I have added WebView2 to my visual Studio 2017 VB.NET solution with .NET 4.7.2, as per the instructions on microsoft at https://learn.microsoft.com/en-us/microsoft-edge/webview2/gettingstarted/winforms
When I put the webview2 on my form and hit F5 to run it, I always get
System.InvalidOperationException: 'An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.'
and it is stuck in application in break mode.
Can anyone tell me how to make it work please? Or am I stupid and it will only work in visual studio 2019 with core?
Visual Studio 2013 always freezes when XAML parser throw XAMLParseException. It takes sometimes one minute when VS throw exception. It exist some settings how to avoid this behavior?
Everytime I try to load a WPF window/page/userControl, the xaml designer crashes and System.BadImageFormatException is thrown. I've tried to switch the platform to X86 in configuration manager but it does not work. The following is the complete detail of exception:
System.BadImageFormatException
[C:\Windows\Microsoft.Net\assembly\GAC_32\mscorlib\v4.0_4.0.0.0__b77a5c561934e089\mscorlib.dll] The signature is incorrect.
at Microsoft.Expression.Markup.XmlCharType..cctor()
System.TypeInitializationException
The type initializer for 'Microsoft.Expression.Markup.XmlCharType' threw an exception.
Any idea guys?, thank you!
I've resolved the issue by Windows Task Manager and ending the process 'Microsoft Visual Studio XAML UI Designer'. In fact some issues are solved by stopping this process. Visual Studio automatically run this a new fresh instance of this process.
I am using Visual studio 2012 and working with WPF, whenever i create a new widow, then it's designer window is not shown. However,when we run the application,dialog is displayed.
But my question is this why i can't see the designer of WPF dialog while i am writing xaml want to see effects on designer.
Is this an issue with Visual studio 2012 because this happening on all the developer machines in my company.
Is there any patch setup for visual studio other than upate1 and update2 that i have already installed for my visual studio but nothing has been fixed up by now.
I am using VS 2010 SP1
I am having this error after installed the .Net Framework 4.5 developer preview:
While editing a WPF Application, appears the error:
Exception of type 'MS.Internal.Validate+ValidationFailure' was thrown.
Then I uninstalled the .Net 4.5
and now Visual Studio 2010 quit working... now gives me an "unknown error" dialogue when launched
Does somebody also have this issue, or can tell a solution?
I uninstalled .net 4.5
then VS stopped working
then i runned VS 2010 Repair mode
then the installer runned, at some percentage it gave an error
then i closed it, and opened VS 2010, normally.
