@marcpopMSFT Looks like [InlineData("netcoreapp9.1")] is not a valid target framework version. Our test aims to ensure that the target framework version is higher than the current net10.0. However, netcoreapp9.1 is actually lower than net10.0, so it does not meet the test conditions. To ensure the validity of the test, we should use target framework versions higher than net10.0, such as netcoreapp10.1 or higher. What do you think?

@v-wuzhai the test already has netcoreapp10.1 which should be higher. Do we need anything else? If not, maybe we don't need this at all unless it's to test both a minor version higher in 10.1 and a major version higher in 11.0
