Error phenomenon

Run the VC# program and prompt as follows:

The code is as follows:

Unable to find a version of the runtime to run this application.

A preliminary study on the reasons

This means that the corresponding version of the .NET runtime is missing and the corresponding .NET Framework needs to be downloaded. To put it bluntly, you need to install the running environment, just like you install some game software that requires you to install something first.

Delve into the cause

Microsoft's .NET Framework versions are roughly 1.x series, 2.0,3.0,3.5 SP1, 4.0,4.5.

1) .1.x series is very old. At that time, .NET was not mature enough to be ignored.

2) .2.0,3.0,3.5 SP1 bases are all 2.0,3.5 SP1 is installed, so the software developed on 3.5 SP1, 3.0,2.0 can be used, so we generally download a high version of 3.5 SP1 (at least Windows XP SP2 is required)

3) .4.0 requires at least Windows XP SP3, this version does not include the previous version, that is to say, it can run software developed on 3.5 SP1, 3.0, 2.0, it can only run software developed on 4.0.

4) .4.5 requires at least Windows Vista SP2 and Windows 7 SP1. I believe very few people dare to use this version to develop in China, because most of China is still Windows XP users, so this can be ignored.

Solution.

In other words, if you are not sure which version the software was developed under, it is recommended to install both 3.5 SP1 and 4.0.
