MySql Connector/Net is not working properly. The team working on bugs is only 3 people and they do not resolve complex issues. There are still unresolved issues from 2009. I want to customize their connector so that it works for my complex situation. How can I use a customized version in my project instead of theirs?
Step 1) Download
In order to customize a version of oracle's mysql connector / net you are going to have to download the source code here: http://dev.mysql.com/downloads/connector/net/
Step 2) Open
Next, you are going to have to unzip the downloaded source files. The meat of the connector will be in two of the projects, MySql.Data and MySql.Data.Entity ( What is in a mysql provider? ).
Step 3) Edit The Connector
Make any edits to the classes you wish in order to fix your complex situation.
Step 4) Remove the signature
This step will make redistributing your edits undesirable, you may sign it and make the changes if you wish but for a local deployment it is unnecessary.
Inside of MySql.Data.Entity's AssemblyInfo.cs comment out this line:
//[assembly: AssemblyKeyName("ConnectorNet")]
Inside of MySql.Data's AssemblyInfo.cs make these changes:
//[assembly: AssemblyKeyName("ConnectorNet")]
[assembly: InternalsVisibleTo("MySql.Data.Entity")]
Step 5) Compile and Build In Order
Build MySql.Data first. Once built, open MySql.Data.Entity. There will be a warning about not being able to find MySql.Data. Add the reference to the newly built MySql.Data inside of the bin/Debug folder. Build MySql.Data.Entity as Release.
Step 6) Move the files
Inside of the bin/Release folder of MySql.Data.Entity should be both MySql.Data and MySql.Data.Entity. Take each one and overwrite their counterparts in your project's package folder.
Step 7) Update References in your project
Inside of your project, go to the references area. Remove both MySql.Data and MySql.Data.Entity. Right click on References, click Add Reference, select the Browse tab, navigate to the package folder, and then add both MySql.Data and MySql.Data.Entity that you placed there in Step 6.
Step 8) Modify web.config
There will be several mentions of MySql.Data inside of web.config. Each one of them will have PublicKeyToken=c5687fc88969c44d which must be removed (from all of them).
Step 9) Make it so
Enjoy your customized connector!
There is now a community-developed open-source .NET connection library for MySQL: https://github.com/mysql-net/MySqlConnector.
It provides true async I/O (for high scalability) and fixes many bugs in Oracle's Connector/NET.

This issue has been reported on GitHub here -
https://github.com/TorbenK/TK.CustomMap/issues/325
Has anyone else has struggled with this? I was stoked to find this nuget package because it does exactly what I'm looking for but it needs Places and some other GooglePlayServices installed and I can't install them because of this conflict.
I'm also not sure if uninstalling TK.CustomMap and then installing the Play Services would even help because the person who reported the issue on GitHub said-
I converted my app to .net 2.0 and had to use the newest Google play services
60.1142.1 for AdMob to work. It wouldn't install until I uninstalled TK.CustomMap, and now TK.CustomMap won't reinstall because it only want to use GooglePlayServices 42.1021.1
Severity Code Description Project File Line Suppression State
Error NU1107 Version conflict detected for Xamarin.GooglePlayServices.Tasks. Reference the package directly from the project to resolve this issue.
HunterTracker.Android -> Xamarin.GooglePlayServices.Base 60.1142.1 -> Xamarin.GooglePlayServices.Tasks (= 60.1142.1)
HunterTracker.Android -> HunterTracker -> TK.CustomMap 2.0.1 -> Xamarin.GooglePlayServices.Location 42.1021.1 -> Xamarin.GooglePlayServices.Tasks (= 42.1021.1).
That's pretty much the exact error I'm getting trying to install the other packages. There's no resolution on github.
Anybody found a work around? Or does anyone know how to "Reference the package directly from the project"?
Thanks to SushiHangover's comments above pointing me in the right direction I was able to discover what I needed to do here. I had an error updating the nuget packages of TK.CustomMap at first because v26 Xamarin.Android.Support.Vector.Drawable was targeting MonoAndroid8.0 and the update to v27 must target MonoAndroid8.1 So it took quite a bit just to be able to update the nuget packages in order to get the assemblies with later versions so I could use TK.CustomMap in my solution. But I was eventually able to get there. Here were the steps I followed (as best I can remember). I am unable to compile ios right now because I don't have a MAC so that fix will have to come later. This fix is for the shared project and Android project only
Download the TK.CustomMap-master from github
Extract it and delete the Sample project completely (I also deleted the UWP project as I'm not really interested in that at this time)
Opened and built then closed. Deleted packages folder, vs folder, bin and obj from Android and Shared Project (this step is probably not necessary but I did it so...)
