System.IO.File.ReadAllText call "breaks" code coverage #331

Description

Calling System.IO.File.ReadAllText inside a test class "breaks" code coverage.

Steps to recreate

  1. Create an NUnit test project (or Class Library).
  2. Create a test.
  3. In the middle of the test add something like "string fileContent = System.IO.File.ReadAllText(pathToAnyFile);".
  4. Run all tests.
  5. Fine Code Coverage shows everything above the line as covered and everything after that line as uncovered (including any classes that are being tested).

Current behavior

Fine Code Coverage stops tracking covered code after encountering a System.IO.File.ReadAllText call.

Expected behavior

System.IO.File.ReadAllText calls shouldn't be affecting the code coverage.

What I expect is happening is that the test is failing when executed by FCC. ReadAllText is throwing an exception. The reason is mentioned on the readme page. If you switch to ms code coverage there will be no issues.
