Prerequisites

1. Make sure that you have Visual Studio .NET 2005 Standard or higher edition.
2. Express editions are not supported.

Registry update

1. Remember to update the path in FirebirdDDEXProviderPackageLess32.reg or FirebirdDDEXProviderPackageLess64.reg, places where to update it are marked %Path%.
2. Install the .reg file into the registry.

Machine.config update

Add the following two sections to machine.config (located usually at C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config and C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\CONFIG\machine.config on 64-bit system).

<configuration>
  ...
  <configSections>
    ...
    <section name="firebirdsql.data.firebirdclient" type="System.Data.Common.DbProviderConfigurationHandler, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    ...
  </configSections>
  ...
  <system.data>
    <DbProviderFactories>
      ...
      <add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".Net Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=%Version%, Culture=%Culture%, PublicKeyToken=%PublicKeyToken%" />
      ...
    </DbProviderFactories>
  </system.data>
  ...
</configuration> 

And subst:

%Version% With the version of the provider assembly that you have in the GAC.
%Culture% With the culture of the provider assembly that you have in the GAC.
%PublicKeyToken% With the PublicKeyToken of the provider assembly that you have in the GAC.

Answer 1

Did you add a reference to the assembly in your project? If not, right click in the solution explorer on references and choose add reference. Find the Firebird client assembly and add it.
