Why is this newly created MVC application throwing this error?

All I did was make a new MVC project in Visual Studio called Fadi's Project. I didn't touch any code but it threw this error when I ran the application. I tried debugging but no breakpoints where being hit. I tried to find a solution to my specific problem and while there are many like it none of the other fixes where the same.

I think it is the apostrophe in your website name. Take that out and try again.

as it is saying in the error itself: The given assembly name or codebase was invalid. Change that name and try again

Blogengine.net asp.net exception

I was using blogengine.net and was configured to run on XML provider. But today when I opened the site, it's giving an exception.
You must reset your password using ALTER USER statement before executing this statement.
[MySqlException (0x80004005): You must reset your password using ALTER USER statement before executing this statement.]
That's weird because I'm using XML as provider and this exception is saying that I'm using SQL. I have also viewed web.config with these lines
<BlogEngine>
<blogProvider defaultProvider="DbBlogProvider" fileStoreProvider="XmlBlogProvider">

Wrong assembly version from Owin dependency

I need to switch a specific library that was from version 16.1 before to version 15.0. I did this by removing the higher version and installing the lower version by nuget.
When building, the correct dll (15.0) is created in the bin-directory. But I receive the following error when starting the (web) application:
[FileLoadException: Could not load file or assembly 'Microsoft.SharePoint.Client.Runtime, Version=16.1.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies.

What is most irritating about this error is that the Owin-package seems to cause this error. But Owin should not have a reference to Microsoft.SharePoint.Client at all according to the NuGet-documentation.
Or is this whole strack trace misleading and Owin does not have to do anything with this problem?

I encountered the same problem. For me the problem got solved by removing the .dll that was causing the error from the bin directory. (In my case it was Microsoft.Online.Sharepoint.Tentant.dll)

I encountered the issue as well. It can be circumvented by specifying the startup class in the web.config, so that Owin does not try to search for the correct startup class.
The appSetting element overrides the OwinStartup attribute and
naming convention. You can have multiple startup classes (each using
an OwinStartup attribute) and configure which startup class will be
loaded in a configuration file using markup similar to the following:
<appSettings>
<add key="owin:appStartup" value="StartupDemo.ProductionStartup" />
</appSettings>
The following key, which explicitly specifies the startup class and
assembly can also be used:
<add key="owin:appStartup" value="StartupDemo.ProductionStartup, StartupDemo" />
Futher details can be found in the documentation.

ServiceStack: Deployment causes FileLoadException, can't load System.Runtime.Serialization

I've got a very simple ServiceStack service running, from a path /api/Translate/.... This works perfectly locally. I can view XML, JSON, etc.
However, when I deploy the project to the live environment, calling the service results in:
<TranslateResponse xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="">
- <ResponseStatus>
<ErrorCode>FileLoadException</ErrorCode>

</TranslateResponse>
The TranslateResponse being my otherwise healthy DTO. The ResponseStatus is not mine. I have checked .NET version targetting and have set System.Runtime.Serialisation to "Copy Local" and manually included the DLL in the /bin folder.
But it still does not work. Where am I going wrong?

Solved it.
It was the inclusion of a Project built using the Portable Class Library project. That thing seemed too good to be true. Have removed (which solves other issues, chiefly MVVM implementation) and all works.

String was not recognized as a valid DateTime, asp.net

,Hi,
I have a asp.net and c# website.
In the asp code I use
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"></asp:ScriptManager>
when I run my project I get this error:
String was not recognized as a valid DateTime.
I am not using any dataTime things, on my site.
Then when I do refresh to the page the error disappears.

What can be the issue?

You're referencing a library with a [TypeLibraryTimeStampAttribute] that has an invalid date passed to it.
Find that library and fix or remove it.
In general, it is a bad idea to use WinForms libraries in ASP.Net.

remove all AxInterop.*.dll files from bin folder of web application
