Visual Studio 2010 designer UnresolvedAssemblyException

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :WPF
I'm having a problem with Visual Studio 2010 that is proving to be extremely difficult to find a solution for. Any help is appreciated. I have a custom library that handles regular expression validation for me. This library sits plainly on our server for everyone to access. In my most recent WPF application I've been learning about ValidationRules. I created my own custom rule that would simply test the input against a supplied regex pattern. Here's an example of the XAML. <TextBox Grid.Column="2" VerticalAlignment="Center" Style="{StaticResource sTextBox}" Validation.ErrorTemplate="{StaticResource TextBox}" SourceUpdated="ProductQuantity_TargetUpdated"> <TextBox.Text> <Binding Path="Quantity" Mode="TwoWay" NotifyOnValidationError="True" NotifyOnSourceUpdated="True" NotifyOnTargetUpdated="True" ValidatesOnDataErrors="True" UpdateSourceTrigger="PropertyChanged" ValidatesOnExceptions="True"> <Binding.ValidationRules> <vr:RequiredField Label="Quantity" /> <vr:RegularExpression Label="Quantity" ValidationPattern="NumberAbsoluteNoDecimals" /> </Binding.ValidationRules> </Binding> </TextBox.Text> </

WPF Designer (in VS 2008 and VS 2010) crashes with Visual Studio

Good day all. I have the following question: WPF designer in both VS 2008 and VS 2010 crashes with Visual Studio when I try to edit UI form. Moreover, it crashes even when I try to save .xaml.cs file. Meanwhile, Winforms and Dataset UI editors work as usual. Are there other people met this issue? And how could I fix up this problem? Deleting the .suo file, uninstalling silverlight, repairing visual studio, and further googling did not help me. Thanks in advance.

Improving the Start-up Performance of the WPF and Silverlight Designer in Visual Studio 2010 Beta 2


IMPORTANT NOTE: the Beta and Release Candidate builds of Visual Studio 2010 are now obsolete, since Visual Studio 2010 has now released to manufacturing.

See http://www.microsoft.com/visualstudio/en-us/download


NOTE: The Release Candidate and RTM builds of Visual Studio 2010 does not need this configuration change

This post is to let you know about a configuration change (registry switch) which you can use to improve the startup performance of the WPF and Silverlight Designer in Visual Studio 2010 Beta 2.

1. Since this was a late-breaking change, you may experience some instability or increased Virtual Memory usage in some Visual Studio scenarios when using it. If you see such instabilities, please try removing the configuration change, and let us know about the problem you saw (you can do this by replying to this posting or by raising a bug on Connect).

2. You should only make this configuration change if you are a regular user of the WPF and Silverlight Designer, and are experiencing poor performance with it.

3. This configu

Visual Studio 2010 Hangs in Designer, Memory Usage Grows


After switching to the web designer, VS2010 sometimes hangs. If I look at the Resource Monitor, I see that devenv.exe is consuming 50% of the CPU (on a dual-core machine), and its memory usage keeps slowly growing. Since VS is unresponsive, I end up killing the devenv process and restarting VS.

The problem occurs about 1-3 times a day. I have not found a way to specifically reproduce the problem, but it appears to happen most on complex web pages that include UserControls. All pages in this project also use Master pages, if that helps.

Since upgrading from VS2008 to VS2010, I've noticed a number of odd problems. This one actually forces me to kill the devenv process and restart VS2010, and so is particularly disruptive. I did not have any similar problems under VS2008.

ASP.NET 4 and Visual Studio 2010 Web Development Beta 2 Overview

Many exciting changes for ASP.NET are coming in the .NET Framework version 4. This document gives an overview of many of the new features that are included in the Beta 2 release of the .NET Framework 4 and of Visual Studio 2010.

Visual Studio 2010 Beta 2

This is a big deal. This isn't ".NET 3.6" - there are a lot of improvements of .NET 4, and it's not just "pile on a bunch of features so you get overwhelmed." I've been working with and talking to many of the teams involved and even though it's a cheesy thing to say, this is a really customer-focused release.

ASP 4 - Whirlwind Tour around .NET 4 (and Visual Studio 2010) Beta 1

There's a lot of stuff that's new and added in .NET 4, but not in that "overwhelming-I-need-to-relearn-everything" way. More in that, "oh, this is way easier/simpler now" way. Like, moving data around with ADO.NET DataServices is easy, binding with client templates is easy, there's F# if you need it, the "dynamic" keyword if you need it, Silverlight's already installed, oh, and the parallel stuff will freak you out, but in a good way.

Short Overview of SharePoint Features in Visual Studio 2010

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.

About Dynamic Data in Visual Studio 2010 / .NET 4



Does anybody here have any pointers to screencasts, demos, webcasts for the latest enhancements in Dynamic Data as listed in above link? I'm repeating them here for ready reference :


  • EnableDynamicData method which enables Dynamic Data features in existing ASP.NET applications and DataSource controls
  • A new QueryExtender control, contained in the sample projects to simplify common data filtering operations. It supports a rich ASP.NET declarative query syntax that makes it easy to do things like search data for text or have filters based on ranges
  • A new Dynamic Data filter model that enables the developers to apply templates to pages just like field templates (including user defined filters)
  • New field templates of Email, URL and Enum columns
  • Support for inheritance in Entity Framework and Linq to SQL
  • Support for many to many relationships in Entity Framework
  • New Entity Templates which allow fine control over how an object is displayed and edited
  • DynamicHyperLink control for building links to tables and actions
  • Declarative support for D
