I have some code in fastcheck() in a v2 extension, but it seems it’s not being invoked by the VS Code v2 extension simulation? Can someone confirm?

It doesn’t, the fastcheck can be run via **dt-sdk run --fastcheck**

The VScode addon doesn’t add the **--fastcheck** since that would quickly exit the simulation after running the fast check
