@Konard Now they are better?

@FreePhoenix888 @TwinkmrMask do you have any ideas how to make these comments better?

 /// <summary> 
 /// <para>Initializes a <see cref="Range"/> instance.</para>

 /// </summary> 
 /// <param name="minimum"><para>The minimum value of the range.</para><para>Минимальное значение диапазона.</para></param> 
 /// <param name="maximum"><para>The maximum value of the range.</para><para>Максимальное значение диапазона.</para></param> 
 /// <exception cref="ArgumentException"><para>The <paramref name="maximum"/> is less than the <paramref name="minumum"/>.</para><para><paramref name="maximum"/> меньше <paramref name="minumum"/>.</para></exception> 

Take an example from here. Check how they have written Exceptions. Shorter: remove Thrown when ... from your exception description, write only the condition when the exception throwns.
By the way I would recommend to read about recommended tags for docs.

Nice one, can you please apply your changes to all constructors? Make a commit with a message Closes #47 and it will close this issue.

Should I push it into main branch directly or create a branch and pull request?

@FreePhoenix888 directly.

Gentlemens, the <summary> tag is closed 2 times
There was also an agreement to write at the beginning of <param> Представляет/Represents something
For example:

Represents the minimum value of the range.

Do you have any thoughts how to improve documentation here?
