How to create a physical file for the SignalR generated proxy

Question

User-1634604574 posted

can anyone tell me about step 3 and 4 it not clear

As an alternative to the dynamically generated proxy, you can create a physical file that has the proxy code and reference that file. You might want to do that for control over caching or bundling behavior, or to get IntelliSense when you are coding calls to server methods.

To create a proxy file, perform the following steps:

1-Install the Microsoft.AspNet.SignalR.Utils NuGet package.

2-Open a command prompt and browse to the tools folder that contains the SignalR.exe file. The tools folder is at the following location:

[your solution folder]\packages\Microsoft.AspNet.SignalR.Utils.2.1.0\tools

3-Enter the following command:

signalr ghp /path:[path to the .dll that contains your Hub class]

The path to your .dll is typically the bin folder in your project folder.

This command creates a file named server.js in the same folder as signalr.exe.

4-Put the server.js file in an appropriate folder in your project, rename it as appropriate for your application, and add a reference to it in place of the "signalr/hubs" reference.

what part don't you understand.

step 3 is to run the CommandLine  utility included with the nuget package to produce the javascript proxy file.

step 4 is copy the js file to your script folder of choice and change the html page to use this script rather than the dynamic script generated at runtime by the Signal/R middleware.

Hi [e-mail],

I installed Microsoft.AspNet.SignalR.Utils.2.4.1 and the tools SignalR.exe is at:

[solution folder]\packages\Microsoft.AspNet.SignalR.Utils.2.4.1\tools\net40

To generate a physical file for the SignalR generated proxy, run following command first,

cd [solution folder]\packages\Microsoft.AspNet.SignalR.Utils.2.4.1\tools\net40

then enter and run this command:

signalr ghp /path:[solution folder]\SignalRChat\bin

The file server.js will be created in the same folder as signalr.exe

i have this error

SignalR Utility Version: 2.4.1.0
Creating temp directory C:\Users\CentralFoods\AppData\Local\Temp\1e05547a-d202-4f9b-ba36-385c56d50a32
Error: Failed to load assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' referenced by the server. If your application uses a newer version of this assembly, this error is likely due to a missing or inaccurate binding redirect. If your server application has a 'Web.config' or '[AppName].exe.config' file with binding redirects in it, provide the path to that file with the '/configFile' parameter. If you have already provided a '/configFile' parameter, make sure the config file it points to has a binding redirect for 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' within it. See https://aka.ms/about-binding-redirects for more information on binding redirects.

Hi [e-mail],

Please check if your web.config has binding redirect for 'Newtonsoft.Json', like below.

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>

Hi [e-mail],

You can try to uninstall and reinstall Newtonsoft.Json version 6.0.0 manually, and this SO thread discussed similar issue, you can refer to it.
