Jeff,

Sorry for the delay.

1.Can you use Biml to create SSRS reports?

Not at present and I understand it is not currently on the roadmap

2.What version of .NET is BimlScript using?

3.5

3.Can you kick off package generation from Biml through PowerShell?

Yes and this is a Mist only feature.

4.Can you convert an existing SSIS package into Biml? (or do I need Mist to be able to do that?)

Yes and again this is a Mist only feature.

5.What are the capabilities of Mist over just using SSDT?

Here are a couple items: Analysis Services support (Mist 4.0 will now support Tabular), Transformers, Build Automation, SSIS Package Import, Full IntelliSense.

Hope this helps.

Reeves
