Entity Data Model Wizard crashes on Specify connection string dialog - entity-framework

Question

Whenever I try to add an entity data model in Visual Studio 2013 on Windows 8.1 I see the following.
Does anybody have an idea how to fix this? I see the dialog to specify a database connection appear for a split second then dissapears.

Answer 1

I found a solution. Go into view->Server Explorer and remove any "Data Connections". Then this worked again.

Answer 2

I solved it by doing the following.
Make sure the versions of MySql.Data, MySql.Data.Entities, MySql.Web dll files in C:\Program Files (x86)\MySQL\MySQL Connector Net x.x.x\Assemblies\v4.5 and C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies are the same.
Make sure your project references the same version of dll
In my case my
MySql connector was 6.9.6
C:\Program Files (x86)\MySQL\MySQL Connector Net x.x.x\Assemblies\v4.5 and C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies had it as 6.8.3
Project referenced 6.8.3.
After updating all versions with same dlls, now I am able to update the "Model from database"
Hope this helps someone
Edit: A few weeks after there was some windows update which again screwed up the settings. To resolve it, I had to re-run the My Sql Connector installation and My Sql for Visual Studio, it worked fine after that.

Answer 3

Delete all connections in the Database Explorer Window and in the ADO .Net wizard add a new connection. I was able to solve this problem this way.

Answer 4

you have to delete all other connection from server explorer and delete other connection ss web.config

Answer 5

I Had a similar problem, spent 2 days trying many solutions but I finally solved. I just had to :
- Install MySQL For Visual Studio 2.0.5
- uninstall and install MySQL Connector 6.9.9
Note: Please follow the order VS => Connector and respect the version.
Finally I faced other problem and solved by adding an empty emdx first then changing SSL Generate Template property from SSDLToSQL To SSDLTOMySQL

Answer 6

Install MySql for VS 1.2.9
Install MySql Connector 6.8.3
Add these Nuget Packages to your Project:
EntityFramework // 6.4
Mysql.Data // 6.8.8
Mysql.Data.Entities // 6.8.3
Mysql.Web // 6.8.8
In the Solution Explorer, edit App.config(Add or Replace):
<entityFramework>
<defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6" />
<providers>
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
</providers>
</entityFramework>
rebuild and nothing more

Answer 7

For Anyone having this issue in VS 2019. This is what I did after a week long troubleshooting and googling, I just remove:
EntityFramework
MySql.Data.Framework or MySql.Data (or any other MySQL Nugget Packages you have added)
Then I re-install just this two in same order:
EntityFramework
MySQL.Data.EntityFramework
Then Update you entityframework section in app.config/web.config as follows:
I did not add default connection factory, I also remove version info from MySQL