In the packages.config in Android changed all targets from monoandroid80 to monoandroid81 save file
In the TK.CustomMap.Android.csproj for every v26.0.1 of any Xamarin.Android.Support or other Xamarin.Android util package changed 26.0.1\lib\MonoAndroid80 to 27.0.2.1\lib\MonoAndroid81 - save file
In the nuget folder in TK.CustomMap.nuspec changed the target framework in this section
<group targetFramework="lib\MonoAndroid7.0">
<dependency id="Xamarin.GooglePlayServices.Location" version="42.1021.1" />
<dependency id="Xamarin.GooglePlayServices.Places" version="42.1021.1" />
<dependency id="Xamarin.Android.Maps.Utils" version="0.5.0" />
<dependency id="Xamarin.Forms" version="2.5.0.91635" />
<dependency id="Newtonsoft.Json" version="10.0.3" />
</group>
to
<group targetFramework="lib\MonoAndroid">
so it could target any version
Opened and updated all nuget packages using package manager (not console). Built debug and release builds
At this point opened solution I had tried to implement TK.CustomMap in previously to attempt the fix. Remember the original issues was that the latest frameworks could not be used and 42.1021.1 frameworks were unable to locate com.google.gms.location and com.google.gms.places.ui files so they had to be updated or no TK.CustomMap
In the problem solution uninstalled TK.CustomMap from all projects
In the problem solution Android project added reference to all the dlls in the release folder of the Android bin file from TK.CustomMap project.
Installed updates for all Xamarin.Android frameworks in problem solution through Package Manager (not console)
Installed updates of all other nuget packages for all projects using Package Manager (not console)
Installed TK.CustomMap to Shared project using Package Manager (not console)
Added the References to the android project a second time. May or may not have helped.
Installed TK.CustomMap Nuget Package using Package Manager (not console)
Built and ran on Live Player successfully!!
Thanks to Sushi Hangover for the advice. I haven't seen any comprehensive tutorials anywhere on how to accomplish this so I figured I would post my own answer in case anyone else was looking. Definitely if you are new to VS all this stuff is no walk in the park in the beginning.
Thanks to #Travis Fleenor. This is my solution. I change a bit your sequence in order to work on mine.
1. Make sure the original proyect from github (https://github.com/TorbenK/TK.CustomMap) works and you can run it.
2. Update the nugets where you get the conflict. In my case I got conflicted in googleplay library version. I updated it in the original proyect and then assure it could run it.
3. Compile entire solution in release mode. Then, copied the generated dll from bin/release and pasted them in a folder in my desktop.
4. I referenced those dll to shared proyect and android proyect. I only used nuget package manager to install some missing packages needed for the tk.custom. Notice that you only will reference some dll that the proyect accept. For the mayority Visual will prompt ' dll already referenced' something.
5. first reference your shared proyect, later your android one. That's all. make sure the you ca recompile solution.
Hope this helps
In fact, I wanted MySql.Data.Entity.EF6, however, for some reason Visual Studio ADO EDMX editor wanted MySql.Data.Entity.EF5 (same version, 6.9.9.0).
First, I checked if the NuGet packages 'MySql.Data' and 'MySql.Data.Entity' were installed.
I then issued the following command in PowerShell to reinstall all packages to help fix any .net version errors:
update-packages -reinstall
and proceeded to verify that all references in web.config were correct; however, the error remained. I even reinstalled MySQL for Visual Studio 1.2.6, but still the same.
(FYI: Restarting Visual Studio at each step above)
The solution for me was to simply add a new "dummy" ADO Entities Data Model to the project, referencing the same database (not sure this matters), which seemed to correct some references (somewhere) within the solution/project to the wrong version of the MySQL DLL (the error said 'EF5', but it should have been looking for 'EF6'). I'm sure there was a cache somewhere that was doing this, but just not sure where.
Edit: In retrospect, I perhaps should have tried deleting the obj folder first, as there are some *AssemblyReferences*.cache files in there. I tried rolling back to a previous version of the source (using Git) to test this, but the old version works now! So I'm sure it must have been the obj folder, which is ignored by Git by default.
I have made a program in Visual Basic which connects to my MySQL server, asks for the password and checks it to the username...
Not very secure, as i learned how to use a database yesterday(i had never touched it before...).
Now, when i try to compile to an exe, gets it from the release folder, and puts the release folder on my other PC, it is missing the MySQL.Data, which i had to add as referance in visual basic...
Is there any way I can include dependencies in my Exe/Release? This will of course apply to all dependencies!
BTW, i am using Visual Basic 2010 Express!
After adding reference, go to Solution Explorer window, expand References, click on MySql.Data to select. Go to Properties window and set Copy local property to True. After next build, you will get missing MySQL.Data.Dll in build folder. Then you can copy .exe and .dll to other PC.
