title: Nunit - doesn't discover tests [no error-message]
body: <p>Unit refuses to dsicover or run my tests in an assembly. This is not the case where Unit produces an error message like "Unable to find test in assembly". It simply doesn't discover that I have tests.</p>
  
  <p>I right-click the test-method and the test output shows: </p>
  
  <p>Discover test started ------
  Discover test finished: 0 found (0:00:00,0260026)"</p>
  
  <p>I have tried everything mentioned in this post: 
  <a href="https://stackoverflow.com/questions/618292/nunit-doesnt-find-tests-in-assembly">NUnit doesn&#39;t find tests in assembly</a></p>
  
  <p>Upgrading is not a possiblity. The processor architecture settings are correct. My tests are public and have all the correct tags. </p>
  
  <p>Here's some code from my project that I simply can't get to even execute. I know that because I have a break-point right at the beginning. </p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using NUnit.Framework;
  
  namespace UnitTestProjects
  {
      [TestFixture]
      public class SomeRandomTests
      {
          [Test]
          public void ShouldFail()
          {
              Assert.AreEqual(1, 0);
          }
  
          [Test]
          public void ShouldPass()
          {
              Assert.AreEqual(1,1);
          }
      }
  }
  </code></pre>
  
  <p>I'm running the internal visual studio test explorer. Unit Framework version 2.5.9.10348, runtime version v2.0.50727. I have Unit Test Adopter installed. I've attempted reinstalling it with no success. </p>
