Types already exist!!!! WHY???

Hope that someone will answer to me.

That's my problem, I've done my first program using Visual Studio 2003 (C#) and now I ported it to VS 2k5 but I receive this errors:

Error 1 The type 'Microsoft.DirectX.Direct3D.Device' exists in both 'c:\WINDOWS\assembly\GAC\Microsoft.DirectX.Direct3 D\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.D irect3D.dll' and 'c:\WINDOWS\assembly\GAC_32\Microsoft.DirectX\2.0. 0.0__31bf3856ad364e35\Microsoft.DirectX.dll' I:\clock_src\MovNumber.cs 24

Error 2 The type 'Microsoft.DirectX.Direct3D.VertexBuffer' exists in both 'c:\WINDOWS\assembly\GAC\Microsoft.DirectX.Direct3 D\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.D irect3D.dll' and 'c:\WINDOWS\assembly\GAC_32\Microsoft.DirectX\2.0. 0.0__31bf3856ad364e35\Microsoft.DirectX.dll' I:\clock_src\MovNumber.cs 26

Error 3 The type 'Microsoft.DirectX.Direct3D.Texture' exists in both 'c:\WINDOWS\assembly\GAC\Microsoft.DirectX.Direct3 D\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.D irect3D.dll' and 'c:\WINDOWS\assembly\GAC_32\Microsoft.DirectX\2.0. 0.0__31bf3856ad364e35\Microsoft.DirectX.dll' I:\clock_src\MovNumber.cs 28

I believe the solution is to install an older DirectX version.

Oh my god again??
I'm migrating from an old one to a new one then again to an old one :(
I'll try!

For the ppl that had, have, will have this problem, don't worry here the fix:

1) Look into .csproj
2) Search for <ItemGroup>
3) And modify these lines:

Code:

---

    <Reference Include="Microsoft.DirectX">
      <Name>Microsoft.DirectX</Name>
      <HintPath>C:\WINDOWS\Microsoft.NET\Managed DirectX\v9.00.1126\Microsoft.DirectX.dll</HintPath>
      <AssemblyFolderKey>hklm\current managed directx 9.1</AssemblyFolderKey>
    </Reference>
    <Reference Include="Microsoft.DirectX.Direct3D">
      <Name>Microsoft.DirectX.Direct3D</Name>
      <HintPath>C:\WINDOWS\Microsoft.NET\Managed DirectX\v9.00.1126\Microsoft.DirectX.Direct3D.dll</HintPath>
      <AssemblyFolderKey>hklm\current managed directx 9.1</AssemblyFolderKey>
    </Reference>
    <Reference Include="Microsoft.DirectX.Direct3DX">
      <Name>Microsoft.DirectX.Direct3DX</Name>
      <HintPath>C:\WINDOWS\Microsoft.NET\Managed DirectX\v9.00.1126\Microsoft.DirectX.Direct3DX.dll</HintPath>
      <AssemblyFolderKey>hklm\current managed directx 9.1</AssemblyFolderKey>
    </Reference>

---

as these:

Code:

---

    <Reference Include="Microsoft.DirectX, Version=1.0.2902.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <Reference Include="Microsoft.DirectX.Direct3D, Version=1.0.2902.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <Reference Include="Microsoft.DirectX.Direct3DX, Version=1.0.2902.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
