VS2015 XAML Designer always System.UnauthorizedAccessException

I having VS2015 and experiencing XAML Designer error of System.UnauthorizedAccessException. I am running on Windows 10 build 10586.
I don't experience the error when I deleted some of the files from the Project. Once I build the project, the UWP app running and the debugger and XAML Designer start to throw error like below:
System.UnauthorizedAccessException
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

I already enabled Developer Mode at the Windows 10.

Update to VS2015 Update 1 definitely fixed up this issue.

From the error message, the user does not have the permission. You could let the application pool under a suitable account (such as LocalSystem).
Here is a Link about this quesiton.

Uninitialized static object called simultaneously by two threads

I have a couple of objects, each of them runs on its own thread, almost simultaneously those objects call another static object which have not been initialized, when I launch the RunWorkerAsyc function, the event RunWorkerCompleted returns with the error
System.Reflection.TargetInvocationException was unhandled by user code
Message: An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
If I only run one of the objects which use these uninitialized, the program works perfectly.
all of this is happening on Design mode, So I don't know how I could design my static class to avoid this. Were already tried the singleton approach, and we still get the same problem.
Any Ideas?

This kind of message apeears when XAML initialization triggers erroneous initialization code (at line 4 in MainWindow.xaml file). The real cause is described in inner exception. It indicates that in Timbre.cs:line 137 a list was accessed with an invalid index.
Since, it shows line number for that file, I assume you have its source code, at least in form of a .pdb file. Than you can set a break-point in there to see what's going on.
An excellent tool for tracking such unclear exceptions is IntelliTrace, but it's only available for VS Ultimate.

How to convert PDF to TIF with GhostScript? [duplicate]

This question already has answers here:
Closed 12 years ago.

Best way to convert pdf files to tiff files
I'm looking for a free library that allows me to convert a PDF document to a (or several) TIFF images. If Tiff is not possible it can also be other images formats.
I read about a way to do this with Ghostscript, but I couldn't find a good explanation. So any hints how to do that?
EDIT:
According to the comment I use this command to execute:
Process.Start("gswin32c", "-dNOPAUSE -q -sDEVICE=tiffg4 -dBATCH -sOutputFile=" + fileName + ".tif " + fileName + ".pdf");
I see that GhostScript is executed in the command line, But I always get an error:

InnerException:
Why this?

You cannot use the Process.Start(string filename) overload to supply command line parameters. From MSDN:
This overload does not allow command-line arguments for the process. If you need to specify one or more command-line arguments for the process, use the Process.Start(ProcessStartInfo) or Process.Start(String, String) overloads.
http://msdn.microsoft.com/en-us/library/53ezey2s.aspx
So try the following instead:
Process.Start(#"C:\Users\Roflcoptr\Documents\Visual Studio 2008\Projects\Prototype_Concept_2\Prototype_Concept_2\bin\Debug\gswin32c", "-dNOPAUSE -q -g300x300 -sDEVICE=tiffg4 -dBATCH -sOutputFile=Report_22_02_2011_21_18.tif Report_22_02_2011_21_18.pdf");

Can you post up the Process.Start() line of code?
I am guessing the error of file not found is coming from the path being incorrect. That being missing the quotes. Because of the space in visual and studio it would assume that "C:\Users\Roflcoptr\Documents\Visual" is the directory.
Process.Start(#"\"C:\Users\Roflcoptr\Documents\Visual Studio 2008\Projects\Prototype_Concept_2\Prototype_Concept_2\bin\Debug\gswin32c\" -dNOPAUSE -q -g300x300 -sDEVICE=tiffg4 -dBATCH -sOutputFile=Report_22_02_2011_21_18.tif Report_22_02_2011_21_18.pdf");
The best way to test this, maybe to first fire up a command prompt and see if you can run that command line successfully before using it in Process.Start() method call.

WPF ProgressBar - TargetParameterCountException

I am making my first WPF application, where I use the Youtube .NET API to upload a video to Youtube using the ResumableUploader.
This ResumableUploader works asynchronously and provides an event AsyncOperationProgress to periodically report its progress percentage.
I want a ProgressBar that will display this progress percentage. Here is some of the code I have for that:
void BtnUpload_Click(object sender, RoutedEventArgs e) {
// generate video
uploader = new ResumableUploader();
uploader.AsyncOperationCompleted += OnDone;
uploader.AsyncOperationProgress += OnProgress;
uploader.InsertAsync(authenticator, newVideo.YouTubeEntry, new UserState());
}
void OnProgress(object sender, AsyncOperationProgressEventArgs e) {
Dispatcher.BeginInvoke((SendOrPostCallback)delegate {
PgbUpload.Value = e.ProgressPercentage;
}, DispatcherPriority.Background, null);
}
Where PgbUpload is my progress bar and the other identifiers are not important for the purpose of this question.
When I run this, OnProgress will be hit a few times, and then I will get a TargetParameterCountException. I have tried several different syntax for invoking the method asynchronously, none of which worked. I am sure the problem is the delegate because if I comment it out, the code works fine (but the ProgressBar isn't updated of course).

InnerException:
Thanks for any help.
Edit: I just found out that if I don't use the Dispatcher and just call set the value directly, it works fine! Is OnProgress called on main UI thread? How can that be?

The uploader (or any async component) can sync with the thread that created it. There are probably a variety of ways to do this, but the one I've seen before goes like this:
public class ResumableUploader {
private SynchronizationContext _syncContext;
public event EventHandler<ProgressChangedEventArgs> OnProgressChanged;
public ResumableUploader() {
_syncContext = SynchronizationContext.Current; //Think of this as the current thread
}
private ReportProgressChanged(int progress) {
if(OnProgressChanged != null) {
_syncContext.Send(s => { OnProgressChanged(this, new ProgressChangedEventArgs(progress)); }, null); //s is any data you want to pass in, here it is unused
}
}
}
Or, slightly more flexible but also more complex for the user/client would be if the user/client supplied the SynchronizationContext at instance creation:
public ResumableUploader(SynchronizationContext syncContext)
