Having installed managed ODP.NET on my computer, the ODP.NET Managed Driver does not appear inside the Choose Data Source dialog in Visual Studio 2013 Professional.
This is how it should look like:
This is how it actually looks on my machine:
I've followed the steps described in the "An Easy Drive to .NET" article on the Oracle website.
I've also installed the Oracle Developer Tools for Visual Studio. Still no managed driver to select.
My question:
Is there anything I forgot to do in order to make the data provider appear?
The generic answer to this question is "(Re)install 'Oracle Developer Tools for Visual Studio' (ODT)". Simply getting ODP.NET from Nuget or from other sources is not enough to take advantage of Visual Studio integration. You must install ODT also.
Download "ODTwithODAC":

Update 4/2018: If you are using Visual Studio 2017 Community edition, please upgrade to version 12.2.0.1.1 or later. That is the first version that works with VS 2017 CE: http://www.oracle.com/technetwork/topics/dotnet/downloads/odacmsidownloadvs2017-3806459.html
As you noticed, sometimes installations get munged. So if you do not see the driver in the dialogs or are getting generic (non-oracle ORA-) errors when you try to use features then you should reinstall ODT.
Open your Registry editor and check if RegKey HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\odp.net.managed exists. It contains only the (Default) value with location of your Oracle.ManagedDataAccess.dll.
Add the key in case it is missing, example:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\odp.net.managed]
#="c:\\oracle\\product\\12.1\\odp.net\\managed\\common"
You can also try the Oracle config scripts at {ORACLE HOME}\odp.net\managed\x64\configure.bat and {ORACLE HOME}\odp.net\managed\x86\configure.bat, they should do the same
Then check your compile options whether you selected target Framework at least to .NET Framework 4.
Update for Release 12.2
Key odp.net.managed seems to be used in old version 12.1. Latest release uses Oracle.ManagedDataAccess:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\Oracle.ManagedDataAccess]
#="C:\\oracle\\product\\12.2\\Client_x64\\odp.net\\managed\\common"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\Oracle.ManagedDataAccess.EntityFramework6]
#="C:\\oracle\\product\\12.2\\Client_x64\\odp.net\\managed\\common\\EF6"
While Wernfried posted his answer I tried at the same time the following approach:
Uninstall any previously installed Oracle packages/drivers.
Restart Visual Studio.
After these steps, the drivers were present:
I'm still not 100% sure, why a simple uninstall fixes something.
Old post but same issue. THe root cause is - i think - if you have VS 2022 installed the ODT for VS 2017 or 2019 does not install properly. I had to uninstall all versions of VS, reinstall VS 2017, reinstall ODTwithODAC183. Ensure that it can actually find the latest version of VS 2017 - I used the Visual Studio installer and it installed the latest version of VS 2017 Pro. I think that made a difference too. It looks like otherwise the installer won't find VS 2017 properly (if 2022 is installed) and the whole thing is fubar.
To test if it's installed correctly, add a entity data model and you should be able to see the oracle option in the data source list.
I has same error. Since I installed vs2015 Update 3.
solve
Reinstall Oracle Developer Tools for Visual Studio 2015.

I have installed Oracle Developer Tools for Visual Studio 2017. I am now finally able to create my database classes within VS2017 without switching back to VS2015.
After the installation I am getting the following error message upon opening an old project and also when creating a new Oracle database connection (in a new project) in Visual Studio 2017:
oracle data provider for .net has been installed without a
machine-wide configuration
(...) Also found anoher version in the GAC that might be incompatible, please uninstall it and restart VS2017
(Poorly translated the german message to english, but you get the point)
Problem is: The version in my GAC is the newer version needed for VS2017. I definitly do not want to uninstall that, but the non machine wide data provider from earlier. I can't find anything about how to do that. Do you guys have any ideas?
Please forgive me if my attempt itself is not smart at all => I haven't installed Oracle Tools for VS before and ran into loads of problems doing so earlier.
Just for the record: I have been trying to google for a solution, but I did not manage to find one. If you got the key-Keywords let me know-
I installed this Version from 6th july 2017
Oracle Developer Tools for Visual Studio 2017 (12.2.0.1.0)
This download includes:
Oracle Developer Tools for Visual Studio 12.2.0.1.0 Oracle Data
Provider for .NET 4, Managed Driver 12.2.0.1.0 Oracle Providers for
ASP.NET 4 12.2.0.1.0
I did a lot of installing of the Oracle tools before getting it to work. Not an expert, but I found many installations of my "Oracle Home". In order to uninstall versions that I did not want, I used the Oracle Universal Installer. This is found (for Windows 7) in "Start Menu -> All Programs -> Oracle-Ora Client-your specific client -> Oracle Installation Products.
Run the installer and choose which oracle home you want to uninstall. You should be able to determine which one is the one that you want to uninstall by looking at Registry Keys, HKLM->Software->Oracle. Also HKLM->SOFTWARE->Wow6432Node->ORACLE. There may be others, search for Oracle keys.
SO figure out which oracle home you want to uninstall and use the Universal Installer to remove it. This should preserve the installation that you want and remove the one you don't. I'm not an expert, just offering what has worked for me.
In Visual Studio 2017, when I create new connection (using the wizard), there is a hard-coded path to a TNSNAMES.ORA file, that can't be changed through the wizard. It is set up through the above-mentioned registry keys. This is key to mapping your Data Source to an actual database. Hope this is helpful.
Trying to run an old project in Visual Studio 2015. It was created in 2012 or 2013, I cannot remember which. I have uninstalled both programs as I was running out of space, and i think that is what caused this. I get the following options:
And I do not want to change the target, so clicking on the second option brings me to https://www.microsoft.com/net/targeting which I can't seem to find anything there that remedies the situation. Is there a way around this without reinstalling the old version of Visual Studio again? Will that even fix my problem? Thank you.
Just Reinstall Visual Studio. When you uninstalled previous version it caused this problem.
You could try doing a repair reinstall of Visual Studio 2015.
Another point to consider is that Windows 7 (the oldest version of Windows still supported by Microsoft) includes a Windows Update for the .NET Framework v4.6.1 categorized as an "Important" update. I have not confirmed with Windows 8, but I suspect it, too, includes a similar update. Windows 10 comes with .NET 4.6 to start with. That means that any up-to-date supported machine today will be able to run apps targeting any .NET version up to and including 4.6. I recognize that there may be other reasons to continue targeting an older .NET version, but I bring this up just in case the concern is support on client workstations.
Though this is not programming specific problem, I hope this is also the right place to ask this.
I'm having problems using Firebird DB with Visual Studio.
I had previously installed FirebirdClient v4.2.0.0 and DDEX v3.0.1.0, but in my project I used newest version of client and there was a mismatch between the two when adding new ADO.net models (connection in Databases window was working perfectly fine).
So I uninstalled the v4.2 and installed newest version (4.6.2.0), but now when I try to add new connection:
Visual Studio 2013 Pro crashes after entering one letter into any of the textboxes:
I tried:
relaunching VS
reinstalling both FirebirdClient v.4.6.2 and DDEX v.3.0.1
but nothing seems to help. Anything I missed I can do to make this work?
I had also downloaded some NuGet packages, but since I even tried this with closed solution I don't suppose this is project-related issue.
Some further notes:
I've read about GAC and the need of adding the assemblies into it, but as far as I understand, in the newest versions of Firebird .Net Provider it is done automatically
My specs:
Win 8.1 Pro
VS Pro 2013
Firebird 2.5.2
FB .Net Provider 4.6.2
DDEX 3.0.1
I had the same Problem and the solution was to uninstall the DDEX 3.0.1 and FB.Net Provider. Remove all Firebird entries from the machine.config provider section. Reinstall both and it should work again, the uninstaller of the Provider doesn't remove this entries so Visual Studio crashes.
The machine config is located under:
32-bit
%windir%\Microsoft.NET\Framework[version]\config\machine.config
64-bit
%windir%\Microsoft.NET\Framework64[version]\config\machine.config
Downloaded and ran SQLite setup.
