问题 As soon as I simply open my Asp.net MVC 3 project in Visual Studio 2013 Ultimate, IISExpress starts serving up zero byte pages. That is, the content-length is 0 and the request body is empty. Close VS, and the pages are served up correctly. I typically launch IISExpress myself from the command line. It serves up my application no problem. Once I open my project in VS 2013, suddenly empty pages are served up. Http response code is 200. I can still attach and then debug/step through. I see my

问题 As described in another SO post of me I saw a strange behaviour of my application after moving from VS 2008 (.net 3.5) to VS 2013 (and using .net 4.0, not 4.5). I found that the static constructor (cctor) of a class was not called any more. Therefore I broke the application down into a small test program: DLLs testAssembly_2-0 and testAssembly_4-0 (similar content; testAssembly_4-0 has names with 40 instead of 20 ) namespace testAssembly_20 { public ref class Class20 { public: Class20 () {

问题 I have a form. All I want to do is display a section of that form on another form. I don't want it to be functional or anything. I basically just want it to be a picture. Is that possible, and if so, how? Like display = new display(form, new rectangle(X1, X2, Y1, Y2)); Is that a possibility? 回答1: Yes you can do: Bitmap bmp = new Bitmap(myWidth, myHeight); myForm.DrawToBitmap(bmp, new Rectangle(x, y, bmp.Width, bmp.Height)); And then pass this bitmap to the other form. 来源： https:/

问题 I'm using Visual Studio 2010 with .NET 4.0. I have a windows service that is installed from a Visual Studio Setup Project. In the setup project I have the RemovePreviousVersion property set to True. In the project that contains the service I have an installer class that will be used to stop the service when upgrading from a previous version. So when upgrading the software the service will already exist and could be running. If it is running then during the installation the installer prompts

问题 I'm maintaining a WPF based application which contains a WinForms based WebBrowser control that based on the IE web browser control. When we deploy, we have had to also supply Microsoft.mshtml.dll and do some custom configuration stuff for our ClickOnce publishing process as well in order to get things to work.
