Deploying Entity Framework WPF Application - c#

I've made a WPF application that uses EF6 code first database.
I've been doing it all in Visual Studio and using the default LocalDb.
The client wants to test what i've doe so far. I've tried ClickOnce application installation to my development PC. The program simply doesn't start, no window opens.... absolutely nothing happens.
I've deployed a simple WPF app and it works right away so i surmise it's the EF component.
How do i get some sort of output log, or debugging so i can see what the error is?
Any ideas on how to fix the error?
Where does it get installed to?
How can i attach the debugger?

UPDATE 4 - Using DbConfig
Earlier today i ran the SQLExpress install manually and just went with the defaults for all options.
I've converted to DbConfig based on what i could find on the msdn update. This works again in visual studio. Making the Db at the name i gave to the DbContext Constructor.
Just to be sure i uninstalled the programs ClickOnce install. Reinstalled. When i was fiddling earlier i noticed this, but i now get a dialog box saying "Cannot Start Application || Application cannot be started. Contact the application Vendor". Unlike earlier where the app would run and then crash. This new way gives me no custom exception log, but i do get details shown below:

SOLUTION/ / WRAP UP
Thanks to grek40. Particularly his exception catching code. This allowed me to start making changes to find the errors. Prior to that, the windows logs didn't help at all.
What put me past the hurdle was using the DbContext definition he suggested. For some reason using the default DbContext constructor and a connection string seemed to make ClickOnce install expect to find an mdf file; even though attaching one wasn't specified.
The exception catch code also allowed my my debugging in release mode to find some odd exceptions (once that didn't apply to debug mode, or that made any sense to me). I've now turned off the offending code so i could proceed; the click once install now works.

I want to make sure that you actually do everything possible to catch and log the occuring exception.
Make sure to register an exception handler in App.xaml with DispatcherUnhandledException
<Application
x:Class="[Your Stuff]"
DispatcherUnhandledException="Application_DispatcherUnhandledException">
</Application>
Implement some logging in the handler (inside App.xaml.cs). It should be something that summarizes the exception messages of all inner exceptions as well as their stack traces. Just write that information to some sort of log file (C:\Temp\MyAppCrashes.log in my example).
private void Application_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
var sb = new StringBuilder();
AppendExceptionMessages(sb, e.Exception);
AppendExceptionStacktraces(sb, e.Exception);
File.AppendAllText(#"C:\Temp\MyAppCrashes.log", sb.ToString());
}
private void AppendExceptionMessages(StringBuilder sb, Exception e)
{
while (e != null)
{
sb.AppendLine("============== Exception ===============").AppendLine(e.Message);
e = e.InnerException;
}
}
private void AppendExceptionStacktraces(StringBuilder sb, Exception e)
{
while (e != null)
{
sb.AppendLine("======== Exception Stacktrace ==========").AppendLine(e.StackTrace);
e = e.InnerException;
}
}
I hope this reveals some more information, if it's not enough, make sure to register a Startup handler in App.xaml instead of a StartupUri. In the startup, before creating any window, create an instance of your db context, call db.Database.Exists() and db.Database.Initialize(true), make sure to check the Exists return value and wrap the calls in try-catch. Ofcourse, write logging details if any exception is caught.
So far for now, hope you find anything with that approach.

Enterprise Library Logging - Visual Studio - MONO - MacOSX - NotImplementedException

I'm trying new VisualStudio for Mac (Mono 6.0.0.296) with With Microsoft Enterprise Library 6.0.1304. Unfortunatly im not able to use it since an "NotImplementedException" is raised.
I have been using Enterprise Library for many years but in Visual Studio (Windows Env.) and it is great but when i tried to use the same under mono everything seems not working.
After some search i can see that mscorlib.dll for MONO dows not support WindowsIdentity "User" Property.

From The log, you can clearly see that System.Security.Principal.WindowsIdentity.GetCurrent breaks the rule...
Could you Kindly help me on this?
Did anyone try to use Enterprise Library with Mono on MacOS?
Is somewhere present a workaround?
Thanks a lot for your help and time.
Regards,
finally i have managed such situation.
First of all, thanks to all comments, those helped me lot of with resolution.
Basically, i had to change a part of MEL 6 code and then i could use it without issue.
As previously suggested by #SushiHangover, i took MEL 6 source code and i started to analyze... i have fould a part of the code that was calling SecurityIdentifier User inside mscorlib.dll
What i did is:
- download MEL 6 source code
- open it with Visual Studio for MAC
- delete all Test projects and files not supported by the engine
- compile till everything is fine
Once you have your prj compiled, find and comment "Impersonation" section of the below section:
private void ProcessLog(LogEntry log, TraceEventCache traceEventCache)
{
// revert any outstanding impersonation
//using (RevertExistingImpersonation())
//{
var items = new ContextItems();
items.ProcessContextItems(log);
var matchingTraceSources = GetMatchingTraceSources(log);
var traceListenerFilter = new TraceListenerFilter();
foreach (LogSource traceSource in matchingTraceSources)
{
traceSource.TraceData(log.Severity, log.EventId, log, traceListenerFilter, traceEventCache, ReportExceptionDuringTracing);
}
//}
}
Code Sample Image Link
After that, recompile, use compiled dll into your own project and it will finally work.
If you have any further question or dubt, please let me know and i will be happy to reply.
Have a great working day,
Regards,
Florin

Occasional error: The type 'HttpRequestMessage' is defined in an assembly that is not referenced

