nunit TestContext throws NullReferenceException

I have the following code:

[TestFixture]
public class LexicalTests
{
    [Test]
    public void LexicalTest1()
    {
        TestContext.CurrentContext.TestDirectory;
    }
}

CurrentContext throws an exception while attempting to get TestDirectory or WorkingDirectory property.

How can I solve this problem?

P.S.: On my home PC tests work perfectly (without strange exceptions).

It seems that some applications that offer the functionality to run NUnit unit tests have a problem with the TestContext class.

The test in class below should pass:

using NUnit.Framework;

namespace UnitTests
{
    [TestFixture]
    public class UnitTests
    {
        [Test]
        public void CurrentContextTest()
        {
            Assert.IsNotNull(TestContext.CurrentContext);
            Assert.IsNotNull(TestContext.CurrentContext.TestDirectory);
            Assert.IsNotNull(TestContext.CurrentContext.WorkDirectory);
        }
    }
}

If the test doesn't pass then, as Dmitry wrote in his comment above, change the NUnit version in the ReSharper menu. From within Visual Studio, go to ReSharper -> Options -> Tools -> NUnit. Click the Specified NUnit installation radio button and ensure that a folder with nunit.core.dll, nunit.core.interfaces.dll and nunit.util.dll is specified. An error will be displayed if the listed files cannot be found.

Once the NUnit version has been changed, re-run the test and it should pass.
