In a Silverlight tag demo in the afternoon, when debugging the Silverlight application with vs2010, a window prompt appears, causing the following error:

Message: Silverlight developer Runtime is not installed. Please install a matching version.

Silverlight developer does not initialize and install it during runtime. Another possibility is that the current runtime does not match the Silverlight version. OK! Check the Silverlight version of the local machine no matter what causes this problem. Go to the Silverlight official version test page. The test results are as follows:

Silverlight version: (4.0.5.524.0) indicates that Silverlight developer Runtime is not installed. Download and install one. Download Silverlight 4 developer runtime from the official website. Note that the corresponding runtime version is 4.

After the download is complete, start the installation:

What is the problem? To develop SL, We must install the SDK and runtime. However, the official website published a silverlight_tools.exe to help us install it at a time, which is convenient, but the problem arises. In this way, we do not know when we have installed the runtime with errors, but do not know what is going on. Stopped. We need to install the "Silverlight cmd.exe" runtime. So what are the differences between them? Careful people will find that Silverlight development .exeis a little larger than silverlight.exe. When an exception occurs, Silverlight development .exe can provide more detailed exception information, so developers need to install this version, it can also be said that this is for developers.

Silverlight.exe is called runtime and SDK (software development kit.

In addition, Silverlight cannot be automatically installed as it violates Internet software use regulations. Do not be rogue.
