LTTngDataExtensions unable to process traces from NET6.0+ project #102

Closed tomithychen closed 1 year ago

tomithychen commented 1 year ago

During trace processing, an exception is thrown (shown below) when processing an LTTng trace when run from a NET6.0 or NET7.0 project. When used from netcoreapp3.1 and NET5.0, the trace processing still works.

You can repro this by modifying the LTTng unit tests within the repo to target those versions of .NET

Repro

  1. Change LTTngDataExtUnitTest/LTTngDataExtUnitTest.csproj targetframeworks to build NET5.0, NET6.0, and NET7.0 a. <TargetFramework>netcoreapp3.1</TargetFramework> -> <TargetFrameworks>netcoreapp3.1;net5.0;net6.0;net7.0</TargetFrameworks>
  2. Rebuild LTTngDataExtUnitTest (will probably have to re-open solution first)
  3. Run all LTTngDataExtUnitTest tests in each framework
  4. netcoreapp3.1 and net5.0 tests all pass
  5. net6.0 and net7.0 unit tests all fail to process traces (although 3 of the unit tests still pass in each)
