Web Api: System.Net.Http version 2.0.0.0 not found - asp.net-web-api

When I install the NuGet package for WebApi, it gives me version 1.0.0.0 of System.Net.Http, yet it references version 2.
I cannot seem to find version 2 for the life of me. When I download .net 4.5 I get System.Net.Http version 4.0.315.x, but I cannot use that because the Web Api assemblies refer to version 2.0.0.0.
Anyone know where I can find this version 2.0.0.0? I've tried the NuGet package manager, mvc4, .net 4.5, and nothing is giving me version 2.
Thanks in advance.

Add the below configuration inside your Web.config file under <system.web> node (assuming your app runs on .NET 4.5, targetFramework attribute is set to 4.5):
<compilation targetFramework="4.5">
<assemblies>
<add assembly="System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</assemblies>
</compilation>
Also add the below one at the root level under <configuration> node:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" />
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
This should solve your problem.

Adding a wcf ajax enabled file to web forms in asp produces a validation error

I am trying to create a project that uses wcf(ajax enabled) as a communication framework with an ASP.Net project.
When I add a new wcf file to my project an error appears in my configuration file. I have saved my project as Demo and my service file is called Employeeservice.svc.
For details of my configuration file, please read. The error occurs around the tag and the error message reports:
The name attribute is invalid The value employee demoservice is invalid according to it's datatype servicenametype - the enumeration constraint failed.

This should be a warning not an error, it does not affect the build of the project. On my side, my configuration is basically the same as yours, but it's just a warning, and the project can be built normally. Are you creating projects with older versions of VS? If it's VS2012, I suggest you delete the solution .SUO file and rebuild the project, which should solve the problem.

'Could not load file or assembly 'FSharp.Core, Version=4.6.2.0

I upgraded Visual Studio from VS2017 to VS2019. I opened a solution with both C# and F# in it. A C# unit test project references a F# .dll project.
The solution compiles fine but at run time, I get the following message
System.IO.FileLoadException: 'Could not load file or assembly
'FSharp.Core, Version=4.6.2.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The
located assembly's manifest definition does not match the assembly
reference. (Exception from HRESULT: 0x80131040)'
and the inner exception is
Could not load file or assembly 'FSharp.Core, Version=4.6.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its
dependencies. The located assembly's manifest definition does not
match the assembly reference. (Exception from HRESULT: 0x80131040)
I have this in the unit tests app.config:
<dependentAssembly>
<assemblyIdentity name="FSharp.Core" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.6.2.0" newVersion="4.6.2.0" />
</dependentAssembly>
and the unit test project has this in the packages.config
<package id="FSharp.Core" version="4.6.2" targetFramework="net461" />
Is there a missing reference I am not seeing?
Thanks
Bent Tranberg was right
In the test project, I changed the binding redirect to
<dependentAssembly>
<assemblyIdentity name="FSharp.Core" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.6.2.0" newVersion="4.6.0.0" />
</dependentAssembly>
and it worked

Following Introduction to Building Managed ODP.NET I get this error "Unrecognized configuration section oracle.manageddataaccess.client."

Following this tutorial, Introduction to Building ODP.NET, Managed Driver Applications
In the topic "Connect using the TNS_ADMIN Property", when I run I get "Unrecognized configuration section oracle.manageddataaccess.client" error.
I ran into this issue myself in a multi-project solution including a Website. In my case, I have a "Data" project responsible for all Database interaction. It is in THIS project's App.config file that I needed to put my Oracle settings. In fact, the file was already prepared for me with the proper configSections to handle it.
Either way, this is how my App.config file looks now. Either add the missing configSections to your config file, or - if you have multiple projects - ensure you add the settings to the correct project's App.config file.

Where can I find source code of Microsoft.AspNet.WebApi NuGet package?

I have a few question regarding Microsoft.AspNet.WebApi NuGet package source code:
Where is located repository with Microsoft.AspNet.WebApi Nuget package source code.
What commit id corresponds to version 5.2.3 of the NuGet package.
What *.nuspec file was used to create Microsoft.AspNet.WebApi package?
Thanks!
I was looking for the exact same thing and I finally found it. This page lists out the versions and where they correspond in the source. It is v.3.2.3 that maps to 5.2.3.

