asp.net-4.5

I've created an asp.net Web Forms site with Visual Studio 2013. Scripts and pages are generated automatically by VS 2013. The problem is that the website doesn't work with the .Net trust level "Medium". It reqires "Full" level. With the "Medium" Level it throws an error: The application attempted to perform an operation not allowed by the security policy. To grantthis application the required permission please contact your system administrator or change the application's trust level in the configuration file. [SecurityException: Request for the permission of type 'System.Security.Permissions

I have a gridview in C# asp.net Web 4.5 Framework that works great until a null valued is passed for a field I am formatting as a date.. here is my template field <asp:templatefield> <HeaderTemplate> <asp:Label ID="lblHeadEmailFirstSendDate" runat="server" Text="1st Email<br />Target Date"></asp:Label> </HeaderTemplate> <ItemTemplate> <asp:Label ID="lblEmailFirstSendDate" runat="server" Text='<%# Convert.ToDateTime(Eval("EmailTargetFirstSendDate")).ToString("MM/dd/yyyy")%>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:Label runat="server" ID="txtEmailFirstSendDate" Text='<%#Convert

From the MSDN page for the PagerTemplate of the GridView control (emphasis mine): Typically, button controls are added to the pager template to perform the paging operations. The GridView control performs a paging operation when a button control with its CommandName property set to "Page" is clicked. The button's CommandArgument property determines the type of paging operation to perform. "Next": Navigates to the next page. "Prev": Navigates to the previous page. "First": Navigates to the first page. "Last": Navigates to the last page. Integer value : Navigates to the specified page number.

I wish to know whether it possible to call async Page_Load in asp.net 4.5 like async controllers in ASP.Net MVC 4. If it is possible, how do we use async events in asp.net? You could use the PageAsyncTask Pretty simple to use. You basically create your async task and then register it with the page and execute it. The link above has a good example. 来源： https://stackoverflow.com/questions/8242375/is-it-possible-to-call-async-page-load-in-asp-net-4-5

I am building an ASP.NET Web Forms web site using .NET 4.5. The error ... The type 'System.ComponentModel.DataAnnotations.Schema.ForeignKeyAttribute' exists in both 'f:\Projects\web sites\RC1Iteration05\packages\EntityFramework.5.0.0\lib\net40\EntityFramework.dll' and 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.ComponentModel.DataAnnotations.dll' I have tried to alias the libraries using ... csc /r:EF_DataAnnotations="f:\Projects\web sites\RC1Iteration05\packages\EntityFramework.5.0.0\lib\net40\EntityFramework.dll" /r:CM_DataAnnotations="c:

On Windows 8 RTM and just installed Vs2012 Ultimate RTM, I'm unable to create a .net 4.5 project nor a .net 4 or 4.5 ASP.NET MVC project. I've done a repair of VS2012, which did not fix it. Is there something obvious I'm doing wrong? Your install is probably corrupted. VS 2012 needs .net 4.5 to run, so something has gone wrong if it's not available. I would try uninstalling and reinstalling. It's brute force but it generally works. I also had the same problem.. Doing the following procedure solved it. Copy the folder \packages\WPT from the visual studio 2012 installer CD to your desktop.

A lot of release notes for Visual Studio 2012 talk about .NET 4.5 and MVC4, but I can't tell if MVC4 is actually part of the .NET 4.5 release. Anybody know for sure? I would love not to have to install MVC separately on my server. No, ASP.NET MVC 4 is baked into VS2012, exactly the same way ASP.NET MVC 3 was baked into VS2010 but not part of .NET 4.0 (there was a separate download that you could install on your servers). But there will also be a separate download of ASP.NET MVC 4 for VS2010 SP1 in which you obviously won't be able to use the .NET 4.5 specific features, such as async/await ,