I'm trying to use the sqlite-winrt library at https://sqlwinrt.codeplex.com (cf. http://blogs.windows.com/windows_phone/b/wpdev/archive/2013/05/30/sqlite-winrt-wrapper-for-windows-phone.aspx) because I need to access an SQLite database via SQL commands in a WinRT 8.1 and a WP8 app and this library seems the only available option.
Anyway, there is no binary release and if I try compiling the source I get several link errors for unresolved externals against the SQLite DLL. I posted an issue at codeplex but got no reply yet, so I was wondering if anyone had already managed to successfully compile this lib and how (or if you know of any viable alternative for RT8.1 and WP8). Here is what I did:
downloaded the latest source from the site.
downloaded and installed 2 VSIX from http://www.sqlite.org/download.html: sqlite-winrt81-3080002.vsix for RT 8.1 and sqlite-wp80-winrt-3080100.vsix for WP.
executed the powershell scripts in each subfolder of the source code solution, which are required to update the projects with newer releases of the SQLite for WinRT extension. The current versions of the scripts refer to SQLite for WinRT 8.1 (prerelease) which is the same I downloaded above.
opened the VS2013 solution and removed the RT project (I just need RT8.1 and WP, this was for WinRT 8.0).
5) built the solution, which failed with link errors.
If I see the RT8.1 project properties, I can confirm the reference to SQLite is under C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs\SQLite.WinRT81\3.8.0.2.
Did anyone manage to use this lib? Thanks!
I also once had that problem. I fix it by editing the project file manually. At that time, the powershell script updating the wrong path. That's why I always failed when compiling my project. After I edit the project file using external text editor (I use sublime text), the projects are linked correctly.
You can try DatabasesCx. It is another SQLite Wrapper using Windows Runtime Component technology. It is freeware distributed as precompiled binary. You can find the details at http://www.almanacsoft.com/databasescx
I have a solution that is primarily developed in Visual Studio 2012. I would like to develop in MonoDevelop without major incompatibilities.
Thus far, I have installed mrward's nuget addin for MonoDevelop and things work if I manually add each package in packages.config through that interface. However, this is highly onerous. This addin doesn't have support for automated package restore as of this writing.
I downloaded nuget.exe from CodePlex ("NuGet command line utility", as it's labeled). I use a simple find/xargs combination to install all required packages:
find . -name packages.config | xargs -I '{}' mono nuget.exe install '{}'
This creates several dozen directories in the directory from which it is run instead of putting things under packages/ as expected, and it also doesn't touch the project files so MonoDevelop still thinks that it should be looking for package references in the directory from which MonoDevelop was started.
I therefore opened MonoDevelop from the working directory that contains all of these package folders, and I still get invalid references. I think this is probably because the project is looking for package_name/ reference, but the folders are name package_name.version/ in the working directory.
Any suggestions for a sane, simple way to interact with this solution? I'm next going to try modifying my shell command so that it automatically drops to project/packages and runs nuget from that directory.
Did you try using the -o command line parameter with NuGet.exe? You can use that to get the packages to install into a particular packages folder.
The NuGet addin for MonoDevelop supports package restore from version 0.6 or above. Right click your project and select Restore Packages. This will download all the packages defined in your packages.config for all projects in the solution. It uses NuGet.exe to do this.
Another way to get this working is to use the custom NuGet MSBuild target so the package restore happens at build time when using xbuild. It would require some manual editing of project files though. Under the covers the custom MSBuild target just uses NuGet.exe with a similar command line to what you have already just with the output directory option specified. So I would try the command line approach since that will be less work.
You would have to get the following files from the NuGet repository on codeplex:
NuGet.exe
NuGet.targets
NuGet.config
Put these in a directory somewhere. Typically these are put in a .nuget directory in the same directory as your solution file. Then you need to edit your project files to include the NuGet.targets file and also define the SolutionDir property. So something like this:
<SolutionDir Condition="$(SolutionDir) == '' Or $(SolutionDir) == '*Undefined*'">..\..\</SolutionDir>
<Import Project="$(SolutionDir)\.nuget\NuGet.targets" />
You will also need to enable package restore on your machine. You can do this using the NuGet addin for MonoDevelop in the Options dialog. Under Linux this is available from the Edit menu under Preferences. Then look in the NuGet - General options and there is a checkbox for enabling package restore.
There is an example project on GitHub created by Jonathan Channon which uses package restore and works when building with xbuild inside MonoDevelop. There is also an issue on GitHub about using NuGet restore on Linux which might be helpful.
Update: 2014-05-14: NuGet addin for MonoDevelop now supports package restore.
