    I experience the same issue.
    I think that using the Visual Studio plugin instead. works most of the time.
    I think that only the SSMS plugin has this problem, on my machine at least.

    Hi both,

    So sorry for this issue, it seems to be related to the new filter option on the Generate Migrations page.

    We are looking into this and will post here once we have an update. In the meantime, however, you can likely get around this by installing this version which doesn't have the filtering feature:
