how to host asp.net app locally

I have a ASP.NET website, developed by a freelancer. After developing the website, he directly uploaded the website to my domain. Now, how can I host that website locally on my computer?
I dont have any experience in ASP.NET, however I do know HTML5 and CSS3. Looking at the files, I noticed they are all .cshtml files.
Any help would be great. I have the login credentials of Plesk.
Thanks in advance

You need to use IIS.
To do this, assuming you are on Windows, you need to enable it under the 'Windows Features' setting screen as below:
Check the 'World Wide Web Services' option, and also 'IIS Management Console' under the 'Web Management Tools' section.
After it installs, you will have a new program in your start menu, called 'Internet Information Services (IIS) Manager'.
This is where you setup and configure any local websites. There will already be a default website set up, which you can use, or you can create a new one by right clicking on 'Sites' in the tree on the left, and selecting 'Add Website':
Assuming you just use the default, you will need to copy your application to C:\inetpub\wwwroot\. You will then be able to access this by pointing your browser to http:\\localhost or http:\\127.0.0.1.

Assuming you are working with Windows, you will need to install an IIS on your machine. IIS is a part of Window's features, you can try installing it under:
Control Panel > Program and features > Turn windows features On / Off > Internet Information Services.
In some versions of windows, IIS is not available. In that case, you will need to download IISExpress.
After that - Configure a new website under your IIS, and point the website to the directory in your computer which has the project.

How to deploy an ASP.NET application to localhost using IIS?

I'm trying to deploy an ASP.NET application to localhost using IIS, I've been reading a LOT of tutorials and following them step by step but I just can't seem to make it work...
I created an Application Pool(TestPool) with .NET version 4.0 and gave it every permission to the folder where the application is at.
I then added an application to the Default Web Site and tried to run it at
http://localhost/TestApplication/
But I keep getting:
Any idea what is wrong and how can I solve this?
Versions:
IIS version: 6.2
OS: Windows 8.1
VS 2013 Ultimate: 12.0
VS .NET: 4.6
PS: It's my first attempt at deploying an ASP.NET application so if you need any further information just leave a comment.
EDIT:
It is now running at least thanks to Julian and Marge, but when I run it using VS it has the default view, why isn't it showing when I run it through IIS? When running through IIS it just lists the files:

This error is because your website, in the IIS Server, does not have the Directory Browsing enabled and the default document (default page of the site ex: Default.aspx) configured.
Go to IIS Server IIS > Default Documents and check if the default page of your site is listed, if no, add the page.
Check the related link:
https://support.microsoft.com/en-us/kb/942062

Generally speaking, you do not need to access IIS manager at all to run your webpage on localhost. All what you need to do is right click on the project and then choose properties. In the Web tab you will find Servers section. Make sure the Project Url is something like http://localhost/myproj or simply http://localhost/ then hit Create Virtual Directory. Your webpage should be up by then, and you can access it either in debug mode, or simply by navigating your browser to the Project Url you have chosen.

When you add web application in IIS ex.
That your hostname should be to add in host file which is C:\Windows\System32\drivers\etc"\hosts
ex.
127.0.0.1 test.pln

Hosting WCF service on IIS7.5, receiving 404.0 error

I just received a new development laptop and now I can't get one of my WCF services running on the new laptop.

I dropped a simple "Hello World!" index.html file at the root of the WCF services application. I am able to serve that .html file. My services are under a sub-directory named "Hosts". I also dropped a simple index.html file under that sub-directory - I am able to serve that file as well. I cannot serve any of my .svc files though.
http://localhost/mywcfapplication/Hosts/IncidentService.svc
Anonymous Authentication -- "Application pool identity" is selected
The services are running in their own application pool. About the app pool:
.NET Framework Version: v2.0
Enable 32-bit applications: false
Managed Pipeline Mode: Classic
Identity: ApplicationPoolIdentity
I recently set these services up on a new Windows Server 2012 R2 web server in our test environment (old test server was decommissioned). On the server I had to give the app pool user permission to the directory in the file system (IIS_IUSRS\apppoolname), but my laptop doesn't seem to like this.
I'm receiving a 404.0 error when I attempt to browse to any of my .svc files under this application. IIS tells me the most likely causes are: •The directory or file specified does not exist on the Web server.
•The URL contains a typographical error.
•A custom filter or module, such as URLScan, restricts access to the file.
I have checked and re-checked the URL, and I can serve the .html files. I verified that the .svc files do exist. I'm at a loss. What have I overlooked?

I also followed the steps listed "to verify that the svc file type is mapped correctly in IIS7.0"
HTTP 404 when accessing .svc file in IIS -- "We had a similar problem, and the SVC handler was already correctly installed. Our problem was the ExtensionlessUrl handler processing requests before they reached the SVC handler. To check this - in Handler Mappings in IIS Manager at the web server level, view the list of handlers in order (it's an option on the right-hand side). If the various ExtensionlessUrl handlers appear above the SVC handlers, then repeatedly move them down until they're at the bottom."
I verified that the extensionless handlers were at the bottom.
At the advice from yet another forum post I added a MIME type for .svc. No change.

