Hi Sachin,\

For solving above problem you should go the below link in your local computer

## \

```
\Windows\Microsoft.net\Framework\v****\machine.config
```

**\**

And add in the section of <system.data>.

\

```
<system.data>    <DbProviderFactories> <add name="Odbc Data Provider" invariant="System.Data.Odbc"/>     <add name="OleDb Data Provider" invariant="System.Data.OleDb"/>     <add name="OracleClient Data Provider" invariant="System.Data” />     <add name="SqlClient Data Provider" invariant="System.Data” />     <add name="IBM DB2 for i .NET Provider" invariant="IBM.Data/”>     <add name="Microsoft SQL Server Compact Data Provider"/>         </DbProviderFactories></system.data>
```

After that remove <DbProviderFactories/> empty tag.

\

Or , you can also solve the issue by nuGet

Go to Tools > Library Package Manager > Manage NuGet Packages For Solution

In the dialog, search for "EntityFramework.SqlServerCompact". You'll find a package

with the description "Allows [SQL](https://www.mindstick.com/articles/13115/types-of-keys-in-sql-or-oracle-database) [Server](https://www.mindstick.com/articles/43769/what-is-serverless-architecture-is-it-worth-switching-over) Compact 4.0 to be used with Entity

Framework." Install this package.
