I got myself into some problems, when trying to load a solution (GMap.NET), which I had some problems to build. Not sure that matters now though.
I am developing a small system in Visual Studio 2015, which also has a MVC project. When I launch the basic website - more or less just the initial MVC 5 template - through Visual Studio 2015 - that uses IIS Express - I get this error message:
Could not load file or assembly 'System.Web.WebPages.Deployment, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I don't know where the version 1.0.0.0 is coming from! The version I am referencing is 3.0.0.0...
Also - If I publish to my local IIS - it works! I have opened the same solution on two other computers - and there I can launch it from Visual Studio! That means - the problem is on my computer - not in my solution... I am pretty sure.
I suspect that something is messed up on the machine. Maybe in GAC, or some config, but I don't know where... I am thinking on files like this (not that I know much about them):
- C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
- C:\Users\\Documents\IISExpress\config\aspnet.config
- ???
For GAC it doesn't seem that there is the System.Web.WebPages.Deployment.dll. And as it works on the "real" IIS, it must also be ok there.
I also tried to delete all files in 'C:/Users/#user#/AppData/Local/Temp/Temporary ASP.NET Files/vs/'
That should narrow it down to this: - The problem must have something to do with Visual Studio and/or IIS Express - and/or some configuration file. - not a problem with the references in the solution. (I used nuget to install MVC)
Fx. in this file, there is an entry with System.Web.WebPages.Deployment version 1.0.0.0: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config:
<compilation>
<assemblies>
<!-- <remove assembly="System.Web.WebPages.Deployment, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
<add assembly="System.Web.WebPages.Deployment, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> -->`
...
</compilation>
But I already tried to uncomment it. No difference...
So if anybody can give me a hint where to look... files to compare or something, I will appreciate it a lot!
Here is the full message that I get:
