Connect Firebird Database with Entity Framework model - Connection Failed

I want to connect the Firebird database with Entity Framework Model. Completed the successful installation and created the database. But, I am facing the issue 'Index was outside the bounds of the array' while connecting the database. Refer the below image.

• Visual Studio 2015
• Firebird client version 4.10.0.0
• DDEX Provider version 3.0.2.0
• Firebird setup v3.0.4

I followed the steps as suggested in this link. But I choose 'Embedded Server' as server type. https://firebirdsql.org/file/documentation/reference_manuals/fbdevgd-en/html/fbdg30-efw-vs-prepare.html

After done the above configurations, I faced the below.

Unable to load dll 'fbembed': The specified module could not be found. (Exception from HRESULT:0x8007007E)

So, I set 'fbclient.dll' as a client library in the advanced option. After that I am facing this error

Index was outside the bounds of the array

What I have done wrong here? Please correct me.
