I am using Visual Studio 2010. I was debugging a web application and an exception happened and VS 2010 froze. I ended the VS 2010 in the task manager and when I went back to developing, I found on every form for every ASP.net control I get:
Error Creating Control -
Error HRESULT E_FAIL has been returned from a call to a COM component.
Also I am unable to edit the form or add anything from the toolbox.
Any help on this matter will be appreciated.
After I imported a VS 2008 web project to VS 2010, I can't view aspx pages that have master pages in design mode. The page design mode displays "error creating control - contentplacehoder1 object reference not set to an instance of an object." The project builds and runs fine though. I have only one master page that all other aspx pages reference and I don't have any nested master pages. Can anybody help me with this? Thanks in advance.

I have Visual Studio 2010 Ultimate. And I've downloaded and installed Sql Server 2008 R2 Express.
I'm going through a Silverlight trainging module and using the
Silverlight Business Apps: Module 2 - WCF RIA Services
example application. The database included (as an .mdf file) won't attach in the project. I get this:
"Connections to SQL Server database files (.mdf) require SQL Server 2005 Express or SQL Server 2008 Express to be installed and running on the local computer. The current version of SQL Sever Express can be downloaded at the following URL:......"
But of course, I have the most recent version. Now I did have SQL Server 2005 Express Edition installed before and it wasn't working either. I got a different error concerning the version of the .mdf file. In an attempt to resolve this
I un-installed the 2005 version. Now I've got a functioning default instance of Sql Server, but I notice it's not listed as .\SqlExpress as the 2005 version was.
Can someone help me get this working? Do I need to change the name of the SQL Server instance in order to for Visual Studio to be able to attach?
I also can't attach the file using SQL Server Management Studio, but I think that's because the file has the path to the Log file somehow
IMPORTANT NOTE: the Beta and Release Candidate builds of Visual Studio 2010 are now obsolete, since Visual Studio 2010 has now released to manufacturing.
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
I added a visual web part item to my solution. I'm looking to drag some controls on to the design surface from the toolbox but they're not there. For example, linqdatasource control and datapager control. I tried to create them in
the markup up but all I get is 'cannot render control' or 'unknown server tag.'
At the top of my .ascx file I have:
<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%@ Assembly Name="Microsoft.Web.CommandUI, Version=188.8.131.52, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

I don't know if this is the right forum but I'm having some issues with Visual Studio 2010 on Windows 7 x64. I can create and design a WPF project just fine but when I try to do Silverlight, I get the following error in the designer. I can't
access the visual designer or the XAML.
Could not find Microsoft Silverlight SDK v4.0. Plase make sure that the correct version of the Microsoft Silverlight SDK has been installed.