I got exactly the same issue and finally found a way through it.
The point is that WCF need a integrated pipeline to work properly. In Windows 7's IIS 7.7 I solved the problem by setting the Application Pool to use Integrated Pipeline mode (it was in Classic Mode). But Windows Server 2003's IIS 6 doesn't work with integrated pipeline, so Microsoft .Net uses Web Services Extensions, you could check at IIS 6, right above Web Sites. Ensure that the desired .Net version is allowed in Web Services Extensions. Than you need to register the Service Model extension.
Here´s what I did:
%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
%windir%\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe -i

Consuming Windows Authenticated Service for Client Development in Visual Studio

I have a service hosted in server. The service authentication is using Windows Authentication. I want to use this service in my website development in Visual Studio 2010. When I try to add a reference it says the following error.
“Security settings for this service require Windows Authentication but it is not enabled for the IIS application that hosts this service.”
What should I do to overcome it and be able to consume the service for development?
Note: The error message is obvious. What I am looking for is the best way to overcome this.
Note: When I type the service address in Mozilla Firefox, it asks for my windows credentials -upon entering credentials it gives me the service descriptions. The problem is when I use it via Visual Studio.

If I understand you correctly, your service is already running happily and using Windows Authentication, so it requires the calling application, your web site to also be using Windows Authentication.
When you try and add a reference, VS will start your site in the background using whichever web server is defined in Project Properties. You say that you are starting your site using the built-in web server (also known as Cassini or Webdev). You need to ensure that your site is using Windows Authentication. You do this from the service's Project Properties (right-click on the root folder and select Properties). In there you will see a Web tab which has an NTLM Authentication checkbox - make sure that is checked.
Also, make sure that you use:
<system.web>
<authentication mode="Windows">
...
in your web.config.
However, if you want to use IIS itself, I assume you have it installed and know how to define a web application. Depending on which version of Windows you are running, you may or may not have IIS installed or it may not be installable (using Programs and Features from Control Panel). If you don't have IIS, you can install IIS Express from here: http://learn.iis.net/page.aspx/868/iis-express-overview/
After you have installed IIS and defined your application root, and pointed the directory to your local source folder, enable Windows (NTLM) Authentication for that web app/site. How you do that depends on which version of IIS you are running but it is normally by clicking on the Authentication icon. You probably need to disable Anonymous as well as enable Windows Authentication, so that all requests are forced into Windows authentication. For browsers that do not support automatic NTLM authentication, I also turn on Basic Forms authentication as well.
Once you have an IIS application defined, you can use that for debugging from Visual Studio instead of the built-in web server. You also do that from Project Properties by choosing 'Use Local IIS Server' and selecting the Url of the IIS site you created above. Alternatively, VS can create the IIS site definition for you if it doesn't yet exist.
Either of the above methods should ensure that when VS starts your site to add a reference, it will be using authentication, as well as at runtime. Note that you can add a reference manually, without the need for starting the site. Then you just need to make sure you have Windows authentication at runtime, as described above.

How to enable Windows Authentication on ASP.NET Development Server?

We are trying to host a WCF service via the web. We set the web.config to have the service require windows authentication. The problem we are having is the following:
When we host our service in a regular IIS, the service runs fine and there is no issues with the "Windows Authentication" mode. However, when we try to run it from our developer boxes we get the following error: "Security settings for this service require Windows Authentication but it is not enabled for the IIS application that hosts this service."
Our developers boxes are not hosting the service through the regular IIS but rather through Visual Studio's ASP.NET Development Server. We tried going into the web project properties and said to enable NTLM authentication but that still did not fix it. Does anyone know how to fix it? Does VS ASP.NET Development Server even support Windows Authentication? Is the only option for hosting the service with Windows Authentication is to use IIS and forget about ASP.NET Development Server?

In order to configure IIS Express security settings:
look for the IIS express symbol in the taskbar (system tray).
Right click and select "All Applications".
Click on the name of the site you want to change (although I believe the change is site wide)
Click on the path in the config section below (it will open the applicationhost.config file)
Search for the authentication section and make your changes
Example changes can be found here:

ASP.Net Development Server is very limited. It only serves requests originating from the same machine that it is running on, and it will not serve files that are outside of its application scope. It is based on the Cassini server. Cassini does not support WCF web services. Documentation for ASP.Net Development Server says that it does support NTLM. If you are just browsing to a page from the local machine it should work fine unless the page is referencing an unavailable resource.

I would install and configure IIS on your local dev machine and use that in preference to using the inbuilt webserver. To use local IIS to debug select "User Local IIS web server" on the web tab of the project properties. Using IIS rather than the inbuilt webserver also means that you can configure your app in exactly the same way as it will be configured on the production server and this will reduce the no of potential surprises when you move to the production environment.

The solution to my authorization issue was to go into the F4 project properties and set the following:
Anonymous Authentication: Disabled
Windows Authentication: Enabled
Apparently these properties update the IIS applicationHost.config directly.
