Project for Reproduction of RDLC Designer Hang/Crash

This project facilitates reproduction of a hang-then-crash bug in Microsoft RDLC Report Designer for Visual Studio. To reproduce:

1. Open RdlcDesignerAddDatasetCrash.sln in Microsoft Visual Studio Community 2019 version 16.11.7 with RDLC Report Designer version 15.3.1.
2. Run Update-Package -reinstall in the Package Manger Console. Important: Restore is insufficient. Must reinstall to repopulate bin directory.
3. Open Report.rdlc.
4. Right-click on Datasets in the Report Data window, then click Add Dataset....

At this point Visual Studio will freeze for about 50 seconds then restart.

I suspect that this is due to the presence of an .xsd file which is not a Typed Dataset in the App_Data directory.
