Visual Studio 2010 Not Recognizing Unit Test

In an existing solution I added a new Test Project. In my Test Project .cs file I have a class decorated with the [TestClass] attribute and a method decorated with the [TestMethod] attribute. I have verified that in Configuration Manager the build check box is checked for the Test Project (as my google search has revealed was the problem for others with this issue). I have set Test Project as my start up project for the solution. When I try to start the test I get "Can not start test project because the project does not contain any tests". I am really new to unit testing. What am I missing?

[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
       Whole bunch of stuff
       Assert.Inconclusive("Done");
    }
 }

Update: So I opened a new instance of VS, went to File => New => Project => Test Project. Did not touch or edit anything. Went straight to the cs file and here are its contents in its entirety:

using Microsoft.VisualStudio.TestTools.UnitTesting;

namespace TestProject2
{
 public class Inspection
 {
    public bool SubmitInsp()
    {
        return true;
    }
 }

 [TestClass]
 public class UnitTest1
 {
    [TestMethod]
    public void TestMethod1()
    {
        Inspection insp = new Inspection();
        bool result = insp.SubmitInsp();

        Assert.IsTrue(result);
    }
 }
}

Same error about the project not containing any test when I try to start it. Also found this in the build output "Could not load file or assembly '~\my documents\visual studio 2010\Projects\TestProject2\bin\Debug\TestProject2.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)"

I don't know that units tests get much simpler than this. What the heck???

Verify that all the .cs files are marked as Compile in the Properties window. If it is marked as Content then you will hit this issue.

For me it was just that my class and method weren't public (I realize the poster did have public, but I found this post by Googling "testclass testmethod margin icons missing"). Dumb mistake on my part, but maybe it will help others.

The FrstCBC's anwser did not worked for me. I am on a VirtualBox machine with Windows 7 64 bits and Visual Studio 2012.

I had to move the output to a local folder : open the unit tests project properties and in the Build tab, browse the Output path to a local folder. The tests are now detected and can be run.

I was able to get this to work by modifying the devenv.exe configuration file found here:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config.

Add the following line to the <runtime> section, then restart Visual Studio:

<loadFromRemoteSources enabled = "true" />

(Here is the link that helped me)

I've had the same problem, when tests in an working test project suddenly weren't recognized anymore.

Comparing the project file with one from another working test project showed me that the <ProjectTypeGuids> node was missing from the main <PropertyGroup> node.

Adding this line inside the <PropertyGroup> node solved my problem:

C#: 

<ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>

VB:

<ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{F184B08F-C81C-45F6-A57F-5ABD9991F28F}</ProjectTypeGuids>

Test Projects saved to a network folder or anywhere locally on my computer have this issue. Created another Test Project and saved it to my flash drive, works just fine. I don't know if it is because my machine is 64 bit or because its a virtual machine or what, but I guess I just need to test everything on external storage devices.