I am working on an old WebForms project.
Occasionally it won't build
The type 'HttpRequestMessage' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
The exception above is thrown on Request on this line
public class MyController : ApiController
{
[System.Web.Http.HttpPost]
public string Test()
{
string data = Request.Content.ReadAsStringAsync().Result;
}
}
To be able to run the website, I simply have to Rebuild Solution (without changing anything at all).
Any idea what may be causing it?
Add below code in you web.config
<configuration>
<system.web>
<compilation>
<assemblies>
<add assembly="System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</assemblies>
</compilation>
</system.web>
</configuration>

Getting a strange exception with the MS Exception Handling Block

I've created a very basic Logging block and Exception Handling block. In my code, I went to go test the Exception Handling (I know the Logging block works) with the following:
public void RunScriptClean()
{
try
{
throw new FileNotFoundException();
}
catch (FileNotFoundException ex)
{
var b = ExceptionPolicy.HandleException(ex, "Logging Policy");
if (b)
throw;
}
}
However, on the very first line of the catch block, I get this long winded exception and my application crashes:
Exception occured: The current build operating (build key Build Key [Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicyImpl, Logging Policy]) failed: The type 'Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' cannot be resolved. Please verify the spelling is correct or that the full type name is provided. (Strategy type ConfiguredObjectStrategy, index 2).
I have absolutely no idea what it's referring to when it says the type cannot be resolved. I've added references to Microsoft.Practices.EnterpriseLibrary.Common/ExceptionHandling/Logging and Ms.Practices.ObjectBuilder2. This one class has using Microsoft.Practices.EnterpriseLibrary.ExceptionHandling included at the top.
Added a screenshot of the configuration tool looking at my AppConfig file:
I'm sure I'm missing something basic, but it's tough to find a tutorial for EAB 4.1-- CodeProject has a lot for the original versions but I couldn't make much of them...
Edit I tried creating a new Formatter and naming it TextExceptionFormatter but that didn't change anything. Wasn't sure if maybe some how the FormatterType property on my Logging Handler was tied to that node.
And the actual block of XML from App.config:
<exceptionHandling>
<exceptionPolicies>
<add name="Logging Policy">
<exceptionTypes>
<add type="System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
postHandlingAction="NotifyRethrow" name="Exception">
<exceptionHandlers>
<add logCategory="General" eventId="100" severity="Error" title="Enterprise Library Exception Handling"

name="Logging Handler" />
</exceptionHandlers>
</add>
</exceptionTypes>
</add>
</exceptionPolicies>
</exceptionHandling>
I found this SO question: Cannot resolve type runtime error after registering the Enterprise Library into the GAC but even after changing the Version segment of the fullName attribute my app still behaves the same.
Alright, I was able to find a sample application that used the Logging handlers. Turns out I needed a reference to ExceptionHandling.Logging:
Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging ****
Microsoft.Practices.EnterpriseLibrary.Logging
Microsoft.Practices.ObjectBuilder2
Where as I only had a references to:
Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling
Microsoft.Practices.EnterpriseLibrary.Logging
Microsoft.Practices.ObjectBuilder2

"An error occurred creating the configuration section handler for" -

We're getting an odd error in our Test environment with a custom configuration section.
This is for a Windows Service running on a Enterprise Server 2008 r2 64 bit with SQL Server 2008 in both dev and test environments.
This section configures our shared code library to send email out to interested parties whenever an error is handled and published with code like this:

This exact same configuration works fine in our DEV environment. These are identical environments to the best of my knowledge, and both services are running under the same code base.
Any ideas as to what the permissions failure is? One thing we are working on doing is creating the custom log but even when we remove the default publisher which tries to write to a custom log that doesn't exist, the process still fails.
Turns out this was an obscure installation issue.
We uninstalled the service with the old exe, and reinstalled using 64 bit 4.0 framework and the issue went away.
Its the framework setting in the build configuration
Not directly related to your scenario, but if you get the same exception whilst attempting to run a .NET 4.0 app from a network share, then you need to install this hotfix:

Using a profile property of type List in .NET Membership

I'm working on a C# Webservice that needs to provide authentication as well as roles and profile management. I need each profile to have a property of type List. The profile section in the web.config looks like this:
<profile defaultProvider="MyProfileProvider" enabled="true">
<providers>
<remove name="MyProfileProvider"/>
<add connectionStringName="MySqlServer"
applicationName="MyApp"
name="MyProfileProvider"
type="System.Web.Profile.SqlProfileProvider" />
</providers>
<properties>
<add name="Websites" type="System.Collections.Generic.List<String>" serializeAs="Binary"/>
</properties>
</profile>
However, when I start the webservice and try to access that property it returns the following error:
System.Configuration.ConfigurationErrorsException: Attempting to load this property's type resulted in the following error: Could not load type 'System.Collections.Generic.List<String>'. (C:\Projects\MyProject\web.config line 58) ---> System.Web.HttpException: Could not load type 'System.Collections.Generic.List<String>'.
Is there a way to use a generic collection for this purpose?
After more searching I finally managed to find the answer. The solution is to use the type name qualified by its namespace. This means that for my issue I used:
<add name="Websites" type="System.Collections.Generic.List`1[System.String]" serializeAs="Binary"/>
I also found out that it is also possible to specify classes defined in other assemblies. To use those you need the assembly-qualified name. For example, that would be "System.Collections.Generic.HashSet`1[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" for a Hashset of Strings.
