Wcf large data file

I am trying to upload an image file in base64 format from a angular app. The app is working fine for small images but wcf is giving error of entity too large error for images larger then 200kb. My webconfig file is like this.

I tried previous answers on this site but none seems to be working. I am using framework 4.6.

I suspect you need to add a binding element for the webHttpBinding binding and set maxReceivedMessageSize to something large. The default value is 65536 bytes.
This needs to be set in the system.serviceModel node in the web.config
Below is an example xml set to 5MB
<bindings>
<webHttpBinding>
<binding name="largeMessage" maxReceivedMessageSize="5000000" maxBufferPoolSize="5000000" maxBufferSize="5000000" closeTimeout="00:03:00" openTimeout="00:03:00" receiveTimeout="00:10:00" sendTimeout="00:03:00">
<readerQuotas maxStringContentLength="5000000" maxArrayLength="5000000" maxBytesPerRead="5000000" />
<security mode="None"/>
</binding>
</webHttpBinding>
</bindings>
Could you try updating the services node to explicitely use the binding config (bindingConfiguration attribute equals the binding name attribute). I don't think this is really required as there is only one binding but lets try being explicit.
<services>
<service name="ExamService.ExamService" behaviorConfiguration="serviceBehaviors">
<endpoint address="" contract="ExamService.IExamService" binding="webHttpBinding" bindingConfiguration="largeMessage" behaviorConfiguration="web" ></endpoint>
</service>
</services>
UPDATE
Not sure whats going on here. I made a quick dummy service to replicate the problem.
namespace LargeMessageService
{
[ServiceContract]
public interface ILobService
{
[OperationContract]
[WebGet]
string EchoWithGet(string s);
[OperationContract]
[WebInvoke]
string EchoWithPost(string s);
}
public class LobService : ILobService
{
public string EchoWithGet(string s)
{
return "You said " + s;
}
public string EchoWithPost(string s)
{
return "You said " + s;
}
}
}
When I had a configuration without the binding defined it failed with a 413 as you are seeing. When I added the binding it worked. My full web.config with binding:
<appSettings>

I was using IISExpress and calling it through Postman by calling the EchoWithPost operation with an xml.
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Hello</string>
replacing 'Hello' with a large string (approx 500K)
Try getting this one to work and if it does its a case of trying to work out the difference between this one and your one. Let me know how you get on.

I think you are trying to consume an asmx web service as a WCF service in your client.
When you add the service reference, try as below -
And delete all the config and binding info in your client app.

WCF hosted on IIS express ssl enabled

I've been banging my head for a week now, I am trying to run a WCF service on IIS express and do a GET from the browser, everything works fine in HTTP, but the minute I try the HTTPS it fails with
HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
I have tried every single config file in stackoverflow answers I also tried this I know it is for IIS but I can't see why it is not working On IIS express. here my config file:

I am sure I am missing something really silly, but I am really out of ideas, your help is much appreciated.
Update
I can get to my .svc with https but when i try a get from a browser or post from fiddler nothing is working

Use ServiceBehaviour like below-
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
</behavior>
This may help you.

In WCF Service Config file add following :
<binding name="secureHttpBinding">
<security mode="Transport">
<transport clientCredentialType="None" />
</security>
</binding>
In client application config file add following :
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
This will allow you to host and access WCF service with HTTPS protocol.

Stacked up with web service configuration

I'm currently stacked with the web service that im creating right now. when Testing it in local it all works fine but when I try to deploy it to the web server it throws me the following error
An error occurred while trying to make a request to URI '...my web service URI here....'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.

This sounds like the error you get when you are trying to use silverlight to access a webservice from where it is not hosted. If this is the case you need to add a clientaccesspolicy.xml to your web application folder.
MSDN article on allowing crossdomain access for a silverlight application.
