Install-Package MySql.Data.Entity
installs version 6.9.8 by default. Your connector must match the actual version of the NuGet Package.
You can download an updated version of the connector from:
https://www.mysql.com/products/connector/
Here select the "Ado.net driver for MySQL", and download the corresponding version (in this case 6.9.8).
Reopen Visual Studio and now the wizard does not crash.
No reboot required.

This is for an ASP.NET MVC application, which does not have an app.config file.
I will not recount the failed attempts, but what worked for me was the following:-
With VS not running, download and install "MySQL for Visual Studio 2.0.5" - the latest version at time of writing.
Start VS2017 and uninstall the "MySql.Data.Entity" and "MySql.Data" NuGet packages, if
they have been previously installed in VS2017.
Download and install the latest MySql connector/NET using the links above (version 8.0.13 at time of writing).
In your project add references to the "MySql.Data.dll" and "MySql.Data.EntityFramework.dll" dlls as described above by Lopez93, but N.B. the "MySql.Data.Entity.EF6.dll" mentioned did not exist in 8.0.13, only "MySql.Data.EntityFramework.dll".
Now edit the web.config file and make sure that in the section, there is this line
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.EntityFramework">
Remove or comment out any other '<provider invariantName="MySql.Data.MySqlClient"...' lines.
Rebuild the project.
Try using the wizard again.
For me this worked.
Good luck!

Open MySQL Installer and install the latest version of Connector/NET
Uninstall / reinstall the latest version MySQL.Data.* packages with versions that match the version of the newly installed Connector/NET package
Restart Visual Studios
Rebuild solution
Taking suggestions about NuGet versioning from others answers.
I solved this issue by deleting the .Data
and Data.Entitiy.EF6
installed by Nuget.
Then right click on References and browse for:
C:\Program Files (x86)\MySQL\Connector.NET 6.9\Assemblies\v4.5\MySql.Data.dll
C:\Program Files (x86)\MySQL\Connector.NET 6.9\Assemblies\v4.5\MySql.Data.Entity.EF6.dll
I was then able to complete the ADO.Net wizard, with the .edmx models.
I know the solution.
Nuget installs edge version of MySql.Data.* packages, while you probably have previous version of the connector (In my case packages were v. 6.9.6 and Connector was 6.9.5). This comes to the point where you have version mismatch.
Be aware that if you use Install-Package MySql.Data.Entities in NuGet you will get even older version like 6.8.3, so you have to add the references by yourself and keep an eye on which one you are trying to add to your solution.

I ran into this issue upgrading from version 6 of MySql to version 8.0.17.0. I struggled with this for almost two days trying all of the old remedies until I came across this article.
If you are using EF6 and version 8.0.? of MySql, according to this post:
MySql.Data.Entity 6.10.7 isn't compatible with MySql.Data 8.0.11.
Oracle renamed the package to MySql.Data.EntityFramework for v8.x. You need to uninstall MySql.Data.Entity and install MySql.Data.EntityFramework.
Once I did this simple step, the data connection started working and the EDMX designer started working as well (although I have to go back to 2017 Visual Studio because the Designer Tools for VS 2019 were not available at the time of this post.)
Hope this newer post helps some of you.
I had the same problem using MySQL Connector 6.9.8.0. While all my versions matched, this still failed. I had installed a new version of Visual Studio AFTER the MySQL connector (From 2010 to 2013). For me, the solution was to uninstall the MySQL Connector for NET and then reinstall it (Exact same version). Then restart Visual Studio.
Seems like this is another version of the same problem.
Add a new empty EF model.
In the emdx design rigth click and update the model from database.
choose your database and the model will be generate.
That's work for me :)

--->install the entityframework 6.2.0 via nuget.
--->Verify in your web.config/app.config file that you have the System.Data.SqlServerCe.4.0
provider. if it's not installed, then install it via nuget, the exact same version as the entity framework previously installed (6.2.0 in this case).
--->then add the references: (in this case from the connector/NET version 6.9.10)
C:\Program Files (x86)\MySQL\Connector.NET 6.9\Assemblies\v4.5\MySql.Data.dll
and C:\Program Files (x86)\MySQL\Connector.NET 6.9\Assemblies\v4.5\MySql.Data.Entity.EF6.dll
and rebuild.
--->try adding this provider too:
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
rebuild, again.
--->and finally, try adding the .edmx file with a new connection.
This worked in my case where i installed VS2017 and MySQL in a brand new laptop, and had the same issue.
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.EntityFramework, Version=8.0.11.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6"></provider>

Step 3
Add codes (at the below) to web.config
<system.data>
<DbProviderFactories>
<remove invariant="MySql.Data.MySqlClient"></remove>
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.8.4.0, Culture=neutral" />
