Can not generate entity data model

Question

Hi!
I try to generate enitity data model based on db tables...
The first wizard's window asks me to choose the model content - I choose "Generate from database". After this, wizard disapears and there is no .edmx file in solution explorer.
However, when i choose "Empty model", wizard works properly and generates empty .edmx file.
Who knows what is wrong?
Thanks

 Hi,

does it not even ask you to specify or create a new connection to your database?
when you choose to generate a model from a database?

Probably, yes. (I do not remember). But I can not find it in the list of installed programs. On another PC everything works fine :(

Hi, can you list all the "post" installs which you installed after installing visual studio with the latest service pack?

Hi -

I'm not exactly sure what is happening here, but one of the problems we've experienced in the past is that you have a persisted data connection on your machine, and that data connection requires either a DDEX provider or an ado.net provider to be successfully opened. 

Try opening VS, opening server explorer, and then deleting any database connections you have in server explorer.  Then try running the EF wizard. 

Let me know if this works.

Hi,
Thanks to everyone! Sorry, for not replying immediately...
Now, everything is fine. What I have done is that I reinstalled all stuff (VS, SQL Server, framewrok, SP1 and etc..). This helped, however I stil do not know what was wrong :(

Thanks
