@shethaadit, thanks for the contribution!
Looks like we can delete some of the model classes from KernelBuilderExtensionsTests as well, since they are not in use anymore. See the failing dotnet-format job

Hi @westey-m, Thank you for your comments. I have updated it.

@shethaadit, you probably saw there was an error during the CI build. The reason for this error is that the change we are making here is a breaking change. We have checks in place to avoid making breaking changes accidentally. Since we are deliberately making a breaking change here though, we can update a suppression file to work around it.

To do so, just run the following command from the dotnet folder of this repo:
dotnet build --configuration Release /p:GenerateCompatibilitySuppressionFile=true

This will update the required suppression files. Push the updates to those files, and the build should then pass.

Thanks again for helping out!

dotnet build --configuration Release /p:GenerateCompatibilitySuppressionFile=true

Hi @westey-m, Thank you for your guidance, I tried that but build still fails.
