VS2015 Unable to start the IIS Express Web server (resolved)

VS2015 Unable to start the IIS Express Web server

First of all, I have a problem. This project was created in the company's computer, and the operation has always been normal. Copy the project back to do today.

On your computer, however, you are prompted to fail to start the IIS Express Web server.

Modified the configuration file to modify the Web configuration. Found to have no effect. Then began to find a solution on the Internet, to find a number of kinds, there are changes to the configuration file, there are increased permissions, try a few have no effect, not suitable for my situation.

Later looked at the system application of the log, in fact, the writing is still very clear, mainly aspnetcore.dll not loaded, and then from this side to start, and finally found a solution.

This need to download an update about VS2015

Microsoft. NET core 1.0.1 vs. tooling Preview2:https://www.microsoft.com/net/download/core

Once installed, the program is ready to function. IIS Express is also running.

Then I guessed that there could be two reasons for the problem:

First, the company's computer installation of the VS2015 at the same time installed the. NET core components, and the home computer is not installed

Second, the company's VS2015 has been updated, it may be that the update hit the update package. And the family VS2015 has not been updated.
