i am getting this exception while debugging my wp8 app on the device. System.ExecutionEngineException . Upon searching the net, i found suggestions to disable concurrent garbage collection and include that in app.config file. How can i do this on windows phone 8. I don't see that in my project. Where should i include this configuration.
<configuration>
<runtime>
<gcConcurrent enabled="false"/>
</runtime>
</configuration>
Kindly help on this.
That configuration should go an the app.config file. If your project doesn't have one, then you can add it.
I seriously doubt, though, that this will fix your problem.

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
I'm trying to put an ASP page on my website that accesses a MySql database. The Website project was built in VS2015 and I used MySql.Data dll version 8.0.11.0 (the latest release).
I hosted the website on localhost on the development machine with IIS server. The web.config file has the following assembly reference which was created by VS -
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="MySql.Data, Version=8.0.11.0, Culture=neutral, PublicKeyToken=C5687FC88969C44D"/>
</assemblies>
</compilation>
Everything works fine on the development machine, I can access the database, execute queries, etc.
The problem comes when I upload everything to the hosting server. The assembly reference above causes the following error from the parser -
Parser Error Message:
Could not load file or assembly 'MySql.Data, Version=8.0.11.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified.
I'm thinking that the host server may not have this latest version. Could this be the problem, and if so, how should I reference the MySql.Data assembly?
I have looked all over the web, but cannot find anything very specific, would greatly appreciate any help.
The proposed fix was to paste the MySQL.Data dll in bin folder
I downloaded and installed the NuGet Package: Select.Pdf. At runtime, when I click on the button that utilizes the code using the Select.Pdf namespace, I get the following exception:
The package is in the proper file directory and is properly installed, as you can see via the packages.config file:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Select.Pdf" version="16.4.0.1" targetFramework="net452" />
</packages>
I've been fighting with this for 2 weeks and I'm pretty much over it. Has anyone ever encountered this? Does anyone know how to fix this?
Possible fixes for this issue:
Please check whether Nuget package restore is enabled and the
packages are restored properly.
A folder called packages will be added to the folder where the solution file (.sln) exists when you build the solution or restore NuGet packages.
Please check the reference path to the assembly in your project file
and the actual location of the assembly is same.
If both project (.csproj) and solution(.sln) files are in the same folder then it will be packages/select.pdf in your project file
The version you are using in code and referencing can also cause the
mismatch.
Ensure the assembly version restored and referred in the project file are same.
I am developing a Windows Store App and I like to keep the most recent baseline installed while developing the next.
The problem is that whenever I run the current developmental version in Visual Studio 2013 (with F5) it un-installs the recent baseline.
I create and install a baseline by manually editing the Package.appxmanifest as follows:
edit the Identity Name
Append .R to every instance of the app name (eg. MyApp to MyApp.R)
(full file listing below)
I think that should be enough, but in my vain attempts to get this working I have also, in the project properties, append .R to the Assembly name, eg. MyApp.R, and changed one number in the MyApp_TemporaryKey.pfx
Then, when I run the app (F5) it is installed as MyApp.R, and persists and can be used outside Visual Studio.
The problem is that when I undo these changes to resume development, and run it again as MyApp then MyApp.R is uninstalled, and I am left with only the latest version, ie. MyApp.
I know that this is achievable because I have done it once before. I didn't record exactly what I did that time, because it didn't seem too hard, but after hours of trying I can't do it again. Either I haven't reproduced the steps correctly, or something has changed in Windows 8.1 since I last did it.
Why does Windows think the two versions are the same App? Is there another identity or key which I haven't changed?
Package.appxmanifest:

The Identify in the Manifest is the important part (in the visual manifest editor this is the "Package Name"). Changing the Identity is sufficient to allow both versions to be installed. You can also change the Identity to something meaningful rather than a GUID.
As you note, Visual Studio will uninstall the old version it has staged for you, but you can create a deployment package and install it again yourself.
When you are ready to switch to a new baseline use the Project.Store.Create App Packages... menu to create a development test package (i.e. not to upload to the store).
Update your manifest to use the new Identity. Changing the display names is not technically necessary but will make things less confusing.
Building this will install the new version and remove the staged version.
Now install the development package you created: go to AppPackages folder and run the Add-AppDevPackage.ps1 for the older version you want to reinstall.
You will end up with a normally deployed (in Program Files\WindowsApps) developer package of the old version and a staged (in your VS project directory) package of the new version.
(Alternatively, you can shuffle the versions to rename the old version to indicate it's old, create an app package for the renamed version, re-rename the Identity back to the original, and then install the dev-package for the old renamed version).
Try this if it works... Worked for me
Run the baseline application
Create a new working folder (or branch if you are using a code repository like TFS)
Eg : VS 2013 -> Projects -> App 1 then create VS 2013 -> Projects -> App 1-Copy
Change the Package Name in Package.appxmanifest under packaging tab in the new working copy
something which will be unique like changing the last couple of digits (to make a distinction between both the apps you can change the display name under Application tab and package display name under Packaging Tab)
and run the new application
this will list both your baseline and your development version
Hope this helps
I'm trying F# on OS X and I'm having trouble installing packages. My problem is to use MySQL.
I have downloaded Nuget and I can launch it. However, I didn't find any useful documentation about how to use it on the command line.
I managed to install MySQL.Data by doing
mono nuget.exe install MySql.Data
which downloaded it to my current repository. Is that normal? I was expecting it to be "installed" in a more central directory.
Moreover, when I try to require it, r "MySql.Data it doesn't work. It works if I set the include path properly by doing:
fsharpi --lib:MySql.Data.6.8.3/lib/net45
But that seems super heavy. Is there a way to add all the installed nuget in the path automatically?
Short answer: No.
Long answer: Yes, but it won't be what you hoped for.
It is possible to get NuGet to put installed library some specific place. On Mac OS, add the following to the end of ~/.config/NuGet/NuGet.Config
<configuration>
<config>
<add key="repositoryPath" value="/path/to/where/you/want/it/to/go" />
</config>
</configuration>
However, (a) NuGet still puts DLLs in different directories, so there is still no single place for fsharpi to find them. (b) Anyway fsharpi doesn't honor $MONO_PATH, Mono's canonical way to add to the DLL search path.
The closest I've come to a workable solution for fsharpi is:
Whenever you nuget a package, manually add it to MONO_PATH (say, in ~/.profile). E.g., supposing you told nuget to put stuff in /opt/nuget you would add:
export MONO_PATH=$MONO_PATH:/opt/nuget/MySql.Data.6.8.3/lib/net45
Whenever you run fsharpi, explicitly feed it $MONO_PATH:
fsharpi -I:$MONO_PATH
If you feel adventurous you could then patch the fsharpi script to automatically include $MONO_PATH.
I find that this is not worth the effort. Simply constructing a script that starts fsharpi with the options you need for whatever you're currently working on is a much more practical solution.
I'm an F# programmer on a Mac. My life is like an illicit love affair with someone married: I endure all the little slights because my heart leaves me no choice.
The most common use I see is
mono nuget.exe install mysql.data -OutputDirectory packages -ExcludeVersion
Which would install in your project's directory (generally you ignore the packages directory in your repository however and just restore it with a script) and you'd then find it at packages/MySql.Data/lib/net45
Downloading nuget to your repository is also common.
You can always write your own script to do the the fsharpi hookups you want, nuget has a lot of convention, so it's possible to pick the right dll from lib/*/ for your purposes
And it's possible to do it with an fsharp script, here's an fsx script that can be executed directly, it downloads nuget, installs from nuget, and then executes another script (with fake not fsharpi, but that's totally possible.
