Description

Visual Studio item templates for adding HTML5 report viewer fail to add NuGet packages.

Error Message

An error occurred while adding an HTML page with Telerik HTML5 Report Viewer

Error: System.InvalidOperationException: A problem occurred while trying to install the NuGet package "package name"

You can try to update your NuGet client or install the packages manually.

Solution

The fix was provided in R1 2018 Service Pack 3 release (version 12.0.18.416) of Telerik Reporting.

Suggested Workarounds

Download the required packages manually using NuGet package manager:

1. Microsoft ASP.NET 4.0

  • System.Web.dll (4.0.0.0)

  • System.Net.Http.dll (2.0.0.0)

  • System.Net.Http.Formatting.dll (4.0.0.0)

  • Web API 4.0.30506:

    System.Web.Http.dll (4.0.0.0)

    System.Web.Http.WebHost.dll (4.0.0.0) required for hosting in IIS

    System.Web.Http.SelfHost.dll (4.0.0.0) required for SelHosting

2. Newtonsoft.Json.dll 4.5.1.0 (latest available via NuGet is recommended)

You can use a newer WebAPI version by updating the corresponding (Microsoft.AspNet.WebApi.WebHost and Microsoft.AspNet.WebApi.SelfHost) NuGet packages and applying the following bindingRedirects to your application configuration file. Replace 5.1.0.0 with the exact version:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Http" culture="neutral" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.1.0.0"/>
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Net.Http.Formatting" culture="neutral" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.1.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>
