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

Error phenomenon

Run the VC# program, the prompt is as follows:
Copy the code
The code is as follows: Unable to Find a version of the runtime to run this application.

Preliminary reasons

This means that the corresponding version of the .NET runtime is missing, you need to download the corresponding .NET Framework. To put it bluntly, you need to install the operating environment, just like you install some game software, asking you to preload what.

Investigation Reasons

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

1).1.x series is very old, at the time.NET is still immature and can be ignored; 2).2.0, 3.0, 3.5 SP1 base frame is 2.0, 3.5 SP1 is installed, then at 3.5 The software developed on SP1, 3.0, and 2.0 can be used, so we generally download the high version of 3.5 SP1 (requires at least Windows XP SP2); 3).4.0 requires at least Windows XP SP3, this version does not include the previous version. In other words, it is not that you have 4.0, you can run software developed on 3.5 SP1, 3.0, 2.0, it can only run software developed on 4.0. 4).4.5 Requirements are at least Windows Vista SP2, Windows 7 SP1, I believe that in China, very few people dare to use this version to develop, because most of China is still a Windows XP user, so this can also be ignored.

Solutions

In other words, if you are not sure which version of the software you are developing, it is recommended to install 3.5 SP1 and 4.0.
