HowTo: Tell IE to use compatibility mode without editing your web pages

at http://www.mono-software.com/Mono/Pages/Discussion/dtopic/_YyUBIlx5kiqHaNqAQeltg/br-brake-bug-in-IE11-and-clipflair-text-editor/

one reads:

We are using Telerik’s rich text editor (RadEditor), and it seems that RadEditor has specific behaviour regarding insertion of break tags.

To circumvent this issue please try to add host header in ISS 7 (website level):

Name = "X-UA-Compatible"
Value = "IE=EmulateIE10"

Or, you can insert Html Meta tag on a PreRender event (of Page that uses RadEditor):

HtmlMeta meta = new HtmlMeta();

meta.Attributes.Add("http-equiv", "X-UA-Compatible");

meta.Attributes.Add("content", "IE=EmulateIE10");

Page.Header.Controls.Add(meta);

 

This is a very handy trick, one can open up a website at IIS console and open HTTP Response Headers node and then add the Name / Value pair X-UA-Compatible / IE=EmulateIE10 to force say Internet Explorer 11 to behave like Internet Explorer 10

To confirm it works, press F12 to show developer tools in IE11 and see at the right that it says “IE10” instead of “Edge” at the HTML engine selection dropdown list (compatibility mode).

Set default document for IIS via web.config at Silverlight Web project

When you tell the Visual Studio IDE to generate a web project (instead of just using an autogenerated page) for a Silverlight project, it creates a project named SilverlightAppName.Web with a SilverlightAppNameTestPage.aspx (ASP.net) and an SilverlightAppNameTestPage.html. Either one can be served from a web server (obviously the .aspx one from IIS or any web server that supports ASP.net at the server-side) to run the Silverlight app in the browser, or for debugging from within Visual Studio (with the included test web server [Cassini] or IIS).

Note that at that Web project’s Properties, there’s a tab Silverlight applications, where Silverlight apps hosted by that Web project are listed. If you add more there, Visual Studio will generate respective pages for them, in the pattern mentioned above.

By right clicking one of those two pages you can select “Set as Start Page” to set the default page that “Start” or “Start without debugging” uses. However that setting isn’t replicated to the web.config file automatically so that after publishing (by right clicking the web project and selecting “Publish”) that Web project to say a subfolder under “wwwroot” of IIS (or deeper in the web folders hierarchy).

If it was doing so, you would be able to just visit that folder and have IIS (or any other web server that supports the web.config scheme) serve the wanted page as the default document (instead of showing a can’t browse folder error or displaying the folder contents if Directory Browsing has been enabled at IIS console for that folder or some ancestor of it [and has not been overridden to disable at that folder])

However, you can edit web.config yourself to achieve that, like below:

<?xml version="1.0"?>

<system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.webServer>
<defaultDocument>
<files>
       <clear />
        <add value="
SilverlightAppNameTestPage.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>

</configuration>

Troubleshoot: WCF HTTP Error 404–Not Found

Copying from MPPVE (formerly RCE) documentation:

…might indicate that WCF is not correctly configured.

To resolve the WCF issue

  • The error returned is a “HTTP Error 404 – Not Found”. This might be due to an issue with the WCF scriptmaps registrations. To solve this issue:
    1. Open a command line console as Administrator
    2. Browse to “%windir%\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\”
    3. Run the command “ServiceModelReg.exe –i”

btw, for some more troubleshooting tips regarding MPPVE and the CSM (Composite Stream Manifests) files the latest version creates in specific, checkout:
