Hey

 

Exception seems that it was sqlite and mdf file is used in Sql Server.

 

I think you might be using sqlite class for opening sql files.

 

Do check to resolve your issue. 

after deploye it is running on my pc. But when i try to run on somebody else`s PC it give me exception

above is directry  after instalation on my Pc

If you install your app to another pc, I´m quit sure there is NOT the same directory structure as on your development pc. If you 'install' your app with an installer your binaries will possibly be located somewhere in 'Program Files', not in YOUR Visual Studio Projects Directory.

And further, don´t try to locate your db in the directory where your bin´s are.

 

 

I had the same issue. To solve it I change the connection string datasource to the c: folder. So I had to put my database on the target computer.
