azuredatastudio: Database Projects extension: Build error on Linux (reproing on WSL)

Issue Type: Bug

1. Install .Net Core SDK: apt install dotnet-sdk-3.1
2. Configure /usr/bin as location for .Net Core SDK: "sqlDatabaseProjects.netCoreSDKLocation": "/usr/bin"
3. Create new database project: Ctrl + Shift + P, “proj new” (Database Projects: New Database Project)
4. Build the project: In “Projects” pane, right-click on .sqlproj file, select “Build”

Error:

stdout: /xxx/test/obj/Debug/test.dll : Build error SQL72025: The referenced assembly /XXX/TEST/OBJ/DEBUG/TEST.DLL is corrupt or not valid. [/xxx/test/test.sqlproj]

Fails on Ubuntu 18.04. Works on macOS.
