Error when Trying to Run an WPF Program: XamlParseException occurred

PROBLEM:

This error is a very difficult one to identify.  It took me a couple of hours and remembering what code I added within the last compile.  Note:  This error does not occur when you compile, but when you run the application. 

What it turns out to be is when you write the following XAML code for a Window Form in WPF (Windows Presentation Foundation). 

The error was on Line number 14 but not line position 9… as the above error display shows.

Code Snippet

1. <Window
2.     x:Name="PullDraftDetail"
3.     x:Class="PullDraftDetail"
4.     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation&quot;
5.     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml&quot;
6.     AllowsTransparency="True"
7.         Title=""
8.          mc:Ignorable="d"
9.         xmlns:d="http://schemas.microsoft.com/expression/blend/2008&quot;
10.         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006&quot;
11.         d:DesignHeight="200" d:DesignWidth="700"
12.         SizeToContent="WidthAndHeight"
13.         WindowStartupLocation="CenterScreen"
14.         WindowStyle="None" Background="{x:Null}" Icon="/PullDraft_WPF;component/images/Book_JournalwPen.ico"
15.     >

This code produces the following form in “Design View”.

What I wanted is to make the Window transparent and display the “GroupBox" and all the other elements by setting the Window’s “Background=”{x:Null}”

But, when I added the “Icon=”/PullDraft_WPF;component/images/Book_JournalwPen.ico” I got the error “XamlParseException occurred”.  By the way… I did not need the “Icon” element because the Window was transparent anyway.

Solution:

I removed the Icon element and everything ran fine.

If you cannot see in VS 2010’s Solution Explorer the Icons from TFS (Team Foundation Server)

Problem:

Team Explorer can connect and shows the server and projects.  Source Control Explorer shows the source files and the state of check in/out.  But in Solution Explorer, there is nothing!  The red check marks are gone, the blue locks are gone.  Right click a solution or project or file and there are no source control options.

 

 

 

 

 

 

Solution:  http://social.msdn.microsoft.com/Forums/en/tfsgeneral/thread/58987d05-38d0-4056-82d7-f036adb7b2f3

When you try to connect to the TFS server and its offline then if you choose to still work on the solution you must eventually “Go Online” by right clicking the solution name in the Solution Explorer and select “Go Online”.

Change Source Control prompts: "The current solution is associated with source control but is offline.  Would you like to completely disassociate the solution from source control?" , because you did not perform the go online in Source Explorer.

When you right click the solution name in the Source Explore, can you select Go Online item? If you can, you can perform such as the check in/out operations.

Offline means if you cannot connect the TFS Server, you can also edit your solution, and when you connect the TFS Server, you can go online and perform the check in /check out.

There is a video about work offline with TFS, you can see: http://msdn.microsoft.com/en-us/vstudio/bb898913.aspx

How To: Turning On or Off a Control with IsEnable and the “Not” Command

You can simplify the following VB.NET code snippet by using NOT instead of IIF

1.        DeleteButton.IsEnabled = IIf(DeleteButton.IsEnabled = True, False, True)

can be restated in a simplified syntax as