HOW I MADE MY OWN NUGET PACKAGE AND YOU SHOULD TOO BY Scott Hanselman:
Step 0 - Go get the NuGet.exe command line here. Put it in the Path or somewhere.
Step 1 - Make a folder for your new package, go there via the commmand line and run "nuget spec"
C:\Users\Scott\Desktop\AddMvc3ToWebForms>nuget spec
Created 'Package.nuspec' successfully.

Step 2 - Add stuff to your Content Folder
Since I want my NuGet package to add stuff to folders in my target Web Application, I put whatever I want in a folder called Content. Anything in that will show up in the root of my target project. This can be CSS, JS, CS or VB files, whatever. These files will all get dropped onto the project your package is applied to.
In my project I took the folders from an MVC application and put them in my NuGet folder structure. So, Content, Controllers, Models, Scripts, Views. Copied them right over from an existing blank ASP.NET MVC project.
My NuGet directory where I'm building the package
Step 3 - Decide what needs to be Pre-Processed
However, when my HomeController shows up in your project, Dear Reader, I don't want it to be in the namespace ScottMvcApplication! You want it in MvcApplication54 or whatever your project name is. I need pre-process the source a little to use your project's context, names, namespaces, etc.
For the files I want pre-processed automatically by NuGet, I add a .pp extension. In my example, HomeController.cs.pp.
Preprocessor files with a .pp extension
Then I add a few tokens I want replaced at install-time for that package. For example $rootnamespace$ or $assemblyname$. You can use any Visual Studio Project Property per the NuGet docs.
namespace $rootnamespace$.Controllers
{
public class HomeController : Controller
{
//snip
}
}
Step 4 - Decide what XML elements need to be merged (usually into web.config)
The next preprocessing that is common is adding elements to web.config. This is a nice little feature of NuGet because you just need to make a web.config.transform with the new elements and it will automatically and non-destructively add (and remove) them as needed. Here's my web.config.transform, for reference. Note this is not a full web.config. This is the one I added to my package in the control folder.

Step 5 - Add any PowerShell script you might need, especially for adding references
Almost done. Most package won't need much PowerShell, but some do. You can have an install.ps1 and an uninstall.ps1 and do lots of things. These go in a folder called Tools that's next to Content (not inside.)
Here's my install.ps1.
NOTE: Currently today there's no way to STOP the installation of a package while it's happening, so if you try to install mine on NuGet 1.0 I'll just warn you and ask you to uninstall. In the future there will likely be a pre-install or a dependency check. Hence the version check there.
param($installPath, $toolsPath, $package, $project)
if ($host.Version.Major -eq 1 -and $host.Version.Minor -lt 1)
{
"NOTICE: This package only works with NuGet 1.1 or above. Please update your NuGet install at http://nuget.codeplex.com. Sorry, but you're now in a weird state. Please 'uninstall-package AddMvc3ToWebForms' now."
}
else

$project.Object.References.Add("Microsoft.CSharp");
$project.Object.References.Add("System.Web.Mvc");
$project.Object.References.Add("Microsoft.Web.Infrastructure");
$project.Object.References.Add("System.Web.WebPages");
$project.Object.References.Add("System.Web.Razor");
$project.Object.References.Add("System.ComponentModel.DataAnnotations");
}
Note that in (the future) NuGet 1.2 I won't need this code, I'll just add the references in my NuSpec file directly.
Step 6 - Pack it up
Go back to the command line and run nuget pack
C:\Users\Scott\Desktop\AddMvc3ToWebForms>nuget pack
Attempting to build package from 'AddMvc3ToWebForms.nuspec'.
Successfully created package 'C:\Users\Scott\Desktop\AddMvc3ToWebForms\AddMvc3ToWebForms.0.4.nupkg'.
Step 7 - Submit your package
Next, login to the NuGet Gallery (beta) and Contribute Your Package. Just walk through the wizard and upload the nupkg. You can also get an API Key and use the command line tool to do this automatically, perhaps as part of a build process.
Submitting my app to the NuGet Gallery
That's it. If you've got an open source librar

Packages.config and binding redirects

We're having some build issues due to package issues, but one of our devs got a green build by downgrading a package in the project's packages.config:
<package id="Microsoft.Data.Edm" version="5.6.2" targetFramework="net451" />
This was also added to the project's config file:
<dependentAssembly>
<assemblyIdentity name="Microsoft.Data.Edm" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.6.4.0" newVersion="5.6.4.0" />
</dependentAssembly>
If we have amended the version in the packages.config to 5.6.2, but still point to 5.6.4 in our binding redirect, what version of the Microsoft.Data.Edm assembly is the project going to use?