Added dll reference to my project
In Server Explorer, added new connection, clicked 'Change' for data source and SQLite was one of the options.
Connected and used my tables.
Then...VS 2010 crashed.
When I reloaded my project, my connection wasn't in Server explorer, so tried to add it again.
SQLite was not in the list of options.
Re-ran SQLite setup, deleted/re-added reference, restarted project...still no SQLite in the list.
How can I get SQLite connected in Server Explorer???
This is an old question but for someone, like me, who finds this before there is a newer answer:
missing SQLite data provider in VS 2013
Basically for the latest versions of SQLite you can download an installer that includes the components
http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
Choose the right setup for you, for me was:
Setups for 32-bit Windows (.NET Framework 4.5.1)
sqlite-netFx451-setup-bundle-x86-2013-1.0.94.0.exe
I have Windows 7 x64 with Visual Studio community 2015 and this solution worked for me.
Basically you need install SQLite bundel and check the "Install the designer component for Visual Studio 2015".
If you have different version from 2015 (2010/2013 etc.) just search for the bundle the suits your version.
1. Go to:
http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
2. Download "sqlite-netFx46-setup-bundle-x86-2015-1.0.104.0" (download the most updated, this is the one I found).
Or by a direct link:
http://system.data.sqlite.org/downloads/1.0.104.0/sqlite-netFx46-setup-bundle-x86-2015-1.0.104.0.exe
3. Run the setup:
4. Result:
You can find installers on the System.Data.SQLite Dowload Page. Seteps files will suit your needs.
For example, the description of the Setups for 64-bit Windows (.NET Framework 4.0) states:
This setup package features the mixed-mode assembly and will install all the necessary runtime components and dependencies for the x64 version of the System.Data.SQLite 1.0.81.0 (3.7.12.1) package. The Visual C++ 2010 SP1 runtime for x64 is included. The .NET Framework 4.0 is required.
None of answers worked for me. in addition to #E235 answer
i added sqlite nuget package
updated ef to 6.1.3
then it worked i was able to see datasource
Opening VS2010 today, the extension manager notified me of an update for NuGet Package Manager.
During the install, I get an 'Installation Failed' with an option to view the log.
The key error message I see in that log file is:
The signature on the update version of 'NuGet Package Manager' does not match
the signature on the installed version. Therefore, Extension Manager cannot
install the update.
The version numbers I am upgrading from/to are as follows.
Current Version: 1.5.20902.9026
New Version: 1.6.21205.9031
I have also tried to install it while VS2010 is closed via this page:
here
Update: The recently released NuGet 2.0 also may require uninstalling an older version of NuGet first.
From the NuGet 2.0 Release Notes: (http://docs.nuget.org/docs/release-notes/nuget-2.0)
Known Installation Issue
If you are running VS 2010 SP1, you might run into an installation error when attempting to upgrade NuGet if you have an older version installed.
The workaround is to simply uninstall NuGet and then install it from the VS Extension Gallery. See http://support.microsoft.com/kb/2581019 for more information, or to go directly to the VS hotfix.
Note: If Visual Studio won't allow you to uninstall the extension (the Uninstall button is disabled), then you likely need to restart Visual Studio using "Run as Administrator."
Here is the VisualStudio/Express hotfix for this issue...
http://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=38654
There's not much on the page describing what it's for, but it's linked to from here that does provide some description...
http://connect.microsoft.com/VisualStudio/Downloads
I have installed this hotfix on both the Professional (on Win 7 Pro 32 bit) and Express versions (on Windows 7 Ultimate 64 bit) and the NuGet update behaves as it should.
When i originally had the problem, Joe Doyle's answer solved it.
However, going to version 1.8, I cannot see a listing for nuget in Programs and Features.
So from within Visual Studio / Tools / Extension Manager.
Uninstalled NUGET.
Restarted VS
Return to the Extension manager and install NUGET.
After uninstalling Nuget from Control panel, Go to C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet Package Manager\ or the location matching similar pattern based upon windows bit version, and delete the folder 1.0.11220.104. And, if you install it now, you wont' get the same problem.
