System.IO.Compression Reference issue

I am working on .NET framework 4.6 Web API application. My app is working on my machine and I was able to build it in my local but when I push it to our Azure Dev OPS CI, I got this build error.
Error CS0433: The type 'ZipArchive' exists in both 'System.IO.Compression, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' and 'System.IO.Compression, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

Task Scheduler Fails .Net 4.5 Console Application

I have a .Net 4.5 Console Application written in C# that makes a call to SQL using Entity Framework 6.1.3 and generates a PDF. The application runs fine if you run the executable but it fails when ran through Task Scheduler. It will only run on Task Scheduler with option "Run only when user is logged in" I need it to run when not logged in.
What I did to test the executable in Task Scheduler was to mock the data gets called from Entity Framework and the application worked just fine so something tells me that Task Scheduler did not like my Entity Framework call. Yet I have other Schedule Tasks Running using Entity Framework.. Not sure what the problem is. Below is one the error seen in Windows Log.

I am using SQL Authentication. I added a try catch error and I get this:
Login failed: The login is from an untrusted domain and cannot be used
with Windows Authentication.
After looking at my connection string, I realized that I had copied the connectionstring from my PC to the server and replaced the data source but not the credentials....So its resolved.

App closing as soon as it loads, with no errors

One of my applications runs fine on my developing machine, although if I run it on another computer the app closes as soon as it loads.
I remember I got this problem one time when I didn't deploy the app.config, but I made sure it was deployed this time.
Since the application gives absolutely no errors and all the results from Google are misguided, I have no idea what to do.
What could be causing this behavior? Even though app.config is deployed I think it may be something about it or something about one or more references, but I'm not sure.

Apparently there was a call stack on the event logs

MySql.Data in GAC, still SecurityException

I have a problem with MySql.Data in a partial trusted environment.
I've added MySql.Data to the GAC (by installing it with the MSI from the mysql.com site). As you can see here:
>gacutil /l | grep -i mysql
MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d,
processorArchitecture=MSIL
MySql.Data.CF, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c4
4d, processorArchitecture=MSIL
MySql.Data.Entity, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc889
69c44d, processorArchitecture=MSIL
MySql.Web, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d,
processorArchitecture=MSIL
>
I've add the following to my web.config:
<configuration>
<system.web>
<trust level="Vevida"/>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
</assemblies>
</compilation>
</system.web>
</configuration>
But I still get the following exception:
Exception Details: System.Security.SecurityException: Request for the permission of type 'MySql.Data.MySqlClient.MySqlClientPermission, MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' failed.
It is thrown when I try to open a connection.
I'm not sure what I can check more.
According to the MySql documentation, I need at least the following permissions:
System.Net.SocketPermission, System.Security.Permissions.ReflectionPermission, System.Net.DnsPermission, and System.Security.Permissions.SecurityPermission
In my trust level I these:
<IPermission
class="SocketPermission"
version="1"
Unrestricted="true">
</IPermission>
<IPermission
class="ReflectionPermission"
version="1"
Flags="RestrictedMemberAccess"/>
<IPermission
class="DnsPermission"
version="1"
Unrestricted="true"/>
<IPermission
class="SecurityPermission"
version="1"
Flags="Execution,ControlPrincipal,ControlThread,SerializationFormatter"/>
As far as I can see in the documentation, this is enough. Also tried to set the SecurityPermission and ReflectionPermission to unrestricted, this didn't help.
Do you have any ideas?

MySqlClientPermission has to be added to the medium trust config as SecurityClass and IPermission. My web_mediumtrust.config addition is:
<SecurityClass Name="MySqlClientPermission"
Description="MySql.Data.MySqlClient.MySqlClientPermission,
MySql.Data, Version=6.5.4.0, Culture=neutral,
PublicKeyToken=c5687fc88969c44d"
/>
<IPermission class="MySqlClientPermission" version="1">
<add connectionString="Server=;Database=;User=;Password=;Port=;Pooling=;"
restrictions=""
KeyRestrictionBehavior="PreventUsage" />
</IPermission>
As also posted on http://www.saotn.org/mysql-connector-net-6-5-partial-trust/

Every time your code opens a MySqlConnection, the MySql client makes a demand for MySqlClientPermission on the connection string. Your application must have this permission, regardless of whether the MySql client assemblies are in the GAC or not.
The permissions listed at http://englishebook.info/1/software-to-download/656-running-connectornet-65-inside-medium-trust-level (the ones that you've mentioned in your question) are the ones need by the MySql client assemblies, not the ones needed by your ASP.NET application. To allow your application to use MySql, you will need to grant it MySqlClientPermission.

Code Access Security problem - what's the issue here?

Background
I have a post-build event which I use to generate some batch files which contain the current version number of our application. The event calls a batch file, which calls a managed app which loads the assembly and uses reflection to find its version information.
Problem
When the post-build event runs locally, every is fine. When it's run under our automated build process, I see the following error in the logs. I know nothing about Code Access Security, and was hoping someone could point out the problem quickly.

Which version of the framework are you using? Older versions don't trust network shares much - so you might need to use "caspol" to enable trust (or move the file locally before running it). More recently, the framework does trust mappped shares (such as Q:\), but doesn't trust UNC shares (\\someserver\whatever) without a "caspol" tweak.
The simplest option, though, is to run the exe from a local drive rather than over the network.
