Create new .net core MVC project, run it, stop debug, then write in Package Manager Console the string to add migration:

It was working before update of VS 2019. Now I have 16.1.3. Generated files are inside in G:\testef\TestEf2\bin\Debug\netcoreapp2.2 folder.

  1. dotnet tool uninstall --global dotnet-ef
  2. dotnet tool install --global dotnet-ef
  3. dotnet ef
  4. dotnet ef migrations --project YourProject.Data --startup-project YourProject.UI add InitialCreate
  5. dotnet ef database --project YourProject.Data --startup-project YourProject.UI update

It worked for me. I can create migration and db.

### Error solution The error appears when programming in Microsoft.AspNetCore.MVC with NET 5.0, when trying to create a Migration and a DataBase. By typing in the package manager console:

PM> Add-Migration InitialCreate (or Update-Database) Build started. Build succeeded. The specified deps.json [C: \ VSProjects \ RazorPagesMovie \ RazorPagesMovie.deps.json] does not exist, and the migration is not created and then not all the tables in the DataBase are created.

Solution:

  1. In appsettings.json, in "DefaultConnection" remove the final part "MultipleActiveResultSets = true"
  2. In the package manager console (PowerShell), and having installed "Dotnet": a) dotnet tool uninstall --global dotnet-ef (To Remove it only if it exists) b) dotnet tool install --global dotnet-ef (To Install it if it does not exist) c) dotnet ef (To see that it is installed correctly) d) dotnet ef migrations add InitialCreate e) dotnet ef database update

In View -> SQL Object Explorer, you will find the DataBase with its tables.

I have the latest one Version 16.1.5 and still I am getting the same error.

running Get-Project 'Project_Name').ConfigurationManager.ActiveConfiguration.Properties.Item('OutputPath').Value, throwing error from Package Manager console. You cannot call a method on a null-valued expression. At line:1 char:1

  • (Get-Project 'CoreWebTest').ConfigurationManager.ActiveConfiguration ...
  • + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull

same error: The specified deps.json [C:\Users\xxxxx\source\repos\EFCoreTest01\EFCoreTest01.deps.json] does not exist

and null value error when I try: Get-Project 'Project_Name').ConfigurationManager.ActiveConfiguration.Properties.Item('OutputPath').Value

Using: Windows 10 Pro and Visual Studio Community 16.9.3

Same exact issue here.

bricelam commented 3 years ago

Can you create a new issue? That looks like something new specific to Blazor web assembly projects...

bhojim commented 3 years ago

I had similar issue. I closed Visual Studio. Then I re-opened the solution. Tried again. It worked.

Kanderson124 commented 3 years ago

I had the same issue in Azure Devops and was driving me crazy because i was using the release pipelines to deploy my changes. Basically after following the above directions for making sure entity framework is installed globally, i noticed that the code HAS to be built in order for that deps.json file to be generated which is in the bin folder and also most importantly it was in the bin debug folder for me, which means debug configuration. On azure devops the default configuration is release...

In View -> SQL Object Explorer, you will find the DataBase with its tables.

I think that this is more an alternative but not a solution, i mean actually you are using dotnet CLI and the error is specific of package manager console.

What i want to use is Add-Migration from PMC, not "dotnet ef migrations add InitialCreate".

The error is still there, im using visual studio 16.9.4 and getting the same error in a new and clean project pmcerror

aguerrieri82 commented 3 years ago

Same here, solved today

I was thinking about some mess in VS project system manager assemblies and VS SDK's (maybe the Package Manager Console was loading the wrong assembly version and it wasn't unable to parse the "new" cproj project type). In my case I was right The issue started when I've installed and old version of VS (2008 in this case). Nor reinstall VS 2019 or repair it did work, but UNINSTALLING the old visual studio solved the problem for me

I hope it can help somebody

  1. dotnet tool uninstall --global dotnet-ef
  2. dotnet tool install --global dotnet-ef
  3. dotnet ef (This is only to check that "DOTNET EF" is installed correctly.)
  4. dotnet ef migrations --project YourProject.Data --startup-project YourProject.UI add InitialCreate
  5. dotnet ef database --project YourProject.Data --startup-project YourProject.UI update

This worked, but only after I changed directory into the subdirectory of the project with dbcontext and specified the full project name, including the .csproj file name extension.

psp650 commented 3 years ago

Encountered this issue in VS 2019 community edition running dotnet ef dbcontext scaffold.

Tried most of the suggestions here without success.

Despite building successfully before running it, what ended up working was to remove the --no-build option from the command. After removing that it started working.
