Exception message: "Constructor on type 'System.Data.Entity.Migrations.Utilities.DomainDispatcher' not 
found."
CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : MissingMethodException

my command in Package manager Console is: EntityFramework\Add-Migration -StartUpProjectName "xxx" myMigrationName

The problem at least on my machine is that version 3.0.0.0 of the System.Management.Automation assembly is loaded in the package management console, and EntityFramework.PowerShell.Utility.dll is build against version 1.0.0.0.

I have a temporary fix of adding the following binding redirect to “C:\Users\USERNAME\AppData\Local\Microsoft\VisualStudio\15.0_313c23f6\devenv.exe.config”

<dependentAssembly>
    <assemblyIdentity name="System.Management.Automation" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
    <publisherPolicy apply="no" />
</dependentAssembly>

Note, the fix needs to be applied everytime you update VS.

I was able to figure this out as its the same issue as this one https://github.com/PowerShell/PowerShell/issues/6189

Which i was also having, but was fixed in a recent VS update. Hopefully the fix they applied is easy for you too!

It was reported in https://twitter.com/tore_aurstad/status/1115005326011641856?s=21 that this issue also repros on Visual Studio 2019.
