…un by the integration tests.
On Linux, BIT64 is always defined (previous behavior). In the native profiler for Linux, get the path for the PInvoke by checking the platform-specific profiler path environment variable and falling back to the general environment variable if the first is undefined.
Tests are clean except for the Linux run of the |
Tests pass minus the Linux StackExchange SmokeTest 😄 |
Do you guys have any other feedback on this PR? The integration tests are passing so the Linux port is working correctly. |

The main mechanism for loading the managed profiler code was introduced in #462 (commit 4ce932f).
This PR turns on the feature for Linux. The main components are embedding the resources into the shared library, retrieving the embedded resources in the native profiler, and adding the correct PInvoke from the injected assembly load.
