.
Maybe I'm doing something wrong?

I read the flowing article which explains how to make xaml content localizable.
http://msdn.microsoft.com/en-us/library/dd882554%28v=vs.95%29.aspx
I forgot to make an entry in the app.xaml file.

Could not find any resources appropriate for the specified culture or the neutral culture

I have created an assembly and later renamed it.
Then I started getting runtime errors when calling:
toolsMenuName = resourceManager.GetString(resourceName);
The resourceName variable is "enTools" at runtime.
Could not find any resources
appropriate for the specified culture
or the neutral culture. Make sure
"Jfc.TFSAddIn.CommandBar.resources"
was correctly embedded or linked into
assembly "Jfc.TFSAddIn" at compile
time, or that all the satellite
assemblies required are loadable and
fully signed.
The code:
string resourceName;
ResourceManager resourceManager = new ResourceManager("Jfc.TFSAddIn.CommandBar", Assembly.GetExecutingAssembly());
CultureInfo cultureInfo = new CultureInfo(_applicationObject.LocaleID);
if(cultureInfo.TwoLetterISOLanguageName == "zh")
{
CultureInfo parentCultureInfo = cultureInfo.Parent;
resourceName = String.Concat(parentCultureInfo.Name, "Tools");
}
else
{
resourceName = String.Concat(cultureInfo.TwoLetterISOLanguageName, "Tools");
}
toolsMenuName = resourceManager.GetString(resourceName); // EXCEPTION IS HERE
I can see the file CommandBar.resx included in the project, I can open it and can see the "enTools" string there. It seems that either resources are not included into assembly or resource are included but .NET cannot resolve the name.

I think simpler solution would be to create separate resources file for each language.
As far as this case is concerned check if the assembly containing resources has the default namespace set to the same text (Project->Properties->Default namespace; in VS)
Check as well if the resx file has a property BuildAction set to "Embedded resource"

Sounds similar to an issue we had. The namespace was incorrect in the resource file's designer. I fixed it by manually re-running the custom-tool on the resx file.
Right click your.resx, and click Run Custom Tool.

I'm sure you've already got the answer, but just in case:
You can view your ManifestResourceName by calling
System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames()
Check that Manifest name and your name in GetString() calling are identical.
Also, be sure you have correct namespace in designer.resx file:
namespace Jfc.TFSAddIn {
...
global::System.Resources.ResourceManager temp =
new global::System.Resources.ResourceManager(
"Jfc.TFSAddIn.CommandBar", typeof(CommandBar).Assembly);
...
}
Open resx file properties: "Build Action" should be "Embedded Resource"

For me, the source of the problem was naming the rex files starting with a number:
20160216_tranlation.resx
I had to add an underscore _ before the resx file name when calling GetGlobalResourceObject:
public static string getResource(string key)
{
return HttpContext.GetGlobalResourceObject("_20160216_tranlation", key).ToString();
}

I corrected the namespace in designer file (Resources.Designer.cs) in ResourceManager static property & it worked for me.
See the code below:
[global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Advanced)]
internal static global::System.Resources.ResourceManager ResourceManager {
get {
if (object.ReferenceEquals(resourceMan, null)) {
global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("XYZAssembly.Properties.Resources", typeof(Resources).Assembly);
resourceMan = temp;
}
return resourceMan;
}
}

I added a temporary class within my Form.cs while (testing || debugging) that caused this exception to be thrown. The Form.resx file (Name || Resource ID) was modified to the temporary class name instead of the Form class name. This caused the issue for me. I (corrected || alleviated) this by creating a separate file for my temporary class in the project.

One Solution is to change the property of resx file from content to Embedded Resource and Build it.Sure this time u vil get

I have encountered this issue in Xamarin.Forms, when I tried to the rename the project, the resources could not be loaded anymore with the same stated error text.
To fix the problem I had to modify the .csproj by a text editor, and change the logical name of the embedded resource.
<EmbeddedResource Include="Localization\TextResources.resx">
<Generator>ResXFileCodeGenerator</Generator>
<LastGenOutput>TextResources.Designer.cs</LastGenOutput>
<LogicalName>YourNewNamespaceName.TextResources.resources</LogicalName>
<SubType>Designer</SubType>
</EmbeddedResource>
Also watch out for the autogenerated class when you rebuild it, the namespace stated in there might change.
Hope it helps someone that went into the same situation.

Got this error when I added a class ABOVE the partial form class in my Windows forms app.
It went away when I moved the class BELOW the partial form class.

This answer solved the problem for me! GetGlobalResourceObject

.Net Reflector not properly linking resources

Ive decompiled a library but when i try to run it, anything that requests something from the resource manager doesnt work properly leaving me with "{"Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"Logistics.Products.LayerPicking.Properties.Resources.resources\" was correctly embedded or linked into assembly \"LayerPicking.PBG\" at compile time, or that all the satellite assemblies required are loadable and fully signed."}"
[EditorBrowsable(EditorBrowsableState.Advanced)]
internal static System.Resources.ResourceManager ResourceManager
{
get
{
if (resourceMan== null)
{
System.Resources.ResourceManager manager = new System.Resources.ResourceManager("Logistics.Products.LayerPicking.Properties.Resources", typeof(Resources).Assembly);
resourceMan = manager;
}
return resourceMan;
}
}

It looks like the decompiling changed the name. The Resource looks like it is LayerPicking.PBG.KUKARoboter.Logistics.Products.LayerPicking.Properties.Resources - notice the "LayerPicking.PBG." - which is the name of your project.
VS.Net likes to add the default namespace of the project to the beginning of the resources when it embeds them.
So here are 2 options (you can do either one - I would recommend #1):
Change your default namespace to KUKARoboter and rename your resx files to start with Logistics (not KUKARoboter).
Search for the "KUKARoboter.Logistics string and add in your default namespace to the string so it reads like the string it is looking for "LayerPicking.PBG.KUKARoboter.Logistics"
