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

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.
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":
http://www.oracle.com/technetwork/topics/dotnet/utilsoft-086879.html
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.

I'm using VS 2013 to develop Win 8.1 app. I chose to deal with SQLite but I coudn't find the data provider when I was trying to add a new connection to manage my database.
Any help is appreciated
Install this:
http://system.data.sqlite.org/downloads/1.0.101.0/sqlite-netFx46-setup-bundle-x86-2015-1.0.101.0.exe
and reboot evertything
I have lost 3 hours with this problem
Updated with new version.
Updated with sanuel-jackson's comment info.
http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
and download Setups for 32-bit Windows (.NET Framework 4.5.1) where
This is the only setup package that is capable of installing the design-time components for Visual Studio 2013.
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
I just installed visual studio 2010 but when i create a new project Framework 4 does not appear in the options for target framework. I know framework 4 installed correctly because the new app pools set to v4 were created in IIS. For some reason it's just not showing up in visual studio. I tried repairing dotnet 4 and reinstalling visual studio but still no luck. Anyone else have this problem or know how to fix it?
First of all you shoul use the .NET Framework Setup Verification Tool to check the .NET 4 have been properly installed.
I also recommend you to check the both products language, sometimes it could be the problem.
If everything is ok, i guess you have registry problem, so you would have to check the installation keys or use .NET uninstall tools.
More info:
Detection keys for .NET Framework 4.0 and Visual Studio 2010
Uninstall .NET Framework Tool
Visual Studio does not detect .NET Framework 4
Hope helps!
I had the same problem and it turned out to be that I needed the Microsoft .NET Framework 4 Multi-Targeting Pack. No other combination of actions would fix this.
I tried all the ways but no success,
According to this link,you can solve this problem by copy frameworklist.xml file from another computer and paste it in your system.
I had the same problem and I resolved it. I found out that there were no file FrameworkList.xml in folder C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\RedistList.
But I noticed this file in machine where .Net Framework 4 is accessible from VS
2010. Then I copied this file to my computer and restarted VS 2010. And .Net Framework 4
appeared from drop down list.
I attached frameworklist.xml file from my system :Download frameworklist.xml
Changes which lead to missing .Net4 problem:
1.
I changed some registry settings in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
CommonFilesDir
CommonFilesDir (x86)
CommonW6432Dir
ProgramFilesDir
ProgramFilesDir (x86)
ProgramW6432Dir
All those were moved from C: drive to another drive (E: in my case)
2.
I changed the location of some user folders:
C:\Users\<name>\AppData\LocalLow
C:\Users\<name>\AppData\Roaming
Those were moved (via Properties->Path->"Move" button) from C: drive to F: drive.
After reverting 1. back to drive C:
and creating symbolic links in C:\Users\<name>\AppData to the new locations,
it worked again (note: I uninstalled VS before reverting the changes, and installed again afterwards)
(Create link with: mklink /d C:\Users\<name>\AppData\LocalLow E:\Data\LocalLow)
I can not say if both changes are really needed, because I changed both at once.
But finally it works again ;)

I'm seeing the same problem. We were using my build box to test installs of a WinForms app on a machine without 4.0. We bundled 4.0 in the manifest and the app works, Framework 4 Client Profile and Framework 4 Extended show up in add/remove programs, but there is still no 4.0 Framework in the VS2010 options.
BTW, reloading SP1 was no help.
I finally got this working by running the VS2010 setup in repair mode. I now see Framework 4.0 options in VS2010.
That was a long and tedious process and now I have to patch to SP1 again. MSFT should fix this behavior in a SP soon.
Had the same problem. Numerous uninstalls and reinstalls of visual studio 2010 and the .NET 4.X frameworks didn't fix it.
Manually uninstalling the "Microsoft Visual Studio Macro Tools" item and then doing a repair install of VS2010 seems to have done the trick.
I had the same problem this week and it got resolved by installing Visual Studio 2012 RC.
Removing and reinstalling .NET Framework 4 didn't help and I couldn't reinstall Visual Studio 2010. After installing the 2012 RC the Framework 4
I had installed .NET 4.5, which ended up breaking something, so decided to uninstall. VS 2010 could not longer see .NET 4.0. I tried using the .NET cleanup tool and reinstalling, but no go.
Eventually what worked was what is posted at http://social.msdn.microsoft.com/Forums/eu/netfxsetup/thread/3dede142-82ce-430c-bbe6-d824f0fb94a4. I installed Windows Phone Developer Tools (http://www.microsoft.com/en-us/download/details.aspx?id=13890) up until the multi-targeting package, at which point I canceled installation.
You can reinstall the targeting pack using this command, this solved my issue:
Microsoft .NET Framework 4 Multi-Targeting PAck
WCU\MTPack
COMMAND--> NetFx_DTP.msi EXTUI=1 /log "%TEMP%\dd_netfx_dtp.txt"
I think it's because you installed higher version of .net framework, such as .net framework 4.6, Which caused the mistake of missing .net framework 4.0.
For me using Arash's fix worked "there were no file FrameworkList.xml in folder C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\RedistList".
I noticed I had other .NET versions and just copied the FrameworkList.xml from one of those to 4.0 RedistList folder and it worked.
Problem:
VS2010 ->Right Click on Project -> Property Pages - > Build->Target Framework
is showing up to .NET 3.5 only. I have installed up to .NET 4.5 framework.
Solution:
I tried many solutions and decided to take a drastic step to format. The following way I got the solution without formating o/s.
Removed all .NET installations
Installed one by one from 1.0 to 4.6 with sps available.
VS2010 setup with repair option selected.
Opened vs2010 project and .NET framework up to 4.0.3 found in the list.
