EF DbContext generator doesn't work. "overwrite the replacement token '$edmxInputFile$'"

[sorokinDev]

Problem:

EF DbContext Generator doesn't work in Visual Studio. Just today's morning everything worked fine, but later I noice following problem.

Error:

Running transformation: Please overwrite the replacement token '$edmxInputFile$' with the actual name of the .edmx file you would like to generate from.

Steps to reproduce:

Create New project. Click on EF DbContext Generator(5 or 6 version doesn't matter). It doesn't show selector with options "from database, code first..." as always. Instead it just generates 2 files: "Model1.Context.tt" and "Model1.tt" and shows the error above.

Screens:

Also:

I noticed in "Model1.Context.tt", that it has link and it returns 404.

private const string ExternalTypeNameAttributeName = @"http://schemas.microsoft.com/ado/2006/04/codegeneration:ExternalTypeName";

Further technical details:

I tried this on 3 PC: two with VS2017 and one with VS2015, all win10 x64.

This issue tracker is for EF Core, not EF6 - and I suggest you use the EF Reverse POCO template instead.

@sorokinDev As Erik says, this is the issue tracker for EF Core. For EF6, issues should be filed on https://github.com/aspnet/EntityFramework6. However, if we are going to be able to follow up on an issue there, then it will need to include full version information for Visual Studio (including which updates are installed.
