Answer 1

I experienced similar problem; install oracle data access components (odac ODTwithODAC122010.zip) for solution.

Answer 2

Looks like you did not install the Oracle Instant client (or any other version of Oracle Client). This is a prerequisite for unmanaged ODP.NET provider.

Install the Oracle Instant client and you are fine. Otherwise you will get nothing but trouble.

Answer 3

I managed to make it work.

• Download the good version of the ODAC that will target your project.

  1. For a 32bit project you need to download the ODAC12..._x32.zip (ODAC121021Xcopy_32bit.zip).

  2. For the 64bit project you need to download the ODAC12..._x64.zip

• Unzip it in an empty folder depending on the version you want (32bit vs 64bit).

• Locate in the instantclient_12_1 folder all the dlls by searching *.dll in the windows search bar. You need to grab:

1. oci.dll

2. ociw32.dll

3. orannzsbb12.dll

4. oraociei12.dll

5. oraons.dll

• Locate in the odp.net4 or odp.net20 folder depending on your .NET version this two dlls:

1. OraOps12.dll

2. Oracle.DataAccess.dll

• Copy the those 32bit dlls or 64bit dlls and put them directly in the Output path of your project. For example in C:\...\vsProjects\BulkInsert\BulkInsert\bin\Debug.

• Browse Oracle.DataAccess.dll in your project by pointing on the Output path.
